best cannabis seeds for indoor growing uk

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.

Many experienced growers will not be surprised that we have included Northern Lights in this top 5. Northern Lights cannabis seeds are easy to grow. The yields from this plant can reach as much as 550 grams per m2 in a very short flowering period of just 7 to 8 weeks! That’s what we call super seeds. Moreover, the taste is appreciated by almost every cannabis lover. Haven’t tried Northern Lights yet? Then we advise you to do so!
