Greenhouse Fan

The Greenhouse Circulation Fan is vital to healthy plants in your greenhouse. They reduce heat stress and improve air quality. This is done by a gentle “racetrack” air pattern which mixes the air from the ceiling to the floor. You need to maintain air circulation so that temperatures remain uniform throughout the greenhouse during the winter when the greenhouse is heated. For those without electricity available at your greenhouse location, we now offer a solar powered circulation fan. Scroll down the page for more information on this product.

Features of Circulation Fans

Small fans with a cubic foot per minute air moving capacity equal to one quarter of the air volume of the greenhouse are sufficient. For small greenhouses, place the fans in diagonally opposite corners. If you have a larger greenhouse, you may need to place circulation fans at the halfway mark of the length. Also, you may need to place 4 across on the width. For most hobby greenhouses, one in each corner will be sufficient. Turn the circulation fans off during the warmest summer months when the greenhouse will be needed to be ventilated. An often overlooked item, the greenhouse circulating fan is a small investment for healthy plants.

These are also often referred to as HAF fans, horizontal air flow fans.
