Come learn how to easily grow organic cannabis at home! This article discusses soil options, seed selection, containers, and tips for ongoing care. It’s possible to grow marijuana at home, both indoors and outdoors. However, there are many things you need to know before buying your first cannabis seeds. For many, growing cannabis in a greenhouse is simpler than creating an indoor grow room. Greenhouse growers find it easier than growing cannabis outdoors.

How To Grow Cannabis Organically: Seeds, Soil, Containers & Care

The topic of “how to grow cannabis” has such a funny vibe about it. If you browse around online, you’ll see there are many cannabis growers with extremely strong opinions about “the right way” to grow cannabis, though all of their methods vary… Esoteric language, expensive supplies, and complicated recipes or instructions are often used, making it a very intimidating and confusing subject for new home growers.

I am here to hopefully take some of the mystery out of it for you! The methods we choose to use for growing cannabis here at home are pretty dang simple! Sure, there are some steps to follow and supplies to gather, but growing cannabis is not all that more complicated than growing high-quality organic food at home. Or at least that is how we approach it. All you need is rich healthy soil, a large container, and either cannabis seeds or started seedlings – called “clones”.

Read along to learn about our preferences for soil, containers, seeds, and how to get started growing cannabis at home, organically!

This article will get you started with your growing season, then check out the follow-up posts for ongoing care – with tips on routine fertilizing, organic pest control, and how to harvest, dry, and cure your cannabis too. Keep in mind that our goals are not all about high yields. The goal is to grow safe, high-quality, organic cannabis that we can utilize and enjoy with peace of mind – knowing how it was treated from “bean to bowl”. It is about quality over quantity, though we end up with more than enough anyways!

Note:

This post is intended for people living in states who are legally allowed to grow cannabis at home, either medicinally or recreationally. If you have any questions about this, please refer to your local cannabis regulations. Note that today’s post is also geared around growing cannabis naturally outdoors, so I will not touch on light deprivation or indoor grow set-ups. I do plan to write an indoor grow guide in the near future, but most of the tips in this article can easily be applied to an indoor grow too!

SOURCING CANNABIS

Where to get cannabis seeds or clones

Keep in mind that cannabis has not been legalized at the federal level – with the exception of low-THC, high-CBD hemp. Therefore, even if you live in a state that has legalized marijuana, shipping cannabis seeds and products across state lines is technically still illegal. But it is commonly done nonetheless. To my knowledge, people buy cannabis seeds online fairly easily and without issues. However, if cannabis is legal in your state, the most safe and “by the book” way to procure seed or started plants (clones) is from a licensed cannabis store.

Here are a few reputable places that discreetly sell cannabis seeds online:

    – A popular ‘seed bank’ with a huge selection, including CBD! (money order only) (autoflower seeds only) (based out of the Netherlands, ships to US) (UK, ships to US)

Keep reading to the “Cannabis Growing Conditions” section below for information on exactly when and how to start cannabis seeds (or plant clones).

Feminized, Regular, or Autoflower Seeds

Cannabis comes in many shapes and sizes! Obtaining feminized seeds or plants guarantees that they will flower. Aka – they’ll grow buds. “Regular” seeds could grow up to be males. They’re pretty useless unless you want to breed plants. Any males in vicinity will pollinate your female plants, make them produce seeds in the buds, and reduce their THC development. Most people cull the males before they produce pollen to avoid this. We grow with feminized and sometimes regular seeds too.

If you do grow regular seeds, see this article to learn how to determine the sex of your cannabis plants in the early pre-flower stages. You may also want to start regular seeds a few weeks earlier than you would feminized seeds, which allows for ample time to ID the ladies (or gentlemen).

For a super-quick growing season and small, manageable plants, you could try autoflower cannabis types. Autoflowers are available in feminized, sativa, and indica options too.

Young cannabis seedlings we started from seed. If the seeds are ‘regular’ (not feminized) we usually pot them up into larger nursery pots (shown in the background on the right) until we can identify if they’re male or female. Once we identify the ladies, then they are transplanted into their final grow bags, shown on the left. If this sounds too involved, stick with feminized seeds to start!

Strains: Sativa vs Indica

Sativa-dominant plants are typically more uplifting and energizing. Sativa plants also get taller, lankier, and take longer from seed to harvest. Indica-dominant strains finish a little faster, pack on fatter buds, and are generally shorter and wider plants. These make them a preferable variety for northern climates with shorter growing seasons. Indica is also known for more of a mellow, sleepy, heavy, couch-lock kind of vibe.

We generally prefer uplifting, happy, energetic sativa-dominant hybrids – ones that are balanced with enough indica to keep things smooth, relaxing, and still make for a great night of sleep. “Maui Wowie” is a long-standing favorite here, and “Rosetta Stone” is our new go-to lately.

Beyond all of these broad categories, each strain will also have unique attributes that may make it more or less desirable to you. Find what suits your needs! What works for us may not be what works for you. To read more in-depth on the differences between sativa, indica, and autoflowers (including their health benefits) check out this post.

THE PERFECT CANNABIS SOIL

If you checked out our post about how to build the perfect organic soil for raised beds, our methods for building the perfect cannabis soil isn’t all that different. We’re shooting for something that is rich, biologically active, full of micronutrients, and has an excellent balance between moisture retention and drainage. Reference that raised bed soil post if you want to dive deep into detail, but otherwise here is a quick-and-dirty for cannabis soil:

I’m going to give you all two options below. One is a little more involved, which is crafting your own soil from scratch. This is what we do. The second option uses pre-made soil, and requires less ingredients and steps upfront.

Either way you choose to go, please note that we follow a no-till method. That means the soil is a one-time upfront cost, aside from some amendments you’ll need on an ongoing basis. Those last a long time before needing replenishing too! At the end of a growing season, the mature cannabis plant is cut down at the soil line, and the roots left in place to decompose over the winter with the aid of worms and light moisture. The soil is used year after year in the same container, improving with age. This is also called ROLSrecycled organic living soil.

Here are two of our 25-gallon cannabis grow bags, full of recycled organic living soil. These are kept in a shed over winter (and some outside too), and kept alive with an occasional light watering. The soil is reused the following season.

Option 1: Our Organic Cannabis Soil Recipe

Combine the following ingredients. If you plan to fill several large containers (like grow bags – discussed below) then it may be easiest to mix all of these in a very large tote or even spread out on a tarp, and then add some to each bag. Note that it is best to pre-moisten the peat moss before mixing it with everything else. Peat tends to be hydrophobic when dry, and can make your soil less likely to absorb water well if it is mixed without wetting first.

