So I've made a growbox in my closet. It's all set to go. I have three standard light sockets hanging and ready to grow up to seven plants at a time. My question, which is the best combo of bulbs that I should use? I know I should do the HPS thing, but simply cannot afford to install a light fixture. I know cfls are the next best bet, but I don't know which combo to use that'll be best for getting as many pretty buds as possible. Thanks guys.
