Peace and Love to ALL

I have tried this and it will not work. I too had a heat problem. I also had an old fridge like you would see in a dorm room ,mini bar etc tec. I took a hole saw and cut a hole into the side and ran duct from the fridge to the cabinet,clost etc. The fridge door has to be open to allow any air to travel from the fridge to the grow room-Due to the seal when you close the door and it turns out like trying to suck an orange through a straw. Then with the door opened/or a little cracked the fridge will sweat and I mean sweat. So you have a fire hazard!! The fridge is also struggling to keep up with the temps changing so electricity usage actually increases with the pumps running 24/7.
STINKYATTIC ROCKS!!
You can go to Wally World and get yourself a 5000 BTU AC for $ 75-80. It will reward you for the money spent I guarantee. Just hook up the vent work coming from the ac to the grow area and play with the thermostat until you get your temps you want. The vents can be attached to the exhaust of the ac using duct tape. Just remember to not allow anything to block the incoming vent to the ac as it needs to keep cool. This was the only way I solved my heatproblem as well.:thumbsup:
