I just found out that my light is 120 volts is this good or bad ?
I got my HPS 400w from lowes (just the light no ballast) $20, The light ballast was $82.12 from the electrical supply store ( this came with the ballast the ballast and the warmer or what ever that was [the complete wire set up] and no in my adventures building this i have found that the people in the eletrical supply store are not electritions so they can not show you how to wire it up but you might have better luck.). The box I built my self and then i got 3 50 cfm bathroom fans (for vetelation) for $12.18 each, the cheap fans can not handle to much of use 24/7 and will need to be replaced. I have 100 cfm going in and 50 going out.I will have to look into it, I can deal with a 100 $ light right now, after a few plants I might upgrade. Thanks for the help .
