I also wanted to ask - Anyone with the HTGsupply 400w HPS light? Does the ballast get very hot? The black part you can't even touch your hand to for more than a second or two.. Is this normal? I have fans in there, and the temps are low.. The exhaust is about a foot above the ballast anyway.. I just want to make sure that it's *supposed* to get that hot. Thanks And what's up, no love for my grow?!
