hey-
i would transplant into seperate pots. listen to Shovelhandle. planter size should reflect desired final plant size. with the grow "tent" you have, i'd go no bigger than 1 gallon planters. i re-read through this thread and noticed no one gave you any ideas for a CFL setup. here's mine. you could add some braces to it and make it a single unit for your tent. you could at least do one of the 3 bulb strips with Y splitters and run 6 CFLs.
