Testing out my new box today, I can't seem to get temperatures below 95*!
This is what I'm working with.
Dimensions are 22" wide, 14" deep, 28" tall. I've got a 120mm case fan (73cfm according to the package it came in) pushing the air from inside the box through a homemade carbon filter in the box in the upper right corner in the pic (yes the fan mounts to a piece of wood with a hole in it to seal up the box), and that box vents out the top via two 1 1/2" and one 1 5/8" holes (same surface area as the fan itself). For intake I have the same sized holes as the exhaust, only on the front panel along the bottom. The fan is certainly moving some air, even with the carbon filter in place theres a strong breeze coming from the exhaust holes, and the case is sealed up good and the passive intake design is working (according to the mini-bic lighter test).
The temp inside the box is above 90* when the lights and fans are on. (I have an 80mm fan blowing at the top 3 bulbs to keep the air moving around inside) For lights I tried five 40w'ers, and then I replaced two of those with 23w bulbs to see if that made a difference, and the temp stayed the same. Took the carbon filter out to see if it was causing too much restriction, but temps didn't go down.
I'm anxious to put this box to use, but I'm already having to deal with my PC case grow burning up 'cause of high temps, I don't want to jump into another grow without my temps being under control.
Any advice or suggesions? I was thinking about getting rid of the "exhaust box" (I figure its an easy way to house the carbon filter as well as keeping the light from being visible up top) and putting TWO 120mm fans on the top of the box with carbon filters hanging down into the box, with the fans pulling the air through. Do you think this would help? Any other suggestions? Thanks!
