what the..i replied to an earlier thread and it put it at the end??
I can put my hand on my cfl and it feels warm, not even hot. My ballast on each are not even warm feeling, almost no heat at all. Maybe its new technology, IDK. You put your hand on hps 400 watt bulb and you will pull away a giant blister that resembles a hand. I think what is important here, the higher the watt the bulb, the hotter will be. The less surface area to disapate heat, the greater the heat that comes from one point, or small space. The more cfls the more surface area for disapation. the greater the watt for HPS, the greater the heat in one focused point.
I think a 250 watt hps is prob not that bad. A 400 watt is twice as hot. and 1000 watt is three time as hot.
Dont get me wrong, I dont think cfl do a better job than HPS, they dont. I one of those ppl that have heat issues so I use cfls instead.
Have you ever used 400, 600 watt hps? Have you used 400 and 600 watts of cfl?
doesn't mean we do. You may get shit results outdoors, then what, you gonna try to convince everyone that its impossible to grow
that you can only buy it.....because you couldn't get it too work.
You keep your Kelvin Temps in check and you could grow a house full with CFL's