Soil Base:

  • 1 part Canadian sphagnum peat moss (We often use Roots Organics or Premier – both found at our local ‘grow shop’.)
  • 1 part high quality compost (We love Malibu’s Biodynamic Compost, but it’s only available on the West Coast. There is a similar East Coast option by Coast of Maine. You could use aged homemade compost, or shop around to see what is available. Maybe there is a local worm farm in your area?)
  • 1 part aeration additive (We prefer 3/8-inch Lava rock, aka lava cinders. You could use pumice or perlite instead.)

Evenly mix in the following amendments:

    , ½ cup per cubic foot of soil* , ½ cup per cubic foot of soil , ½ cup per cubic foot of soil , 2 cups per cubic foot of soil , 1 cup per cubic foot of soil , 1 cup per cubic foot of soil
  • A handful of worm castings and a few compost worms, if possible
  • Optional: Biochar, 2-4 cups per cubic foot of soil

*In the recipe above, when I mention the amendment amounts “per cubic foot of soil”, I mean the total combined volume including peat moss, compost, and aeration. Also note that all of these amendments are things we also use in the garden, and last many seasons!

Curious about what all these things are for?

Kelp meal contains over 70 different vitamins and minerals. It helps promote overall plant health, vigor, and tolerance to stress, pests ,and disease. It is also a renewable, sustainable resource – so that’s a huge plus.

Neem meal enhances microbial activity, making your soil even more alive! It also strengthens root systems, and can help control unwanted nematode populations, fungus, and soil pathogens.

Crab or Crustacean meal is high in chitin, which stimulates the soil food web and beneficial microbe activity. It may also help combat root knot nematodes. This meal contains both macro and micronutrients as fuel for the plants.

Rock Dust contains micronutrients and trace minerals that are essential for a plant’s core biological processes to work at their strongest, such as nutrient uptake and photosynthesis.

Gypsum contains calcium and sulfur, and helps the plant better utilize and uptake potassium, which is one of the key macronutrients that all plants depend on for life. In the “NPK” ratio for all fertilizers, the K stands for potassium. Adequate potassium availability and uptake enables plants to photosynthesize, produce energy and important enzymes during growth, and also assists with water uptake and drought resistance.

Oyster shell flour is an excellent source of calcium for the plants, as well as phosphorus. Adequate calcium carbonate protects plants from heat stress, makes them more resistant to disease and pests, strengthens plant cell walls, and increases nutrient uptake and overall vigor. Oyster shell flour also acts as a pH buffer.

Here is a little video of our organic living soil in action:

A note about peat moss:

Peat moss gets some flack for being not very sustainable. However, it also gets some of the best reviews and results for growing cannabis. Cannabis likes very slightly acidic soil, which peat moss naturally is. It is also an incredibly common ingredient in almost all bagged soil, so it’s hard to avoid in the gardening world. Aaron put together our soil before we were fully aware of the environmental concerns. Because we are reusing and recycling it each year, the best thing for us is to continue utilizing it!

Some people who grow cannabis choose to replace the peat moss portion of this recipe with coco coir, which is a more renewable, sustainable material. I can’t speak to its effectiveness because we haven’t used it for cannabis, though we do add a little coco coir to our raised beds sometimes, and also use it as bedding in our worm bin. Honestly, we have heard not-so-great results and read numerous studies that show coco coir has inferior performance to peat moss.

Option 2: Use Pre-amended Bagged Soil

If mixing up all those amendments sounds a little too “extra” for you, you could do the following instead:

Use mostly pre-made, high-quality, bagged organic soil. If you have access to it, try to add in a little rich aged compost, worms, worm castings, and/or aeration too! Experiment with building your own soil, with a premade base. Check out this post on how to start a super simple worm bin, if you’re in need of worm castings! They can also be purchased.

For this method, you could skip a lot of the additional amendments upfront, though you’ll still want to add some as the growing season progresses. Cannabis is a hungry plant! The choices and availability of bagged organic soil options will vary depending on where you live. If you can, get top-of-the-line stuff – it is going to be more pre-amended for you.

Examples of popular cannabis soil brands to keep an eye out for are Roots Organics products, Fox Farm’s Ocean Forest/Happy Frog, or Recipe 420 by E.B. Stone. Even some of the Kellogg or G&B Organics could work well, especially when premium compost is added. Check to see if there are any hydroponic stores or “grow shops” in your area. Those stores cater to cannabis growers, and are more likely to carry premium bagged soils over the stuff at big box nursery centers.

Now that you have a soil choice in mind, what are you going to put it in?

CONTAINERS FOR GROWING CANNABIS

We prefer to grow our cannabis in grow bags, and I’ll explain why below. If you want to stick your plants in garden beds or right in the ground, be my guest! This is just what works for us. Check out how to build a durable and deep raised garden bed here.

Benefits of Grow Bags

The preferred container for growing cannabis for many people, ourselves included, is in large fabric grow bags. As opposed to a hard-sided container, they promote better aeration, drainage, and even moisture. Solid containers like 5-gallon buckets could be used, but have the tendency to be drier on top and soggy on the bottom. Grow bags also accomplish something called air-pruning. When the cannabis plant’s roots near the edge of the bag, the exposure to air naturally prunes them back. This is a way to keep the plant happy and healthy in its given container, naturally limiting itself and keeping the roots healthier. In contrast, a solid container allows the plants roots to continue to grow in circles around the container and themselves – becoming root bound. This is not a good thing.

Grow bags are great because they allow people to grow cannabis in a variety of living situations, be it on a patio, indoors, or in a greenhouse. By using a container, you have ultimate control over the soil you choose to fill it with.

Additionally, you can make them mobile! We make rolling dollies to sit all of our cannabis grow bags on, out of 2×6’s and heavy-duty casters. See the photos below. That way, we can easily roll or rotate the large (and heavy!) plants out of our way or into better sun as needed. If you do the same, make sure you get casters that are rated for at least 50 to 80 pounds of weight per wheel, minimum. Ours are 2″ and okay for the flat patio, but 3-inch wheels probably would have made it even easier to move.

Our DIY dollies with casters. Three redwood 2×6 boards are held together by a supporting 2×4″ in the opposite direction, screwed into each board. To catch runoff, we use large plant saucers. This one is 25-inches (top rim to rim) and can hold the 25-gallon grow bags that are 21″ at the bottom. Lava rock is sitting in the bottom of the saucer to keep the grow bag from sitting in standing water.

Grow Bag Brands and Sizes

The bags we prefer to use are the Smart Pot brand, or GeoPot. These are extremely durable and long-lasting. You get what you pay for. We have used cheaper grow bags in the past and they rip and degrade within a season or two of use. Smart Pots will last for years and years. We have bags that are three years old and still as good as new. Call me silly, but I also love being able to choose tan or brown colored bags. I like a pretty garden space and prefer the look of those to the stark black choices.

