Cannabis seeds to grow indoors

Indoor seeds are the perfect option for growers looking to optimize every aspect of cultivation. These beauties can thrive in outdoor conditions, but they much prefer a controlled indoor setup that keeps things just right.

Outdoor cannabis cultivation is a centuries-long, global practice. Its indoor alternative has only become popular in the past century, but it’s taken the “420 world” by storm. Why do people choose to keep their marijuana indoors? A cannabis plant grown indoors tends to be shorter than its outdoor counterpart, but the yields remain plentiful. It enjoys the optimal environment, responding with vigorous bud and resin production.

This cultivation system lets you protect your crop from the elements, suboptimal weather, and nasty little critters hoping to munch on its foliage. The space provides everything a plant needs, eliminating the gamble with your climate and maximizing output.

Pros and cons of growing marijuana seeds indoors

Indoor marijuana seeds are an attractive option for growers of all levels, but they’re not a one-size-fits-all solution. There are advantages and disadvantages to consider before making an informed purchase decision. Keeping your marijuana indoors provides security, shelter, and stealth. On the other hand, your plants remain small, and you don’t get to experience the extreme yields of outdoor giants.

In a nutshell, here are the benefits of growing the best indoor marijuana seeds:

  • Better control of all conditions
  • Easy protection from potential issues
  • Greater privacy and discretion
  • Perpetual harvest potential

Some people still choose outdoor setups, though. Here are the comparative disadvantages of indoor cultivation:

  • More expensive to set up
  • No access to real sunlight
  • Less microbial life

In a nutshell, indoor seeds take the gold if you can afford the investment. Let’s explore the perks in a bit more depth.

Save time with quick & easy harvests

Photoperiod cannabis crops in the great outdoors rely on changing the seasons to switch between their three life stages. As a result, the seed-to-harvest period usually takes over six months, from early spring to early fall. Feminized indoor marijuana seeds develop into ripe crops in much less time. Flowering time is strain-dependent and should be respected, but you can half the vegetative stage.

This phase is when your crop produces branches and foliage, not buds and resin. Indoor growers can switch the lights for flowering after several weeks of vegging. That way, you get small plants without too many unnecessary branches. A six-month life cycle is suddenly four months long, and there’s less trimming struggle along the way.

Combine this perk with our cannabis seeds for beginners, and your cultivation journey becomes a walk in the park.

Control your environment

Environmental optimization is the number one reason why many growers choose indoor seeds. Why use clones to ensure the best possible phenotype? Let each seed develop to perfection with a helping hand instead. The outdoors brings unexpected waves of low light conditions and increased humidity, pests, disease, and other cultivation pitfalls.

It’s a different story inside. You’re in charge of the environment, letting you fine-tune the conditions. Get the right lamps, filtration systems, and nutrients for marijuana. Use these modern tools to boost the bulk and quality of every future harvest.

Mimic the outdoor conditions, minus the bad stuff. Your rare tropical strain can easily thrive in a cold state—just up the heating and moisture. Those adaptable indica crops appreciate the lack of climate fluctuations, even if they technically could withstand them.

Never worry about pests and bugs infestations

Your outdoor garden is full of little bugs that find cannabis leaves a treat they can’t refuse. You could stay vigilant, plant companions in the surrounding soil, and install protections. Alternatively, keep your marijuana protected and nip this problem in the bud.

A sealed and sterile grow room runs little risk of infestation. Even if something does slip through the cracks, the adverse effects are less severe.

Grow whenever and wherever you want

This selling point of indoor marijuana seeds started with commercial growers but quickly spread to everybody else. Why smoke six-month-old buds when you can always have the freshest flower in your stash? Growing cannabis seeds inside don’t leave you dependent on the growing season. Sow in December and collect in March. Repeat two more times in a calendar year.

As a bonus, you don’t have to worry about nosy neighbors noticing your crop and giving you weird looks. Indoor setups let you forget all about a lack of garden space or proper shielding to keep it private.

Where to grow indoor weed seeds?

The stellar genomes of our indoor seeds make them suitable for various systems. As long as your space is clean, secure, and adaptable, you can choose whichever setup best fits your situation. As a rule of thumb, seal the cultivation unit to prevent pests from harassing your crops. Install a ventilation system to provide fresh air to your budding plants. Get lamps to mimic outdoor sunlight—even protected strains need light.

What growing arrangements are available? Our community goes for the following:

  • Closets are convenient but far from optimal. Opening and closing the doors can disrupt the light cycle, and the air gets stuffy. Stick to one plant if closet-growing.
  • Space buckets fit a single plant but provide a stable growing environment. Pick a short indoor strain for the purpose. The same rules apply as with closets, but the results tend to be much better.
  • Grow tents can hold anywhere between two and ten indoor plants. These neat devices promise excellent light distribution and protection.
  • Grow boxes are an alternative to a tent you make at home. Choose a sturdy wood or metal base and reflective material with a zipper for the insides.
  • Windowsills are excellent for tiny crops, but they reduce harvest potential. Supplement lights with LEDs and introduce temperature control to improve this setup.
  • Grow rooms are the top choice for dedicated cultivators. Having an entire chamber for your indoor marijuana seed-grown crops eliminates the downsides you’d face with other options.

