Delivered Complete Solar Gem Greenhouses require no assembly. The one-piece fiberglass greenhouse construction, gothic arch and ribbed design make our greenhouses super strong and yet remarkably light weight. These portable greenhouses are easy to move from one location to another. They have no seams for heat loss and no framework to rust, rot or panels to get loose from gusty winds and storms. The Easiest Way To Garden! Our ceiling vents and automatic ceiling vent openers are located at the top of the greenhouse preventing heat from getting trapped which allows for natural heat exhaust and eliminates the need for expensive fans. The glass fibers in the wall diffuse the light inside the greenhouse resulting in uniformly shaped plants and flowers, eliminates the need for turning or rotating of your plants, and allows for multiple level gardening. The Solar Gem Greenhouses will out produce any comparable size greenhouse on the market. No Foundation Required All you need to do is dig a 3 inch deep, 10 inch wide trench for the greenhouse to fit into and we do the rest. Our delivery crew will place the greenhouse into your yard right where you want it. Once the built-in foundation lip is back filled with dirt or gravel the greenhouse is secure. You then have natural drainage inside the greenhouse and you can plant directly into the ground if you want to. The 8' high ceiling is plenty high for tomato plants, lemon trees or most any tall plant. Gel Coat Exterior The Solar Gem Greenhouse is the only fiberglass greenhouse with a gel coat exterior. We use the highest quality marine grade gel coat on our greenhouses. Both the fiberglass interior and gel coat exterior are UV stabilized. So, unlike all other fiberglass greenhouses and fiberglass panels on the market, the Solar Gem Greenhouses will not pit or get rough on the outside. Our gel coat stays smooth for as long as you own the greenhouse and it does not discolor.
