Cheapie or not 600wcooltube

Hey guys Iv got a 1x1 m tent and want to upgrade from my growlush 400w hood to a 600w cooltube, Iv been looking on eBay and prices start at 125$ to 600$ , is there going to be a major difference between the two apart from quality of components? I'm guessing that the plants won't know the difference, in which case il go for the cheapie because cash is low at the moment. Cheers buds ,thanks for the input in advance

Basically a cooltube is a cooltube from what I've seen. Some have differnt size reflectors, but that's really personal preference as to what suits your needs. The main differnence is going to be with the ballast and bulbs. I've read good things about the ipower and Apollo kits if that's what your looking at. They seem to be 2 of the cheapest on Ebay. Happy Growing.

I just got a 400W Apollo setup and it seems good. I'd try their 600W if I was going to upgrade.

I also just got the apollo 400w cooltube kit and I love it! Ballast is a little loud but not bad.