Indoor Marijuana Seeds

In this collection of the best cannabis seeds for indoor growing, you can find all our picks for cultivating in grow rooms and grow boxes, on windowsills, and in other areas with limited space and artificial light. All strains have been chosen for their ease of growth and manageable sizes that don’t lessen the quality of the crop.

Weed Seeds For Indoor Growing

Cultivating cannabis indoors requires the grower to have not only a lot of patience, but also some equipment. For those who are just taking their first steps in indoor growing, this rewarding activity will require an initial investment to cover the cost of lamps, soil, fertilizers, electricity, and so on. In addition, even before you get yourself some indoor weed seeds, you need to carefully read the basic rules of growing indoor seeds, gradually accumulating the necessary information and clarifying various nuances, which over time will certainly appear.

After you decide on the indoor marijuana seed you want to grow, which is easy to do with the large range at our online store, you’ll need to be ready for the growing process. First, indoor marijuana seeds are germinated and then placed in a soil mixture. The next stage is the emergence of seedlings. The seedlings from the weed seeds for indoor growing should be kept in a moist environment and under constant light until the first two pairs of leaves appear. Once between 3-4 internodes of leaves are fully formed, the vegetative phase begins, during which time the green mass and root system are actively built up. That’s how you’ll start your weed seeds indoor.

Then comes the flowering phase which, even if you choose fast-growing indoor cannabis seeds, will last the longest. During this period of plant development, buds appear and develop, so it’s necessary to feed the plant regularly and monitor its health.

The final phase of indoor cannabis development is maturation, during which big fan leaves start to wilt and the color of the hairs on the buds changes, as well as the color of the resin-filled trichomes. After this, you can start harvesting.

The Benefits of Growing Cannabis Indoors

The indoor environment is believed to be the future of marijuana cultivation, and it’s difficult to argue with this for purely practical reasons. Indoor cultivation appeals primarily to those who don’t have a piece of land to grow on, but the benefits of the best indoor seeds don’t end there. They include:

  • Microclimate control – the grower can adjust lights, temperature, and humidity independently, all while the plants are protected from the elements.
  • Growth control – growing weed seeds indoors allows you not only to control when flowering comes, but also speed up bud growth by increasing the CO2 concentration.
  • Better pest control – indoors, there are fewer diseases and pests that can ruin your crop.
  • Various media for growing – besides soil, you can also grow in hydroponics or soilless media.
  • Multiple harvests a year – possible thanks to microclimate control, irrigation, and lighting systems.
  • Compact and discreet – plants from the best marijuana seeds for growing inside collection are not too large in size and stay discreet, compact, and manageable throughout the entire grow.

Feminized Indoor Cannabis Seeds are the Best Choice

If you take a look at our collection of the best marijuana seeds for indoor growing, you’ll find that almost every single one of these strains is feminized. This is very important, because if a tightly packed grow room contains a male plant, it’s guaranteed to pollinate the rest of the plants at the start of the flowering process, ruining the quality of the crop completely.

Even if you notice a “saboteur” in time, its removal can cause certain difficulties, because you’ll inevitably have to shake the bush. At this point, its seed sacs may open and, again, pollinate female plants around it. Feminized indoor cannabis seeds can help you avoid this problem because there’s a 99% chance that only female plants will grow from these.

Autoflowering or Photoperiod for Indoors?

There is no universal answer to this question. If you want to get a harvest as quickly as possible and without putting too much effort into growing indoor, autoflowering cannabis seeds will be the perfect choice for you. In this case, you can simply plant the germinated seed in the pot, keep it under a lot of light, and water them in time. When growing indoors, autoflowering cannabis seeds don’t require training or large amounts of nutrients. After an average of 2 months, you’re almost guaranteed to get 30-50 grams of buds per bush.

However, if you’re the kind of person who’s not afraid to experiment, wanting to squeeze out the maximum potential inherent in the genetics of the best indoor weed, you’ll probably want to opt for a photoperiodic variety. Unlike autoflowering strains, it will tolerate any yield-boosting techniques and big amounts of fertilizer.

To summarize, indoor autoflowering cannabis seeds yield less, but will do so about twice as fast as photoperiods. On the other hand, photoperiod seeds produce more buds, but will take more time and effort. Either way, you’ll find both varieties in our collection.

Sativa or Indica for Best Indoor Weed?

When it comes to pure 100% Sativa varieties, you can safely say that these in no way make the best indoor strains. A medium-sized grow room simply won’t have enough space to grow a Sativa plant, which can reach up to 3-4 meters (9’10”-13’1”) in height when unrestricted. A good Indica, on the other hand, with an average maximum height of about 1.5 meters (4’9”), is hands down the best indoor seed option.

The good news is that there are no landrace Sativas in this collection; however, there are some excellent hybrids that have been bred and stabilized over the years specifically for growing cannabis indoors. This allows you to focus solely on the effects, THC concentration, and flavor you want, not the phenotype. In our collection, you’ll find the best cannabis seeds for indoor growing to suit every taste.

Best Indoor Seeds
