Exhaust Fans and Filters

Temperature control is a must in any grow room.

Grow lights can generate too much heat to be healthy for your plants. An exhaust fan can help remove the heat buildup and circulate the grow room air to prevent overheating.

If you need ducting, clamps, flanges or other parts to connect your fans and filters together, find them here.
