Alright guys here it is. Of course the only problem we have run into is heat. Temperatures stay at 88 right now with a 170 CFM 4" fan going over the 1000w cooltube light. Currently only a 4" hole as intake but i think ill add a small 4" homedepot inline fan to possibly bring down temps. What else could i do? Is the carbon filter in a shitty spot to be pulling air?

The box is 2x3x6.5 inside of my walk in closet. The end of the cooltube is were it exhausts out of the grow box.

Right now i have my oscillating fan pushing air up just so that hot air gets out a little better for now.

You need to get a bigger exuaust fan 4 sure. At least 6in 450cfm. The more your ducting bends the more flow is reduced, so try to keep it straight and short. Run your lights at night so you utilize the cooler air. Make sure room is light proof and let them sleep in the afternoon when outside temp is highest. Looks like a moisture meter might be in order, leaves look a littrle droopy. cheap. Good luck! Filter is in a good spot. turn it around so as to lose the s shape in your ducting. Word

any other input? I think i could work with the 4" inline fan as long as i get some more intake in there. When the fan blows on the canopy it stays aroiund 85

I have them same temp/RH gauge. I can see yours says 20% which is half of what you really need.



Also is looks as if your fan just blows into the reflector?

If thats the case you need that fan to be pulling air out of your cloest. A 1000 is a bit over kill for that small space. A 600 would be more than enough.

After re-reading your first post I realized yousaid it blows out the other end of the cool tube, my bad.

Yeah it pulls the cool air over the tube. I think the issue is the carbon filter is pulling air above the hood, so if i had a fan pushing some air in the bottom for intake, it could push colder air over the bulb and cool it efficently. I would rather not go for a 600w, even tho it is a small ass space. 1000w on 6 plants will make beautifully dense buds :). Other suggestions for cooling? Any energy efficent small ac units to keep it at 75?
