Trees in a 4x8x6.5 space?

Whats the biggest gallon pot someone has used in a 4x8x6.5 grow tent? I was thinking of doing 3 big plants under 1200w in a tent, and maybe use 12 gallon pots, or higher.

No one? Really? Find that hard to believe.

unless you SCROG them or LST, TOP, FIM, Supercrop or something you are gonna run out of vertical space before you can even use a 12 gallon pot.

bingo. stay with about a 5 or 7 gallon geopot. way bangin results since ive switched. plus a 5 gallon geopot is like the equivalent of an 8 gallon plastic pot when it comes to root growth.

5 gal will give u about 4 months of good veg growth before u flip the switch to flower.

I already have all that down. That's what I plan on doing. Gonna lst and top like crazy.