The size of your grow bag will dictate the size of your cannabis plant, and its health. Obviously, the size of your space will determine how big of bags you can use too. The smallest I would suggest for a traditional photoperiod plant is about 15 gallons. We generally use 20-gallon or 25-gallon bags for those big girls.

If you have a lot of room and want really large plants, you could go even larger! On the other hand, if you are growing autoflower cannabis plants, a 5-gallon or 7-gallon bag would work just fine. Not sure what the difference between a photoperiod and autoflower cannabis plant is? Check out this post that explains it all.

Okay, we have our soil and our bags… now on to the most important part of this post: the cannabis itself.

See how big they can get? Those are our Maui Wowie girls. Also note the DIY dolly below the grow bags. We can easily roll them aside when we want to enjoy our patio space, and put them more in the middle when we’re not outside.

CANNABIS GROWING CONDITIONS

Timing

In most places, cannabis seeds are started indoors in March or April, and transplanted outside in April or May once the risk of frost has passed. Basically, cannabis seedlings need to be protected from freezing or other harsh conditions – just as any other seedling does! If you aren’t sure about your area’s frost dates, stop by this article. In it, I share veggie seed-starting calendars for every USDA hardiness zone. For cannabis, you can essentially follow the timing recommendations for tomatoes (but on the later end of the given windows).

Depending on the strains you are growing and your summer daylight hours, the average cannabis plant will continue to grow larger in size (in its vegetative state) until the days begin to shorten and it receives less than 12 hours of sunlight per day (e.g. after summer solstice). Then, it switches into its flowering stage and begins to develop buds. Most outdoor cannabis plants will be ready to harvest in September to October. The exception to this would be for autoflowers, which can start and finish their entire life cycle in as short as 3 months.

Starting cannabis from seed

We prefer to grow from seed. Once we obtain seeds, we treat them pretty much like any other garden seed! They’re germinated in 4” pots full of seedling start mix, inside on a heat mat. Keep the containers covered and moist until they sprout. Ideal germination temperature is around 75-80 degrees Fahrenheit.

After sprouting indoors, cannabis seedlings need strong bright light – such as that provided by a supplemental grow light. Unfortunately, a sunny window will not provide enough light, and the plants will get extra tall, weak, and leggy. Once our seeds pop indoors, we move the cannabis seedlings to our greenhouse for a few weeks before going fully outside. We also use lights for growing autoflowers in the off-season in the greenhouse. (See this article for more information about choosing and using grow lights.)

To read more in-depth information about how we start seeds, check out our seed starting 101 post!

Cannabis seedlings in our greenhouse, being treated just like the peppers, eggplants, and other garden plants!

Note that you do not need a greenhouse or fancy supplies to start cannabis! If you don’t have a heat mat, I suggest pre-soaking the seeds in non-chlorinated water overnight before planting. This will aid in germination. In lieu of seedling start mix and little pots, another option is to germinate the seed inside a moist root riot cube, then plant the whole cube in its final grow bag after it sprouts. If you aren’t equipped to raise seedlings indoors for several weeks, plan to start in late April to early May. Most locations will be adequately warm enough by then for the seedlings to go right outside after germination (or to sow seeds directly outside, if you wish).

Once they’re a few weeks old and the weather is right, we transplant our seedlings outside to their final large grow bag. When they are transplanted, we sprinkle some mycorrhizae in the planting hole and on any exposed roots. Mycorrhizae enhances nutrient uptake, and disease and drought resistance. If you did have your seedlings indoors under lights for a few weeks, don’t forget to properly harden them off before moving them outside! This helps to strengthen them and prevent transplant shock.

If you are growing from clones instead (such as those you purchase at a local dispensary, or obtain from a friend), you can skip straight to potting them into grow bags outside.

Some young cannabis plants, recently transplanted into their final large grow bags. The small support stakes will be replaced with larger ones as they grow.

Sun and Support

Full sun is best! If you have a wide open location that receives full sun all summer and into fall, you’re in luck. We have changing sun patterns, with some shade from our house and trees to contend with. That is the beauty of putting the grow bags on dollies – we can move them around to receive the most sun possible as the seasons change.

Provide support for the main stalk with a sturdy stake. As the plant gets larger and starts to put on bud weight, you may find the need to further support individual branches. This will depend on the strain. Some growers get crazy with their support and training systems! We start with a small stake for seedlings (shown above) and then swap it to a 5 or 6-foot tall stake as the plant matures.

Water

In regards to water, the goal is to provide consistent, even moisture. Do not let the soil completely dry out between watering, but don’t drown it out either. As with many things, this will vary a lot depending on your climate. If you’re in a very hot and arid place, you will need to water more frequently than someone in a cooler coastal climate like ourselves.

As the plant grows and the root ball gets larger, it will drink water faster and therefore need more, and more often. I will write a follow up post about watering and fertilizing (which often go hand-in-hand) throughout the growing season soon.

If possible, use dechlorinated water. It isn’t a deal-breaker, but the plant and soil microbes will definitely appreciate it. If you are on city tap water, allowing a bucket of water to sit out overnight can help the chlorine dissipate. We mostly use our captured rainwater. Another option is to use a simple hose carbon filter to remove chlorine.

Mulch

Mulch the top of your grow bag to maintain a healthy soil. We love using biodynamic accumulators that not only provide moisture retention, but will later break down into more nutrients and energy for the cannabis. Some examples of biodynamic accumulators are borage, comfrey, yarrow, and dandelion greens. Fava bean greens are also excellent for green mulching, since they’re nitrogen fixers! If you don’t have access to these types of plants, straw or hay will work.

I don’t know about you… but to me, that mulch is looking super sexy! Yarrow, comfrey, borage, lavender, dandelion greens, and straw.

Another popular mulch option is to use an organic cover crop seed mix, and lightly working it into the top inch of soil when you first plant your cannabis seedling. As it gets watered, cover crop will grow under the canopy of your plant. It becomes a living mulch, and also enhances your living soil food web. As it grows tall, you can “chop and drop” mulch with it. That is when you trim it and leave it in place to decompose as green mulch.

And just like that, you’ve given your cannabis a stellar start! You’ll be enjoying your own homegrown organic bud in no time.

When IS the time right to harvest? You’ll learn that here too. This guide is basically everything you need to know, from the best timing, temperature, humidity, methods, and more.

Once you have your homegrown goodies properly dried and cured, it is all ready to use: whether you like to smoke or vaporize your cannabis (read this important article on the subject), make cannabis-infused oil for edibles, homemade cannabis tinctures, or create healing topical salves. The options are endless!

