However, despite these obvious advantages many people are put off growing their own because they think it'll be just too difficult. In fact, with the correct preparation and knowledge almost anyone is perfectly capable of growing their own marijuana. This is a case where the internet is your friend – there's a mountain of advice and guidance available out there. The other key factor is to choose one of the strains that are easier to grow, and there's a good selection of those available.
Some strains of marijuana plant really can stretch out, especially the Sativa varieties. These can reach heights of up to four metres with outdoor growing, especially if they're left to their own devices with no pruning. So what do we mean when we talk about short varieties? Generally, we're referring to strains that won't get taller than 80 centimetres when they're mature and ready for harvest, although some types can actually be only 50 centimetres tall, or even shorter.
