I am planning on a veg box, kinda stealthy, heres the spaceI have:
(I will go another route if it's no good.)
48" high, 34" wide, 21" deep.
This size is perfect, but I could go a little bigger if I have to.

I wanna be able to veg enough plants to keep 1 600wt. busy for now, and double that eventually. So I'm thinking 10-15 plants in the veg box. I want to be pulling a plant out of flower and slappin another one in, a constant flower room, constant veg. Hows my size look, for my goals? Oh, it's gonna be lit with 4x 2' flourescents on top.