I hope this all took some of the mystery out of growing cannabis for you. Please feel free to ask questions and pass this post along. To the left, of course. Wishing you the bet of luck with your growing adventure!

How to Grow Marijuana: The Essential Guide for Beginners

Growing your own marijuana is possible, whether you’d like to cultivate an outdoor garden or choose an indoor grow medium. Learn how to grow marijuana indoors and outdoors in our step-by-step guide for beginner cultivators.

Determine Legal Status

One key step to take before starting your marijuana garden is to determine the legal status of cannabis cultivation in your state, including how many plants you are allowed to grow . Some states place a limit on just two cannabis plants, while others may allow as many as 16. Stay informed of the ever-changing laws in your jurisdiction.

How Much It Costs

The start-up costs for cannabis cultivation include materials like nutrition for the plant, grow lights (if indoors), basic gardening tools, and more. For some people, the start-up costs may range in the thousands, but if you’re on a budget, it’s possible to start growing marijuana at home for as little as $200 .

Choose a Location: Indoors vs. Outdoors

Many new growers choose to cultivate marijuana indoors, for practical reasons including discretion. However, there are benefits and drawbacks to indoor and outdoor set-ups.

Growing Marijuana Outdoors

Growing cannabis outdoors can be quite the challenge, even if nature’s doing a lot of the work (i.e. providing light, water, and soil, although you can use your own pots and soil as well). This is because you need to take many more variables into consideration, and you also have to be in the right geographic location to grow cannabis outdoors to its best. Those who do not live in equatorial, Mediterranean, or temperate climates with a well-defined spring and summer season may find it extremely difficult if not impossible to grow outdoors.

However, there are few things more satisfying than cannabis grown outdoors, and many people prefer the effects it can give. Also, if you live in the right environment, have an understanding of your local climate, and have the right space to do so, growing cannabis outdoors can become rather simple, on top of producing bumper yields due to the amount of space available. Assuming there are no drastic weather changes, you merely have to watch your cannabis grow and do nothing but give your plants a little TLC along the way (e.g. a little pruning).

Best Strains for Outdoor Growing
  • Early Queen / Early Skunk Feminized
  • Gorilla Glue #4 Autoflower
  • Kyle’s Skywalker OG
  • Skywalker Haze by Dutch Passion
  • Nikki and Swami’s Lemon OG Feminized
  • Steve’s Dream Queen Feminized
  • CBD Mango Feminized

Growing Marijuana Indoors

Indoor growing is usually best suited for beginners as you can control all the variables. Using soil or a mixture of coco coir and organic nutrients as the medium, a set of 400- to 600-watt lights, a grow tent and some pots, you can successfully grow cannabis indoors without too much hassle.

Best Strains for Indoor Growing

Here are some of the best strains for beginners interested in growing cannabis indoors:

  • Northern Lights (NL)
  • Skunk #1
  • Blue Dream
  • Cheese/Blue Cheese
  • Blueberry
  • OG Kush

In addition to these hybrid strains, autoflowering strains and ruderalis strains are recommended for novice indoor growers.

Using a Greenhouse

The greenhouse can meld together the advantages of both indoor and outdoor cannabis growing. Greenhouses can be covered to produce true dark time, and the cannabis is kept in a protective environment which can reduce the chances of pests (though not as much as an indoor grow).

On top of this, greenhouses allow in natural light, allowing for the full development of the cannabis plant’s cannabinoids and terpenes. Greenhouse growing also uses far fewer resources compared to indoor grows, so less energy is spent on lights and fans. The enclosed environment can also make it easier to hide from prying eyes, and you can use other plants to camouflage the cannabis.

However, greenhouse grows are prone to the seasons, and a good amount of natural light is required. Temperatures and humidity levels are also harder to control. Still, those who want to step into the world of outdoor growing, and who are in a suitable environment, ought to consider a greenhouse.

Decide How You’ll Grow

You have a number of choices for a cannabis grow medium. Here are some of the most common ways to cultivate cannabis, along with the advantages and disadvantages of each.

With outdoor grows, you can use natural soil and sunlight to do most of the work, and many people prefer the results of outdoor cannabis with regard to its smell, taste, and effect. However, growing outdoors can be legally risky, and there are many more variables to consider.

Indoor grows can also utilize soil, and many prefer to use soil as it is a natural source of nutrients and you do not need to add too many extra nutrients from other sources. Good soil is also quite readily available at many gardening stores.

Advantages
  • Cannabis has better taste, smell, and effects.
Drawbacks
  • Weather issues.
  • Legal issues.
  • Pests.
  • Thieves.
  • Wild animals.
  • Requires careful balance of water and sunlight.
  • Potentially only two yields per year (depending on your climate).
  • Overall challenging.

Coco Coir

Coco coir is a natural fiber extracted from the outer husk of the coconut. It’s a growing medium that combines elements of both soil and hydroponic growing. It can be combined with soil or used on its own and is an ideal growing medium for beginners.

Advantages
  • Excellent water retention.
  • Reliable drainage.
  • Lots of air.
  • Roots spend less time searching for food, as you are providing it via nutrient water.
  • Coco coir has a neutral pH range of 5.2-6.8 — ideal for growing cannabis.
  • Reduces the risk of pests, fungi, and other harmful pathogens attacking your plant.
  • Environmentally friendly, and can be reused if prepared properly for your next growth cycle.
Drawbacks
  • Coir bales are often treated with chemicals to ensure that they don’t get infected with harmful pathogens, so read the label or check the manufacturer’s website for information on the coir you’re using to ensure that the chemicals won’t interfere with your plant growth cycle
  • You’ll need coco coir-specific nutrients to boost calcium, magnesium, and iron levels in the plant
  • Some types of coco coir may have a high salt content due to being rinsed in saltwater – ensure the coir has been rinsed with fresh water if this is the case
  • You’ll need to feed the plant nutrients yourself

Hydroponics

Hydroponics is where you grow cannabis using mineral nutrient solutions in a water solvent. Basically, the plant will usually be in a pot surrounded by an inert growing medium (e.g. perlite, vermiculite, clay aggregate, gravel, or sand) and have a nutrient solution pumped through the inert material and into the plant (continuous-flow solution culture). In some methods, the plant is kept in a reservoir of nutrients (static solution culture).

Advantages
  • Large, powerful yields.
Drawbacks
  • Precise nutrient requirements.
  • Knowledge of different strains is required for optimum growth.
  • Aerated water is necessary.
  • Better-suited to experienced growers.

