the key i guess is making sure you have a big enough root mass to support the thing till the roots dig in, otherwise it may topple over. i imagine you dont want to do this till the plant is 3 weeks or so
how do you keep the upper mass moist until it's set?
others have better input but in the meantime id say that the more deeper the roots can dig affects the height of the plant. it is more meant for autoflowers i think, the way that most of them root they dont take advantage of the upper part of the soil
