I guess I should say that I have inline filters though. I'm sure that makes a difference, but they don't even need cleaning much.Quote:

That looks good.
are those 42W CFL's?
That would mean about 5200 Lumens per hood.
You may want to go bigger.
are these hoods for veg only?
Very good idea.
Now if you could get your hands on some MYLAR and line the insides of those with it you would be good to go.
Only problem now is the inevitable fact that those plastic-tubs will conduct a bit of excess heat. But considering you're using CFLs, even a small to moderatly sized fan can easily circulate the heat out of the area.
yeah i might try and fit a small computer style fan on those hoods. just cuz they are made of plastic.
good luck

No, Those are 27s 5500k. They are what I will be using for veg. For flowering, the largest 2700k bulb I could find that would fit two in a hood was 30w 2k lumens. So I only have space in the hoods for 4k ea hood, 12k lumen total. I was hoping by placing mylar on the entire cab I could use every bit of the 12k. I will also be trying to squeeze in a few more bulbs wherever I can.Quote:

If I keep these hoods as close as I can, and vent them very well, should 12k-16k Lumens suffice in a 2X1 scrog environment.
Don't count yourself out on HID. During Veg I would use the CFL's. But my research shows that 150W HPS will produce less heat than your 180W of CFL's.
Just think... If HPS produces more lumens per watt then the assumption can be made that it burns cooler. Since more electricity is transformed into light, then less electricity is left to produce heat.
I could be wrong on this. But none have corrected me on it.
You should be fine. You will get weed. Very inventive, good job. Of course it would be better if you could do some HPS during bloom. You'll of course get more weed that way. Mylar is way over rated compared to flat white, but it looks like those tubs are kind of glossy. I would get a can of flat white paint or mylar the insides.
Thanks Opie. I really wanted to go HPS, but just didn't want to bite off more than I could chew with the first grow. If it goes well, and I can keep temps down with CFLs I'll try beefing up my fan and going HPS.
The tubs were originally clear. So I painted the outsides of the hood, which left the thin clear plastic on the inside with the white behind it. Is the clear plastic going to interfere with reflectivity. I know the light is going to refract while traveling through the plastic before it hits the white, but I just don't know how that is going to effect the hood.
Also because it is painted, when I turn the hood on, you can see light glowing through the white. Would it be smart to put a black layer over the white so that it doesn't glow ?
The inside of the hood would still remain white, but the outside would be black.
The clear plastic tubs are probably absorbing allot of light rather than reflecting it. That probably accounts for why it glows so well LOL.
Paint the inside and you'll probably reflect more.