Aeroponic

Aeroponics is similar to hydroponics in many ways, except the plant’s roots are kept in an aerated chamber saturated with fine drops of nutrient solution. The roots are periodically wetted with a fine mist of atomized nutrients.

Aeroponic grows require fewer nutrients and less water compared to hydroponic grows, and unlike hydroponically-grown plants can be transferred to soil mediums without shocking the plant.

Advantages
  • High, efficient yields.
Drawbacks
  • High initial cost.
  • Constant supervision is necessary.
  • Excessive time and stress.

Aquaponics

Aquaponics is a combination of hydroponics and aquaculture which is the growing of fish and other aquatic creatures in a tank. Aquaponics is a symbiotic environment where the aquatic animals’ discharge or waste feeds the plants growing on top, and the plants remove toxic levels of waste from accumulating in the water. Aquaponics systems have been in use for many years, but it is arguable that they weren’t perfected until relatively recently.

Advantages
  • Low water usage.
  • No plant feed needed.
  • Little to no chemical usage.
  • Less susceptibility to pests and diseases.
  • Cannabis plants grow quite well in aquaponic systems.
Drawbacks
  • Smaller area, so fewer plants.
  • High electricity outputs.
  • High maintenance.
  • More complex, so a greater number of points of failure.
  • High costs.

Growing Marijuana From Seeds Step by Step

There are several steps to follow to grow marijuana from seeds. After you select your marijuana seeds, you will carry the cannabis plant through each stage of growth, from germination through to harvest.

Germinate

Spray two to four sheets of paper towels (kitchen towels) with some water so it’s damp but not soaking, put a seed in between them and onto a plate, and wait for a taproot to emerge. Keep the room temperature somewhere between 70 and 90˚F.

Transplant

Transfer the germinated seed to a small pot of soil or whatever growth space you are using. During the seedling stage, it will produce two leaves that open outward from the stem to start receiving sunlight.

This is when you start seeing a mini cannabis plant. Seedlings should be kept at 77˚F with a humidity of around 60%. Cannabis likes a light cycle of 18-hours of white light per day once the leaves have emerged. Use a nitrogen-rich fertilizer at this point.

Vegetative Stage

By this time, you will need to transfer your mature seedling to a larger pot. You can tell when the seedling is ready to be transferred, as the roots will outgrow the plant pot. Cannabis plants grow rapidly at this stage as they take on more nutrients and carbon dioxide.

You can also do some vital checks at this point. One is checking for the sex of the plant. Female plants will start developing two white pistils. Male plants grow pollen sacs. If you see these sacs, remove the plant from the vicinity before it pollinates the females and ruins your harvest.

Keep the temperature between 68 and 77˚F, and the humidity between 50% and 70%. 18 hours of light and 6 hours of dark. Light wattage of around and 125 Watts. Cannabis ruderalis skips this stage entirely and moves onto the next stage (flowering). More nitrogen (N) than phosphorus (P) and potassium (K).

Flowering Stage

This is when the vegetative plant is fully mature and is ready to start growing buds/flowers, and you begin to see the trichomes (little white hairs that are the powerhouse of cannabinoid and terpene production).

Transfer the plant to a larger pot. The plant now needs 12 hours of light and 12 hours of dark. Indicas tend to finish flowering in about six to nine weeks and Sativas 10 to 14 weeks. Most growers tend to go for a maximum of 14 weeks’ flowering.

Prevent light leaks during dark times during the flowering stage. Light leaks can cause the plant to get stressed and produce both male and female organs (called “hermaphroditism”, “hermying”, “hermied” or “hermies”), even in feminized varieties.

Keep the temperature somewhere between 68 and 77˚ F, with the humidity at around 50 percent. Stop giving the plant nitrogen (N) now, but up the intake of phosphorus (P) and potassium (K). Once the plant is in the last week of flowering, flush the soil with distilled water and refrain from adding any more nutrients.

Harvesting

Once your plant is mature enough, it needs to be chopped and dried. But first, you need to know when to chop the plant. Some say you should harvest the plants when 70 to 90 percent of the pistils have browned.

Others look at the color of the trichomes, which start off white, then turn amber, and finally brown. Many say the ideal time to harvest is when around half (50 percent) of trichomes are amber. Too clear, and it can be too soon (but can produce a more energetic effect). Too brown, and the cannabinoids lose their potency (although some may prefer slightly less psychoactivity).

Drying

Dry your cannabis plants in a dry room away from sunlight for about seven to 14 days. Your cannabis plant will be ready for chopping into smaller buds for jarring once the plant stem snaps when you bend them. This is an extremely important stage, as a good drying process will prevent your cannabis from developing mold or mildew.

Curing

After you’ve chopped, pruned, and dried your cannabis, it is usable, but it is not at its best. You will want to put your cannabis into a mason jar (no more than 3/4 full) with an airtight seal. You will then leave it in there for two weeks to one month, opening the jar once a day to let the cannabis breathe. This will break down the sugars and chlorophyll in the bud/flower, and you will get a far more flavorsome product with a well-defined effect.

Growing Tips and Tricks

There are many helpful strategies you can employ to help your cannabis plant thrive. You can even save a dying cannabis plant . Here are some basic tips for growing cannabis to help you get the most abundant yield possible:

  • Do your research and choose the right strain.
  • Monitor daily conditions, especially light and temperature.
  • Provide adequate water.
  • Understand the life cycle of the cannabis plant.
  • Harvest at the optimal time.

How to Store Homegrown Marijuana

Storing your homegrown cannabis properly is essential to keep the harvest fresh.

Airtight containers stored in dark, cool places are ideal. Be sure to avoid exposing your cannabis to excessive light, heat, or moisture, as these elements will degrade the freshness and potency of the plant.

Growing cannabis in a greenhouse

The recent explosion in ‘growing your own’ cannabis includes the rapidly growing community of greenhouse growers. For many people, growing cannabis seeds in a greenhouse is simpler than creating an indoor grow room. Greenhouse growers find it easier than growing cannabis seeds outdoors.

Greenhouses offer protection from the elements, insect predators and grazing animals. Greenhouses also provide a longer growing season. You can plant your cannabis seeds a little earlier than if you were growing outdoors. The greenhouse also protects your plants form the worst of the autumn weather during harvest, allowing you a greater chance of a safe harvest.

The many benefits of growing cannabis seeds in a greenhouse allows growers in northern European regions the ability to grow high quality cannabis with either feminised seeds or autoflower seeds.

Cannabis seeds and greenhouses

Greenhouses can be heated if required. This allows you to optimise the greenhouse environment even if you have unexpected frosts or stormy weather. It also allows you to germinate your cannabis seeds earlier than you might do for an outdoor grow. Read all about how to germinate your seeds in our germination guide.

