I am currently growing with CFL's, and considering that they do not penetrate good enough, you can't grow plants out to full height, and they are a pain to keep moving around. I was thinking of getting a 600w HPS light, but I have a few questions about them, since I know basically nothing. How much electricity does 1 600w HPS light emit? Will my electric bill be sky high? Also, about how many plants can you grow with 1 light in a 4 x 4 area?
