The faster the can start absorbing nutrients from the soil the healthier they will look as youngins, just my 2 cents, its hard as hell to kill those lil fuckers, i brought one back with just 2 tiny leafs on it, and shes a beautiful ladie now
Plant it now, wont hurt a thing, i have planted them with absolutely no roots showing and they are always fine, after all it is a weed it has the will to live, i have absolutely tortured clones before just to see how far i can push it
