same here, i think, cool breeze reflector, with 6" inline.
and a generic wing. the cool tubes, with some nice glas stay very very cool, i can put my wrist a 2-3" inches comfortably away from the tempered glass lens.
but, the right color temp 200w fluro will bud 1 or 2 fairly well. those moguls still put off some heat, nothing like an exposed HID, but they are expensive, and lose a lot of out put with in so many months.
thats an old debate though... i tried getting around using HID's, and it became clear after so long what needed to be done. a self contained 150hps with 4 or 2 42w 6500k cfls would stretch out and bulk up a serious little fucking plant. they dont get too hot, and with a little 10"
inline HoneyWell or something aimed at it, i doubt heat would be much of a problem, and are incredibly light, the bulb feels like the heaviest part.
check out T-5 florescent lights if you havent already, those are some high out put skinny fluro tubes, they could replace a metal halide. but the HPS... thats hard to do, it really is more economical and a lot cheaper in the long run.
if you decide you enjoy this, that is... haha there are lots of small 250hps cooltube-stealth- grow box plans out there that are tempting to just try for the hell of it. such arrangements are most ideal for a SCROG grow, which you have mentioned. check it out.
shes i mean IT looks great man
- keep it up!
