maybe....but wont the heat just spread around the grow area....cool tube should be here tomorrow and right now the lights are off so i'll just wait....preciate the suggestion thoyou cant clip that fan and have it blow directly on your bulb????
i'm using 170cfm inline fan....got my cool tube setup and my temp is 82 and light is way closer to topsyeah i had to setup a ducting system for my 600w, now i see temps around 82-85*, plants are 5-15in under it. it's been better and worse, but plants are doing well.
what kind of fan are you going to use ?
