Seeing as how quickly the roots can grow I will probably be doing the same when the time comes. Right now I have the 4 older plants in 2 gal. containers and the younger set in 1 gal. Come flip time, I'll step everybody up 1 gallon.
Air Pot Official Site <--- Official site and some videos that show air pots in use. It all seems legit. A 2 gal pot is $6.50 locally, so when my budget allows I'll grab a couple to test them out.
I've looked into topping and FIM'ming and will try one of them, probably within the next couple of days. A quick question while we're on the subject: do I top/FIM only the main branch and then LST, or can I LST and then top/FIM all of the new budding sites? I would think that the 2nd option would create more budding sites but I'm not too sure
