Solar Cooling Fan Upgrade

Twin-Wall (8mm) Polycarbonate Panels

Limited Availability Based on Geographic Region
Not Available on 33’ and 42’ Kits

We only recommend that you use twin wall glazing if your average minimum winter temperature is 15 to 20 °F, or warmer (USDA climate zone 8b or warmer) and require higher light transmission.

Windy Weather Package

The Windy Weather Package now comes standard on all Growing Domes

Reinforced vent openers and mounting brackets will keep your automated vent openers secure even in extreme winds.  We always recommend facing the vent hinges in the direction of the prevailing winds, but in many areas you don’t know which way the wind will be coming from.  Therefore we ship all Growing Domes with this package and/or Solar Attic Fans for improved reliability.
