Joe and I purchased a portable greenhouse kit right before New Year’s Eve. We also purchased several bags of top soil and river rock to condition the site where we planned to install the greenhouse.
The greenhouse consists of two main parts — 1. A galvanized steel frame (assembly required) and 2. A mesh cover which fits over the frame like a tent. We assembled the frame in stages in our driveway.
We added river rocks and large rocks around the exterior of the greenhouse so it would blend into the existing landscape. We will add some ornamental grasses in the spring to help beautify the installation and blend it into our potager garden.
We have been very satisfied with the durability and integrity of the frame, cover, and anchor brackets (with updated stakes). The greenhouse survived two major snowstorms that dumped 10 inches (early January) and 7+ inches (last night) within a 24-hour period. It’s easy to clear the snow off by gently prodding the ceiling from inside the greenhouse. We use a small broom. The snow slides easily off the exterior walls of the cover.
The greenhouse is quite roomy inside — the dimensions are 78-3/4 in. L x 118 in. H x 84 in. W. We are mainly using the greenhouse to grow microgreens, but will also use it to start vegetable and herb seedlings for the garden. We purchased some shelving units to hold the microgreen trays.
Arctic temperatures (due to the polar vortex phenomenon) have been challenging. Our initial trays of microgreens frosted over and failed to germinate. We purchased a space heater to maintain temperatures above freezing. The space heater keeps up with external temperatures down to about 15 F. but the soil frosts over when it drops below that.