With a little bit of thought and planning, growing cannabis seeds in a greenhouse can be a safe, secure and pleasurable way for the home-grower to be self sufficient in recreational or medical cannabis. Greenhouse-grown cannabis is incredibly potent when grown from good cannabis seeds. It’s no surprise that more people than ever are growing in greenhouses and enjoying the benefits.

Autoflower seeds in greenhouses

Many greenhouse growers enjoy large harvests of over 100g (dried buds) from each autoflower plant. The protective environment of a greenhouse protects the autoflower plants from the worst of the weather and the extreme low temperatures which can occur especially in early spring and autumn.

Autoflower seeds usually grow from seed to harvest in around 100 days in a greenhouse. Compared to feminized cannabis seeds that is a short life cycle. The short life cycle of an autoflower means it is extra important to optimise growing conditions and environment in order to maximise harvest quality and quantity.

A greenhouse protects your plants from high winds, damaging rain and low temperatures. Insects and pests can be easier to deal with in a greenhouse and less of a nuisance. All these factors are reasons why greenhouses are a great asset for the cannabis grower.

Feminised cannabis seeds and greenhouses

Feminized seed varieties grow very well in greenhouses. Often, they will grow vegatively until they sense the shortening days, and will start to show first signs of bloom around August, depending on your variety. In the northern hemisphere feminized seeds are often grown from around April to October in a greenhouse.

In a heated greenhouse the seeds can be germinated and planted around March/April, depending on your local weather conditions. This allows an earlier start than is usually possible outdoors. That’s because the greenhouse offers extra protection from the worst of the early season weather.

As a result, a greenhouse allows you to grow larger plants which can start earlier and finish later than would be possible growing outdoors without a greenhouse. Many growers of photoperiod feminized seeds routinely harvest several hundred grams, or more, of dried buds from a single plant. Plants can easily reach 2-3 metres tall and just as wide. A greenhouse also protects your plants from the autumn/winter storms. This can allow the greenhouse grower to grow a broader range of later blooming cannabis seeds than is possible outdoors.

Greenhouse cultivation of cannabis seeds. Using pots vs planting directly into the ground

Greenhouse growers are split into two main groups; those that grow their cannabis plants in plant pots and those that grow them directly in the ground. Plant pots can be easily moved if they need to be, for example if visitors, extreme weather or other problems are present. But plant pots will need more frequent watering and occasional feeds. A large cannabis plant in a 10 litre container will need watering daily during very hot weather. That could be a problem if you are away and unable to visit your plants.

On the other hand you may experience less issues with humidity, especially if your greenhouse floor is covered with paving slabs. Growing in containers also allows the grower more control over nutrient addition.

Some greenhouse growers even feed their greenhouse cannabis with automatic systems (e.g. AutoPot, Blumat, dripper systems or similar). It’s possible to grow cannabis in soil, coco fibre or any other grow medium in a greenhouse.

Plants that are rooted directly in the ground obviously can’t be moved, but will survive well even when you are away for a week or two. There is less need to worry about daily watering. If your greenhouse contains good quality moist soil then your cannabis plants will establish an extensive root network which will support a large plant with heavy yield potential. However, if the ground under the greenhouse contains poor quality soil then remove it and replace with good quality soil before growing plants in it. Serious greenhouse growers will dig in plenty of manure and compost at the end of each growing season to ensure optimized soil quality for the following years crop. One advantage of rooting your plant directly into the ground is that you can grow very large plants with unrestricted root space. It’s one way to get XXL harvests. Some greenhouse growers, when using the best cannabis seeds, find that a single plant can occupy the entire greenhouse and occasionally even run out of space. If this happens you can try low stress training to tie down the taller branches. In extreme situations, some growers have even had to remove some roof panels from their greenhouse if the plant grows uncontrollably. Plants which are rooted directly into the ground can be grown using automated feeding systems such as dripper systems etc.

Greenhouse overheating. Protecting your plants from extreme summer heat

One problem with greenhouse growing is that the temperatures can get very hot in sunny mid-summer weather. High temperatures make it difficult for the plant to grow. Leaves may wilt and the roots can find it difficult to provide sufficient water. This can be a serious problem, especially in a heatwave when temperatures inside the greenhouse can be in excess of 30ºC or even 40ºC. At these temperatures the cannabis plant struggles since conditions are so far from optimum. But the determined greenhouse grower can find ways around these challenges.

Greenhouses can be fitted with windows which open in hot weather and close automatically when it cools down again. These allow the hot air to escape quickly. An open door in your greenhouse can allow a cooling breeze to flow through. Greenhouse doors made with panels of fine wire mesh keep insects out but allow air to flow through.

Sophisticated greenhouse growers have watering systems in place to simplify and even automate water delivery. If the greenhouse is not in an entirely private location then it might benefit from a coat of white shading paint. This is sold in garden centres and used to protect greenhouses from overheating on the hottest summer days. For the cannabis grower this shading paint also stops people seeing what is inside your greenhouse, but green plastic plant mesh and tomato plants have also provided excellent cover for many generations of greenhouse growers.

Anyone that has been in a greenhouse on an early spring day will note how quickly they warm up in sunshine. This allows growers to get their preferred cannabis seed varieties started earlier in the season than they could outdoors. This allows the growing season in a greenhouse to start earlier. Your greenhouse will therefore benefit from larger plants and subsequently superior harvests. Cold nights can be mitigated with the use of greenhouse heaters that are available to purchase at any garden centre.

Just as with outdoor grown cannabis, the shift towards shorter days during the summer is a signal to the cannabis plant to start flowering and produce the desired female buds.

How do I get rid of excessive greenhouse humidity?

If you have ever seen your greenhouse windows dripping with condensation then you need to give some attention to reducing greenhouse humidity. Excess humidity creates an unhealthy growing environment for your plants and can encourage bud rot and mildew. Wet greenhouse glass panels will soak any leaves, branches or buds that press against the glass. If you want to ensure optimized plant health then consider some ways to make sure humidity doesn’t damage your plants.

Ensuring air movement and regular air changes in your greenhouse is important. Some of the techniques used to keep your greenhouse cool will also reduce humidity. Having adjustable roof vents which can open to release humid air is a great help. Having a through-draft thanks to an open greenhouse door is also a good idea.

Many greenhouse cannabis growers have fans in their greenhouse to move air around, and even to push air out of a door or open roof vent. This may mean fitting an outdoor, weather proof electricity connection to your greenhouse. But its a small price to pay for improved cannabis quality. A fan will also strengthen the stems of your cannabis plant by mimicking the effects of an outdoor breeze.

