DTRave has a lot of experience with this type of thing. Maybe you could check his threads out, give him a holler.
LolaGal Reviewed by LolaGal on . Pot Stacking... Ok, apparently either I get too busy, or too lazy. Here's the background... I ran a grow thru to harvest. (Indica dom - 5 gallon pot) After harvest, I flushed well, and trimmed remaining foliage for a re-veg in the same 5 gallon pot. I do this with virtually every grow, picking the finest example of the run, and re-vegging for clones. I re-vegged for about a month, and she was ready for the flower room again. When I switched her (around 6 days ago) I transplanted into a 7 gallon pot. Rating: 5
