What are indoor marijuana seeds?

Indoor marijuana seeds are those that come from strains grown indoors. These are cannabis varieties that have been adapted over the years to home growing conditions. They have been cultivated for generations under artificial lighting in enclosed spaces with mechanical ventilation and human-controlled irrigation. Indoor seeds have perfectly adapted to this environment and perform better indoors than outdoors, where nature controls all atmospheric factors. This doesn’t mean they can’t grow outside, but they may need favorable conditions and a suitable climate.

What cannabis strains are in the indoor category?

On our list of cannabis seeds, we only present photoperiod strains, which bloom in response to a shortened light cycle. In the indoor marijuana seeds category, you will find indica and sativa strains, THC and CBD seeds, as well as feminized and regular seeds. We do not include autoflowering seeds in this category, as those, while capable of growing indoors, also thrive outdoors. Therefore, autoflowering seeds are placed in a separate category.

What makes indoor seeds unique?

Photoperiod strains differ from autoflowering strains in many external features. The primary difference is in their flowering mechanism. To enter the flowering phase and start producing buds, they need a trigger in the form of reduced lighting time. Cannabis plants interpret this as a signal of the approaching winter and begin producing flowers. Another difference is the size these plants can reach. Since flowering doesn't start automatically like with autoflowering seeds, these plants can grow much larger. If flowering is not initiated, the growth phase can last for several years until the plant dies of old age. The height these plants can reach varies between 2 and 4 meters depending on the seed variety, and it won’t increase after reaching the maximum size.

Which indoor seeds are worth buying?

If you're building your marijuana seed collection, it can’t be complete without strains from the indoor seed category. These are very popular varieties, and most legendary strains belong to this category. If you’re a beginner, go for classic and well-known strains like Amnesia, Lemon Haze, Jack Herer, or White Widow. For more discerning seed collectors, we recommend American varieties like Girl Scout Cookies, OG Kush, Gorilla Glue, or Zkittlez. There's something for everyone.
