Growing cannabis indoors has unique advantages and disadvantages. Cultivators have almost complete control over the environment, and can easily regulate light, water, and nutrients. However, space can quickly become an issue, especially when growing strains that like to reach rapidly toward the light source.

Fortunately, breeders have tinkered with cannabis genetics to create varieties that are ideal for indoor growing. These plants remain short, and are easy to manage and train. They’re suitable for small grow tents, and some cultivators even go to the extremes of raising them in refurbished computer towers and cupboards for added stealth.

The AK-47 autoflower is one of our favourite classic strains and one of the best indoor cannabis seeds. The AK 47 autoflower is second in this top 5, but actually deserves a shared first place. Thanks to its genetics (Thai Skunk, Mexican Sativa and Afghan) the AK 47 autoflower is known for its extremely high fungal resistance and high yield. Yield can be as big as 675 grams per m2(!). The genetics are very stable and easy to grow indoors. A failed harvest is therefore almost impossible.
