My other hoods were not vented and run a atlas 1 controller. The acde hoods stay cool to the touch even when temps reach into the 90s the glass is hot. Using 8" ducting with a vortex s line fan with a speed controller.Right but your other hood more than likely leaked the same amount. There for no change would be noticed. I have a titan Atlas 5 hand held co2/humidity/temp sensor. Every room with air cooled hoods that I have been in leak. Some more than others. I however have not tested a room with the ACDE hood. I have looked closely at them. Well built just like every sun system product. I think the main issue is in the entire concept of Air cooled lighting is counter-intuitive. When temps out side rise the effiency of air cooling takes a nose dive. You have to pull air from some where. Even if its cool basement air that air is still being pulled in to the basement from somewhere most likely outside. I think once more people grasp and also unfortunately fork out a little more doe to build proper sealed rooms the quality of cannabis available everywhere will be un-real.
What was the damage?Just picked up a pro 1000e DE, in Michigan nonetheless.
