i got my clones when they were about 2 inches put them into 4'' square pots then transplanted into 2 gallon pots 3 weeks later now they are almost 2 feet and i see a root coming out the bottom. i only want them to get about 4 feet tall and yield about a half lb each. they are outdoor and in ff occean forest. do you guys think i should transplant into 3 or 4 gallon pots or will i make my margin? thanks much
