A too high humditiy in the greenhouse, is a significant problem in horticulture. It increases the risk of illness and infection of your crops. With recirculation fans you can bring an air flow in the greenhouse. This gentle air movement doesn’t just have a drying effect on the crops, which reduces the risk of illness; it also leads to an even temperature distribution in the greenhouse. This creates balanced growth for your crops. The fan speed can be regulated so you can control the air flow speed.
