Exhaust Fan CFM Calculation
Good air flow throughout your grow room is by far one of the most important aspects of indoor gardening. Plants need a constant supply of fresh air to achieve their maximum growing potential. Proper air exchange also helps to keep the temperature at optimal conditions to prevent any heat related stress on your plants. When choosing a fan remember that its better to have too much air circulation then not enough.
Also remember that if your going to be ducting your exhaust, with numerous bends, or running it through a carbon filter you'll need to increase your CFMs to makeup for those lost due to back pressure.
