Freight delivery was prompt and the aluminum extrusions were packed securely in long boxes. The panels slide into continuous aluminum channels that lock them firmly against wind uplift. An incredible investment for anyone who loves fresh garden vegetables and flowers.
Patricia S. (Greenville, SC) (verified owner) –
Our early spring seed germination rate reached nearly 95 percent inside this protected space. The sliding door rollers are adjustable so the door hangs plumb and moves with light finger pressure. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Jacob G. (verified owner) –
The greenhouse survived an unexpected spring hail storm with zero damage to the roof panels. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. Has completely elevated our gardening success and extended our season into the winter.
Daniel Hoffman (verified owner) –
We assembled this greenhouse on a level treated timber foundation with pea gravel flooring. The hardware pack was cleanly organized and the hex bolts tightened down without stripping. Our seed starts have never been healthier. Highly recommended to all gardeners.
Trevor Martin (verified owner) –
The roof vent opens smoothly to provide ventilation on warm afternoons, keeping temperatures balanced. The roof slope sheds rain quickly so there is never standing water or dirt accumulation on top. Take your time leveling your foundation timbers and the frame will square up nicely.
Jeffrey E. (verified owner) –
No glass to break if an errant pebble flies from the lawn mower, making it very safe for pets. The structural cross-ties provided handy mounting points for our grow lights and small circulation fans. An incredible investment for anyone who loves fresh garden vegetables and flowers.
Lance Jackson (Eugene, OR) (verified owner) –
The twin-wall polycarbonate panels diffuse the strong midday sun so delicate seedlings never scorch. The door handle latches securely in both the fully closed and partially cracked ventilation positions. Has completely elevated our gardening success and extended our season into the winter.
Daniel P. (Kansas City, MO) (verified owner) –
Our vegetable yield has doubled compared to planting directly in the exposed garden soil. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. An incredible investment for anyone who loves fresh garden vegetables and flowers.
Jose Reed (verified owner) –
The humidity levels stay consistent, creating an ideal microclimate for tropical house plants. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. An incredible investment for anyone who loves fresh garden vegetables and flowers.
Kathleen Ruiz (Des Moines, IA) (verified owner) –
The corner base clips anchored the greenhouse rigidly to our foundation timbers. The roof vent hinge operates smoothly and allows excess humidity to escape on sunny mornings. Take your time leveling your foundation timbers and the frame will square up nicely.
