Growing on a budget

[Perp]

So if I build a wall in the middle of the growroom I could have veg on one side and flower on the other as long as they were light-tight? That would be really cool-

Yes, if it's light tight but that is easier said than done. Its easier to locate the veg in a different area since you don't need a lot of space and the smell is not that bad. But if you can build the light tight wall then I say go for it.
