Thanks for the advice. I'm calling an electrician first thing Monday morning. I'll just move everything and take down the mylar that morning...

I think my ballast is switchable to 220V (EDIT: I guess it's 240V). Where the bulb socket plugs into the ballast there is a place for 120V and 240V... so I'm assuming that means it can run on both. I didn't no that dryers ran on a separate voltage! Is that the case 100% of the time? I will try it, I just don't want to fry my ballast... but that would be ideal... then I would only have to pay to repair the old circuit. I don't want to dump to much money here because it's a rental as I mentioned. In fact, I'll probably be leaving after I get this grow under my belt.

Thanks again for your help...
