best indoor marijuana seeds

Our Critical feminized seeds are probably one of the best cannabis seeds to grow indoors. And not without reason. Critical is very suitable for extremely small spaces as they do not grow larger than 80 cm. The strain is easy to grow, features a very short flowering time and yields are quite big. When pruned at the bottom, the buds grow at the top. In this way it is possible to place up to 16 plants per m2 which can result in a yield of up to 500 grams per m2.

Amnesia Haze is another classic strain and couldn’t be missing in our top 5 best indoor cannabis strains. The strain is worldwide known because of its very high THC level. Thanks to its properties Amnesia Haze is very suitable for indoor cultivation. The only “drawback” we can think of is the relatively long flowering time of 10 to 12 weeks. However, every disadvantage has its advantage. Due to the long flowering period the weed is extremely strong, the yields can reach 650 grams per m2 and both the taste and the smell are sublime. Keep this in mind, because if you’re sensitive to psychosis, it’s better to skip these weed seeds and opt for milder ones.

AK 47 autoflower

Based on our experiences and customer reactions, we have drawn up a top 5 of indoor cannabis seeds. We have taken into account ease of cultivation and weed quality.

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.

Growing cannabis indoors is becoming increasingly popular which is not surprising as it offers many advantages. You can grow all year round under constant ideal conditions so there is a good chance that you will end up with a cannabis plant with a good yield. However, not all varieties are suitable for indoor growing. And because there are so many different types of cannabis seeds, it’s often difficult to find them. Of course you also want to grow cannabis that meets your preferences. Think of taste, yield, effects and flowering time.

Technically, yes. All strains can be grown indoors—although some varieties are much more suited to this environment than others. Bushy indica and autoflowering strains rarely exceed 120cm in height, and are thus naturally compatible with small spaces.

If you’re planning to grow weed indoors, consider the strains below. They’re ideal for small spaces and produce fantastic harvests.

Why Grow Cannabis Indoors?

Indoor growing makes life easier for many cannabis cultivators. If you live in a cold climate with bad weather, or your garden lacks direct sunlight, indoor grow tents provide a safe haven. The ability to manipulate the light schedule, humidity, and nutrients with precision allows growers to raise weed on their own terms.

Towering sativa strains have the potential to surge to heights of 300cm. Growers can limit vertical growth by planting them in small containers, but they won’t produce as good of a yield as strains specifically bred for indoor cultivation.

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.
