Hey their, I have never tried this before, but here it goes, my space is 3feet, by 2feet, by ten feet high, Im thinking of using CFL lights with aluminum for the walls. It is in my closest and I wont be able to put an exhaust in it, just a fan. I am planning on using soil to grow, Im thinking around 3 or 4 plants, and to try to get the as tall as i can for maximum yield. Im just wondering if anyone has any tips, suggestions, thoughts, and also if anyone knew what I could expect using CFL lights and with 4 plants, (northern lights #5) and (green crack) and (nebula) and (hashplant) how much I could expect for a yield growing them as tall as I can. Any and all tips are welcome. PLZ help me!!
