u.g.u Reviewed by u.g.u on . Minimum Height Growth? To get straight to the point... What is the minimum height a plant (excluding lowryder etc) will grow. (I know it does depend on straine and how long it has been vegitating) I'm trying to use minimum space, and at the moment have 5' high(....width and depth is not a problem..)
