Dschwiz,

Just checking your posts...and I see you live in Ann Arbor. I used to grow my own plants back when I was in a different state. I'm trying to get rid of my grow lights (High performance sodium lamps - I think they are 400-450 watts). This is a big industrial unit which can fit in a large closet space. I'm willing to sell it for $300 obo (we can definitely negotiate price). It was used only for one set of crops. I think i used it for 4-5 months of continuously lighting and that is it. Let me know if you are interested. I'll let you hook it up at your place to make sure it works before you purchase it to be fair.