Some people copy the large legal greenhouse growers in the USA and fit an extraction fan to pump humid stale air out of the greenhouse. This can be combined with a carbon filter to remove any cannabis aroma from the exhausted air.

How large do cannabis plants get inside a greenhouse?

If the greenhouse grower can get good soil for his plants and (most importantly of all) start with good cannabis seed genetics then the plants can grow into true monsters by the end of the grow season. The greenhouse grower can see cannabis plants reach sizes rarely seen indoors. Many greenhouse growers have grown single plants that have filled small greenhouses and produced several hundred grams of top quality weed per plant. Good quality cannabis seeds may cost more but they deliver far superior results in the long run.

As previously mentioned, some greenhouses have windows that can be opened to let any monster plants grow out. But a safer option is to use cord to try to ‘tie down’ the plants if they do start growing massively. The photos above show what can happen when a prolific strain starts to turn into a large bush that wants to grow as high as a small tree. The plant simply becomes too tall for the greenhouse. The soil conditions, temperatures and good care resulted in a plant that was thriving as if in the jungle rather than a garden in northern Europe.

Of course this type of extravagant growth rarely occurs when cheap cannabis seeds are grown in poor quality conditions with badly prepared soil. Growing a monster plant requires properly dug, well prepared nutritious soil at the start of the season. The pictures show large cannabis plants simply outgrowing the greenhouse, delivering heavy harvests for the grower. The Dutch Passion Shaman variety was bred specifically for outdoor/greenhouse conditions. Shaman combines some incredibly potent skunk/purple skunk parents with vigorous growth. Shaman eventually grew into a bush 3 metres tall and two meters wide, winning the Dutch Passion photo contest award in 2006. In this case the grower was forced to remove a pane of glass from the greenhouse as his resin soaked Shaman outgrew the tall greenhouse. The plant was too strong to be tied down, and security was not a problem on this particular grow so the grower went on to harvest an abundance of top quality greenhouse grown cannabis, despite the obvious size problems of the Shaman.

Cannabis genetics and greenhouse growing

When growing with good cannabis seeds in a greenhouse remember that some plants will grow as wide as they are tall especially if they have plenty of sun, good soil and ample root space. Remember too that a few seeds could provide a years worth of medication or recreational weed, so regard the cannabis seed as an investment and get a good variety. Cannabis seeds are one area of your life where you really don’t need to compromise. Look at the Dutch Passion website for some cannabis cup winning options. Proven varieties for greenhouse growing, especially at northern latitudes, includes Shaman, Durban Poison, Passion #1, Frisian Dew and Frisian Duck. These varieties have been used by numerous repeat growers over many years. They have passed stringent standards for potency, quality, pest/mold resistance and vigour. Growing these feminized seeds in a greenhouse will deliver excellent results.

Early flowering using a ‘darkening system or extending your growing season

Some growers equip their greenhouses with a ‘darkening’ system. Essentially this involves using dark blinds/curtains to create blackout conditions inside even when it is sunny outside. This can be used to simulate short summer days and ‘force’ the plants to start flowering and producing buds much sooner than normal. Although this involves extra expense it is one way of accelerating greenhouse weed production. The grower simply uses the blinds to reduce daily light exposure to 12 hours (or less) and the plants in the greenhouse respond by flowering.

Greenhouses also have the benefit of allowing the grower to extend the end of the growing season. Cold sunny autumn days on the outside become warm and comfortable in a greenhouse and allow plants to ripen properly. Pests are normally easy to control in a greenhouse, and so long as the greenhouse is secure it is a great and simple way of growing.

Many also grow cannabis seeds in polytunnels these days, the benefits of the poly tunnels being much the same as greenhouses. Polytunnels protect against the worst of the elements, keeping the plants safe and giving a long growing season. Polytunnels come in a wide range of sizes and they also offer privacy to the grower.

Greenhouse growing of cannabis has lower ongoing costs compared to indoor growing, where large amounts of cash are spent on grow lights and ongoing electricity use. By contrast, growing cannabis in a greenhouse only requires a seed and some substrate to grow in. The sun provides free energy for your plants to grow.

Greenhouse grown cannabis versus outdoor cannabis

Many outdoor cannabis growers eventually upgrade to greenhouse growing. The greenhouse allows more potent crops, higher THC levels and a better terpene profile due to the protection offered by a greenhouse. Whether you are growing with a large commercial budget, or a small greenhouse with just one or two plants, the quality improvements are always important and appreciated. Because greenhouse grown cannabis plants grow in a more sheltered environment the plants are healthier, enjoying more optimized conditions. The plants can grow without damage from extreme cold, storm/hail damage and wind damage. Pests and disease are easy to prevent and deal with in a greenhouse. A greenhouse protects your plants from the worst of the weather, hail and torrential rain. Greenhouses protect your plants from cold weather, creating a warmer environment where your buds can ripen and mature under conditions which are often far superior to outdoor weather.

Growing cannabis seeds in a greenhouse with artificial lighting

Even in warm climates, many greenhouse growers supplement the natural light with additional light on cloudy days. These days LED grow lights can be used to provide additional illumination which can be automatically switched on when ambient daylight (PPFD) levels drop too low. Growers in cool climates, such as Scandinavia may prefer to use supplemental HPS lighting which offers both light and heat to the plants. Supplemental lights also allow you to extend the natural sunlight hours. This would allow you to grow autoflower seeds in a greenhouse and have 18-20 hours of daily light. Artificial light would be used to give the autoflower plants their preferred 20 hours of daily light with optimized yields and quality.

The experienced grower can use the benefits of a greenhouse to grow larger plants, with improved quality and a longer life cycle. Plants can be started earlier and harvested later thanks to the extra protection offered by the greenhouse. During the cultivation process the conditions inside a greenhouse are better than those outside, promoting improved plant health, superior yields and better potency. Outdoor grown plants, without these benefits, usually offer lower yields and quality.

Where to locate your greenhouse?

If you get a greenhouse it pays to think carefully about the location. When it comes to security, always think about a location which makes it difficult for neighbours or the public to see/smell your crop. Also consider your local climate. If you are living in a cool climate it pays to locate the greenhouse where it will receive maximum sunlight for as much of the day as possible. If you live in a hot, desert climate you may want to consider locating the greenhouse under some trees which will shade the greenhouse during the hottest hours of the day in mid-summer. Mediterranean greenhouse growers may wish to place their greenhouse in a cooler, northern part of the garden where some shade may be present. Remember that when temperatures reach 40-45ºC the temperatures become damaging.

