How to make the most of a high-end strain
After you buy cannabis seeds of premium quality and check their origins are fully trustworthy, it’s time to start looking for an optimal place to cultivate them. In order to do so, it is essential to pay attention to the following issues, if the best results are to be obtained:
- Growing media. Whether you decide to cultivate indoors or outdoors, this element is of utter importance for your seeds’ optimal development, because it helps their roots grow strong and healthy, resulting in stunning marijuana plants.
- Ideal growing conditions. Plants are optimally grown outdoors. However, they can also thrive indoors if the growing area is well aerated, free of humidity and with a controlled temperature. They do not grow as tall as in the open air, though. If you decide to cultivate outdoors, it is important to keep in mind that they deliver better results in regions with long, sunny days.
If your Humboldt Seed Organization marijuana seeds are stable, potent and heavy-yielding, and you place them in an adequate growing area using the perfect media, your seeds are sure to show their greatest potential. Outdoors, plants can even turn into huge 3-meter tall trees capable of producing amazingly generous crops of cannabis buds.

A groundbreaking collection with old-school genetics
One of the main concerns of Humboldt Seed Organization is and has always been that all our genetics, not only those already in our catalog but also the ones that are still under development, finely preserve the so-coveted traits of those strains brought to California more than 20 years ago. Potent genetics with noble origins that showcase top-notch old-school traits.
Humboldt Seed Organization is a marijuana seed bank located in the United States, in northern California, an area of fertile soil known as Emerald Triangle. With such a name, it is not difficult to imagine what happens in there: the precious gemstone, famous for its toughness and its beautiful green color, has often been equated with the tasty, bulky, thick and colorful cannabis buds obtained in this region. The three counties that make it up are Mendocino County, Humboldt County, and Trinity County, all of them noted for their production of cannabis. The climatic and geological conditions of this idyllic, isolated place are perfect for the correct development of marijuana seeds which showcase an amazing potential and overall quality that could be hardly obtained in areas with different conditions. That’s why they have been not only endorsed by American breeders since the 60’s, but loved and appreciated by experts in the field all over the world.
