Weather Packages

Desert Heat Package – $440.00

1.Do you live in a desert or semi-desert climate (i.e. hot climate with low humidity)?
2.Do temperatures get above 95° F on a regular basis?

If you can answer “Yes” to any of these questions, then we highly recommend the 33 ft. greenhouse kit Desert Heat Package.
This package for our solar greenhouse kit adds an additional cooling fan to for extra ventilation and cooling and utilizes the evaporative cooling effects of a full-surround Misting System that easily connects to your garden hose.

* Do you live in a hot, humid climate? Contact us at 800-753-9333 to discuss what things you can do to have the Growing Dome work as a year round greenhouse where you live.

System Upgrades

Solar Powered Waterfall – $250.00

The solar powered waterfall for the 33 ft. greenhouse kit provides aeration for the pond which the fish enjoy and helps to slow down algae formation. Even better, it creates a wonderful ambiance inside the Growing Dome. View video of our pond with a solar powered waterfall.

Metal Glazing Strips Upgrade – $750.00

Rather than using the clear aircraft tape that comes standard with the Growing Dome Classic Kit to seal the seams between the polycarbonate glazing panels, the Metal Glazing Strips Upgrade includes a strong roofing tape covered by custom built aluminum strips to seal the seams of the geodesic green houses. After 10+ years of use on our Growing Domes we have found this upgrade provides a longer lasting, lower maintenance option for sealing.

Drip Edge Flashing – $145.00

This Drip Edge Flashing protects the wood on the inside of the top of your foundation wall from moisture and long-term degradation. There can, at times, be enough condensation accumulate to have water or ice sitting on the top plate of the greenhouse foundation wall for prolonged periods of time. Over the years this can degrade your wood despite having the best wood treatment possible initially applied to the wood. This custom cut and bent metal flashing installs right over your top plate.

Redwood Bottom Plate – $160.00

The strut on the foundation wall of the greenhouse that lays flat against the ground is termed a “bottom plate”. Our 33 ft. greenhouse kits come with a treated ProWood bottom plate. ProWood is a safer alternative to traditional pressure treated lumber, but some gardeners preferred to go with no treatment at all. For this reason we offer an upgrade to an untreated Redwood Bottom Plate that is resistant to decay for many years.

Solar Powered Cooling Upgrade – $300.00

The Solar Powered Cooling Upgrade for our four season greenhouses is the perfect option when saving money and being “off-grid” is of primary importance and/or when electricity is not available at the Growing Dome site. If you choose this upgrade along with the Desert Heat Package your additional fan will be solar powered.

Extra Door for Communities & Schools – $400.00

Oftentimes, the 33 ft greenhouse kits are built in a community space where the flow of human traffic needs to be optimized. An extra door for the Growing Dome really helps move classes and groups through efficiently. The extra door is also extremely helpful with cross ventilation in warm climates.