Many greenhouse growers also arrange a hosepipe/water connection near their greenhouse. This simplifies the process of getting water to your plants. The last thing you need on a hot day is numerous long walks from your house to the greenhouse with a watering can.

Greenhouse options for cannabis growers

Greenhouses are available in a wide range of sizes and budgets. The lowest cost ones use a flexible transparent plastic mesh sheet which fits over a small plastic/metal pole frame. These can cost as little as €20 but can only fit a single plant inside. Some greenhouses are designed to be leant against an outside wall of the house. Heat from the house helps keep the greenhouse warm. Greenhouses are also available for people that live in an apartment and have a small balcony. Polycarbonate greenhouses use toughened ‘unbreakable’ transparent plastic panels instead of glass, these are useful if you are worried about safety or have small children. Whatever your budget and space, somewhere there is a greenhouse for you.

Growing cannabis in a greenhouse. Easy and effective cannabis growing

Growing cannabis in a greenhouse is a simple and cost effective way to be self sufficient in your cannabis needs. Greenhouse growing seems to be a rapidly expanding pastime amongst cannabis growers of all backgrounds in a wide range of countries.

The more professional greenhouse grower will take care to introduce new, good quality soil/fertilizer each year and keep the greenhouse clean and tidy to minimise potential for pests and disease. Some greenhouse growers use strategically placed fencing and shrubs to make the greenhouse inaccessible to unwanted visitors and invisible to prying eyes. Greenhouses are cheap to buy. You can buy small low cost plastic ones for not much more than a hundred euros. Even cheaper ones are available with plastic covers. They are available everywhere and come in any shape/size required for all budgets. Some of the modern polycarbonate greenhouses are also opaque giving instant privacy and have lockable doors. What more could you need in your back garden? Remember that poor quality cannabis seeds can’t produce connoisseur quality cannabis, no matter how well you grow them. Invest in the best cannabis seeds you can get from a company with a proven reputation, and enjoying growing your own cannabis in a greenhouse.

Thanks for the wisdom Dutch Passion, trying to prevail over the bad weather now in UK with some of your Frisian Dew. Closed up my greenhouse letting a good air supply breeze through some openings and one hole at the top for rain water to drip down. Wish me luck !

We always hope for one of those late summer periods during the end of flowering, but we’re not always that lucky.
But Frisian Dew should be able to handle some harsh conditions. So we hope you still end up with some great results! Good luck!

Nice info!! I clear my doubt here. Keep sharing such info with guys. And also get more information about cannabis here, https://420expertadviser.com/grow-lights/mars-hydro-600w-review/

Hi there Dutch passion, what is the best feed to put into your plant? Cherrs

We advice biotabs for your plants, super easy organic nutrients which will make your babies happy!

Hi, for a reason I have to move my indoor Plants almost 2 weeks at the end of the flowering period (12h ) outside where they get 11 hours direct sunlight..is it safe? are they gonna go back on vegetative grow again?
Thanks for your advice

This will surely bring some stress to your plants. When you move them outside do they get more than 12 hours of sunlight (not direct but in total)?

Because if they go to an environment where they will have longer days they will go in to vegetative state again and you do not want this if your plant is finishing up flowering.

Greetings,
Joe

I am new at this. My plant has reached the top of my outdoor greenhouse. It is still in veg. stage Would it stress the plant if I remove the greenhouse? I has two doors that are open, so the plant has been getting a lot of direct sunlight.

Hey,
If the temperatures are not too low outside without a greenhouse this should be no problem and should not give a lot of stress to your plant.

Hi.
How many plants autoflowering per square
meter I can put in greenhouse ?

We advice around 4 autoflowers per square meters so they have enough room to grow big

Greetings,
Dutch Joe

help ! I am at week 12 of auto flowers in a GH – but I think the grow has stalled ? super early signs of buds for the last 3 weeks but then nothing ? Started in June. Super bushy and good looking but no bud growth ? Any ideas ? should I start with some bloom nutes ?

After 12 weeks you should definately have some bud production. If you want you can send us over some pictures so we can assist you better. Please send them to [email protected] with some information about your grow.

Greetings,

My plants are pushed up against the glass after two prunes will this effect the plants when they flower?

If the buds are against the glass you have a high chance of bud rot because there is not enough air flow through the buds.

Will my plants still ripen in a opaque green house. Do I need a light in there. They are about 2 weeks from Harvest. But, we are getting down to 12 to 22 degrees Fahrenheit at night

If you could give them some supplemental lighting that would be great. Your plants will have a hard time with these temperatures and with some extra light you can make it a successful harvest

Is it possible to grow cannibis in a green house using a tinted plastic material or polycarbonate that isn’t crystal clear?

It should be possible, but sunlight is very important for your plants. Sufficient light penetration should be possible with your plastic material. Do you know if other plants grow under this material?

Greetings,

I have just received my californian orange seeds thankyou for your fast delivery I have ordered a plastic greenhouse and will be using pots do I germinate them inside my house first ? My garden gets very hot with sun from 9am to 7pm in summer

It is indeed best to germinate them in your house because there the seeds will have a stable environment and temperature.

In the first stage after the seedlings germinate you should be careful with direct sunlight because it can damage them.

Greetings,

Hello, i have Auto Think Different in greenhouse in pot, but i dont know if direct sunlight avaible if better to stay in greenhouse or take pot to direct sunlight as much possible sometimes we have there also 30C, what do you think?Im from Czech Republic.thx for answer and sorry for bad english.

If your pots are mobile, I advice you to move them out of the Greenhouse and in to the sunlight when you have extremely hot temperatures.
If the temperature is around 20/25 degrees Celsius you can leave them in your greenhouse as long as you ventilate enough

Greetings,
Joe

Hello friends I live in a country where the use of marijuana is against the law. I intend to plant a greenhouse. Thank you for teaching me zero to one hundred planting jobs.

I have started plants in a tent 18/6 lighting in Feb have taken out of Tent and put on dressing table before putting them in greenhouse, will they survive?

To give a good answer we would need some extra information like the conditions that you have for your plant on the dressing table. Could you please send us an email at [email protected] with some explanation and perhaps some pictures? Than we can help you from there.

Greetings,

At what stage should plants be moved during the day time from window sill to either greenhouse or garden? (In southern England where it is pretty warm now). I have the option of both garden or greenhouse

Around 2 weeks after your seedlings have come out of the ground you can put them outside. Be careful in the beginning with too much direct sunlight, the seedlings cannot handle too much in the beginning. At the very start you can also take them inside at nighttime to protect them even more.

Greetings,
Joe

Should I use shade cloth over my greenhouse in the hot summer days?

Ventilation is really important in a hot greenhouse, if it really gets too hot you can use a shade cloth as well
