Energy-Saving Whole House Fan for Hydroponic Growers
The QuietCool QC ES-3100 whole house fan delivers 3,103 CFM of airflow at only 264 watts, giving hydroponic growers an ultra-efficient way to dump heat and humidity without running energy-hungry A/C all day. Its ECM motor delivers about 11.75 CFM per watt, making it one of the most energy-conscious house fans for growers who need strong ventilation on a budget.
Whole House Fan Cooling for Greenhouses & Grow Rooms
Covering up to 1,550 square feet, this unit works perfectly as a central greenhouse fan or paired with smaller inline fans for precise zone control in multi-room hydroponic setups and fans for greenhouses. The 16" x 24" grille fits cleanly between standard joists, while the required 4.1 sq. ft. of attic venting ensures that hot, stale air is quickly exhausted to protect plants, equipment, and nutrient solutions. Use it as one of your main ventilation fans for greenhouses or indoor gardens to keep temperatures stable and CO₂-rich air moving through the canopy.
Key features:
-
High airflow for large grow areas – 3,103 CFM moves hot, humid air out quickly in homes, greenhouses, or large indoor grow rooms up to 1,550 sq. ft.
-
Energy-efficient climate control – Only 264 watts at ~11.75 CFM/watt helps reduce A/C run time and lower electricity bills in hydroponic operations.
-
Great for multi-zone setups – Works excellently alongside smaller inline or oscillating fans to create targeted zone control across veg, flower, and drying rooms.
-
Improved plant health – Strong, continuous air exchange helps manage heat, humidity, and odors, reducing disease pressure and keeping CO₂ levels more consistent.
-
Clean installation footprint – 16" x 24" grille and attic-mounted fan free up floor space in grow areas for reservoirs, tables, and equipment.
-
Optimized exhaust path – Designed to work with 4.1 sq. ft. of attic venting so hot air leaves the structure efficiently, protecting both plants and building materials.
