Re: Dutch Dragons OG Kush - Blueberry White - 2'x2' Cab - Batmix Soil Grow - 250 Watt
African Grower, I've only done this one run with this setup, but the fans are not affected by the heat. I'm prity sure they are designed to move hot and cold air around air conditioned ducting so I don't think there will be any issues. However, if you have a larger grow room than my two foot by two foot, you would be better off investing in a larger fan and filter setup for your cooltube. I started with just one fan, but it didn't cut it with the carbon filter rated at 190cfm, but after adding the second it is very affective. The end of the vent tube blows hot air like a fan heater. Cab temps are about 5 degrees Celsius above ambient room temp. Also, the exhaust vent from the cooltube to the exit of the box gets hot, so the pipe had to be insulated. I used a couple of layers of bubble wrap, but one of those acoustic insulated pipes would have been better. The insulation alone knocked off 5 degrees Celsius from the box.
