I was contemplating maybe growing one or two plants and have a few questions about lighting. I have a lamp that i used for my snake before I got rid of him, would I be able to pop a HPS bulb into the fixture or will that not work? I have one of those spiral 10w flourescent lights that I could use in addition to lots of natural light, but I get the feeling that the consensus is that's not enough light. So If that fixture won't work for HPS, would one flouro bulb in that fixture work? (in addition to the natural light) What sort of wattage should I be aiming for either for flouro or HPS? I'm going to just stick with one light from start to finish if that helps. Thanks in advance
