Weather Packages

Desert Heat Package – $550

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 Desert Heat Package for your Growing Dome. This package for our small solar greenhouse kits adds an extra Solar Powered Cooling Fan for extra ventilation and cooling and utilizes the evaporative cooling effects of a full-surround Misting System that easily connects to your garden hose.

System Upgrades

Solar Powered Waterfall – $250

The solar powered waterfall for the 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 our year round greenhouses. View Growing Spaces video of our pond with a solar powered waterfall.

Drip Edge Flashing – $245

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 – $190

The strut on the foundation wall of the geodesic greenhouse that lays flat against the ground is termed a “bottom plate”. Growing Spaces’ small greenhouses come standard with a treated ProWood bottom plate. ProWood is a safe 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 – $400

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.
