Oscillating fans are commonly seen in homes during hot days to keep people cool. They can also be used in grow rooms to help bring the temperature down and circulate air in a grow room. They also help to simulate a breeze on plant limbs and branches, helping them to grow stronger. Inline fans are used mostly in ventilation, and create a powerful suction that can help draw fresh air into your grow room, or remove and/or filter old air out. We recommend using a combination of both oscillating fans and inline fans to maintain ideal control over the air quality of your grow room. JUMP TO GROW FANS
