If you keep your babies in that box eventually they will crowd it, they will compete for light and I've noticed that whenever the leaves of my plant rub up against something for too long, it's never a good thing. (pot rims, the wall, ad etc.) If you are growing in a home that you don't own, tisk tisk...you put your mother at risk. Get her permission first so there are no surprises. Lights! You'll need a lot of cfls or you'll need to get yourself an HID. (Although with an HID you will not be able to hide the electric bill from your mom!) She'll even notice her bill rising with just a few cfls...so, tell her what you plan to do. Seems like you need to do some research but believe me...it's well worth it! Peace.
