Gary E. (Omaha, NE) (verified owner) –
We installed a small thermostatically controlled heater and kept tender starts warm during late frosts. Following the advice to assemble on a calm, windless day made installing the panels stress-free. Has completely elevated our gardening success and extended our season into the winter.

The roof vent opens smoothly to provide ventilation on warm afternoons, keeping temperatures balanced. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. Solid engineering and top notch materials throughout. Very happy with this purchase.
