I was looking at another thread and started thinking. So could you use a mercury vapor light for veg? Is it the same as a mh? I got a 175w mercury vapor light at lowes for about $25 so thats why i'm asking. If its not the same do you think I should take it back?

Well how much do you think it is? I bought all kinds of stuff and if that hps is around $50 then I can get it. I bet its not though. Is it the bulb or/and the ballast because I already have a 400w hps bulb but I don't have the money to buy a ballast. I found one for $55 but I still don't have that. Thanks for all the help.

Does lowes have mh light also?

Yeah I took everything I had back. I had a 175w light. 4 cfls, 4 light sockets, and a timer. I did see their hps lights and I seen their mh light but like chronicchef420 said, the cheapest one was like $80 and I already have a 400w hps that I need to get a ballast for. I found a ballast for $55 so I'm going to go ahead and get that. Thanks everyone.
