| _____________________________________________________________ |
| On warm or sunny days, our Exhaust Fan automatically removes excess heat from your Northern Light, American Harvest, Grow House, or Garden Starter Greenhouse and draws in cool, fresh air. This increases carbon dioxide levels, helps to maintain uniform temperatures, and controls humidity-related plant diseases. Each fan comes with a moisture resistant thermostat for automated on/off control. It is fitted with a safety guard on the inside, and automatic aluminum shutters on the outside. Weve taken all the hard work out of installation by providing a corrosion-proof mounting frame, stainless steel fasteners, and complete instructions. All fans run on standard household electrical current. Some wiring required. Wire not included. Ventilation requirements depend on the size of your greenhouse and your local climate. |
