Customization & Raised Bed Options

Customize your Growing Dome to match the look and feel of your house or neighborhood.  Both the 24″ external siding and the door can be designed to suit your landscape.  Also, the 24” foundation wall creates a natural base for external raised beds. You can customize your internal garden beds to maximize plant production, or get creative and design an extra space as a garden getaway.

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 vents in the direction of the prevalent 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.
