A possibility that I'm thinking about right now is adding another inverted tub on top of this one with the lights at the top to give more vertical room. More soil is always doable, and I just got a new (high paying ) job today so money for lighting is solved.

Talking with my buddy about the high it gave us (we smoked it like 6 months ago) we think it's an indica, it came off some dank ass purp that we lovingly called "Darkness."
With some LST and after removing the male (I have this feeling that there's going to be 2 females) I think there'll be enough room.

Going to the store to buy some fertilizer for the vegging right now~
