I dont cool my lights at all because the temps are pretty mild in Western Washington so it stays around 80-85 degrees without me needing extra ventilation. I just have aluminum wing reflectors.

Its not really the bulbs that raise my grow room temperature, its my ballast! Remove you ballast from your grow room if you can because those things get realllllyy hot.

Im gunna gather some funds from this harvest and invest in another 600 watt Lumatek, a good can fan, carbon filter and two cool tubes. Probably $700 in improvements, but i know its gunna be worth it in the end. My ventilation isnt adequate and its starting to really smell. Summer is coming so i know that im gunna need to cool my bulbs and deal with the odor.
