Rival I have a homebox XS with a 250 watt hid in it. I have a 6 inch inline fan that moves 250cfm's IT's still a bitch to keep cool.. I would make sure to have a good vent system and A cool tube for that light cause it's gonna get way hot in there. I dunno about a 400 in the xs. even my 250 is pushing it. I have the yo yo hangers but i dont use them due to a horror story my hydro shop owner told me. I would just go for some chains and hooks. 1
Legacy. Thanks for the info...I appreciate it.
I got a 250w
Hortilux in there right now, and while it's definitely hotter than the CFLs, it's not as hot as I thought it would be. The hood is pretty light in weight, too, which is good. The chains and S hooks seem to be handling the weight of all of it with ease, too.
Aside from all of that, the girls are loving the new HPS.
