I'm building a small grow tent using a 130w CFL tube. My questions are about ballasts.
1. Do I need a specific ballast for CFL bulbs or do all ballasts work on all types of bulb?
2. My bulb is 130w but iv'e not seen ballasts below 250w. Is a 250w ballast ok to use with a 130w bulb?
3. What budget ballast would you recommend for a small grow tent using a 130w CFL growing one (2 max depending on size) plant?
