Had a wild dream last....
I am running a 4x8 tent with 2 1000watt cool tubes. I am using a 240cfm fan for intake at one end and another at the exhaust point, both outside the tent. I also have a 400cfm for a scrubber. I did not hook the 400cfm fan to the lights with the scrubber because of pulling the air through the scrubber would add resistance to try and move the heat out of the lights. I am also running a 8000BTU A/C unit and als a 240cfm at the inlet of the tent. Temps never get about 77 degrees and my girls are looking lovely, bet rez temps are staying at about 75 degrees. I'm all about variables and hopefully this discussion will spark a new "invention" for those with heat problems.
This runs off the same principal as a cool tube, nor like a cool hood. My crude drawing (this is why I grow instead of being an artist) shows my set up currently. As we all know, the more lighting (lumens) you can get to your girls, the better medicine you can produce (tighter buds, more yield......better quality in general) and since everyone said that heat was going to be my biggest enemy with my set up, I think I've gotten it pretty well under control. What I was thinking about doing was repositioning my scrubber and dropping it to the ground and adding a piece of 4x8 plexi glass directly under the lights, and reconfiguring my exhaust to basically make, right below my lights to the top of the tent, one giant light hood with an exhaust. The radiant heat put off by the lights is what hurts most of us with heat issues, even with cool tubes, but a 1/8th inch of plexi running the whole inside of the tent, the 4x8 piece would act like a cool hood in the sense eliminating any heat issues. It's fairly inexpensive for the sheet, about $90, and easily dripped and with some reinforcement, easily hung inside. A/C inlet remains in place, oscillating fans, etc., but just moving the scrubber for odor control down on the bottom inlet/outlet.
If I can clarify my idea, anymore.....or if you think it's not a "hot" idea, let me know!
