thank you to all the hydro jedi masters, ok so i wanted to grow in a closet, its about 2x4, i dont know if thats too small, but its already bright white, light can't escape when its closed, and theres a sliding window for circulation, and for my hydro set up, i was looking at this 600W HPS Plantastar Bubbleponicsâ?˘ Kit (SH Hydroponics, Inc. > Special Combo Deals) it comes with everything i need, does this sound proper?
