I cant really comment, im on my first grow right now...All my plants are in 3gallon smart pots though, except 1 that is in a 2gallon smart pot. They are 9 days into flower right now so you can see the size of them + i topped each one...1 i actually topped in multiple places because it had so many main shoots, but i also thought it was gunna turn out to be male so I kinda went crazy with it. its about 3ft tall
