cheapest way to make a hood is an old carboard box, tinfoil and hot glue

Dude that is fucking awesome!!!!

Might be cheap, but i'd be careful using cardboard around that kind of heat

I'm going to be the bad guy. when you put a hood on a bunch of low watt cfl's all you do is trap heat. now the math. you need to keep a cfl 2-4" off the plant to use them for growing. lets say what your using has 100% reflectiveity. It doesn't by the way more like 30-40% at 100% you would only get about 50% light off the reflector. I do back off my statement that the reflector does no good with low watt cfl's. It does have some value. but the heat build up is a much larger neg value. cfl light is great I use it myself. I know my expalatoin sucks but if you reserch how light works I think you'll figure out what I'm trying to say.

metal halide what?

fdd are you making fun of my last post.lol

i making fun of the OP. i know i shouldn't, but how many actual watts is that thing pushing? a 250 MH would do really nice in the area he is growing in. much easier to vent as well.

Not only is it pushing a lot of watts but it looks like the most unsafe CFL setup I have seen. That thing has got to be at least 400 watts... I can tell ya for a fact that a 400 watt MH would grow better plants than that thing. And fdd does have a point about the metal halide being easier to cool, good luck cooling those 16 bulbs or however many are there.

An HPS system is capable at peak to achieve 140lumens per watt,(Usually a fair amount less then that) a CFLs is 90 but it's lumen per watt range doesn't vary as much. Of course heat is simply the current flowing in the bulb so watts represents heat. So is what your trying to say is that a CFLs light is not worth reflecting, but an HPS bulb is? People reflect HPS often because if you can get back even say 5% of the light on a system that powerful then you've added a lot. CFLs are of course much weaker generally speaking but if the room is properly ventilated then I don't see a reason a reflector would be bad. That being said CFLs are so cheap these days I rather just buy a couple extra bulbs. I actually like this guys reflector, though I think he should add a few cumputer fans to the sides and I'd seriously make sure those bulb sockets can handle those amps.
