When growing indoors, your grow room's ventilation is extremely important. Because most grow rooms or tents are enclosed and in tight quarters, without the right inline fan you’re looking at overheating your growing area and thus killing your plants. A variable speed fan gives you control over the intensity of its work therefore allowing you to control the temperature and humidity in your growbox or growing area. Resulting in a perfect environment for plants, their great apperance and health.
