Our vegetable yield has doubled compared to planting directly in the exposed garden soil. Following the advice to assemble on a calm, windless day made installing the panels stress-free. An incredible investment for anyone who loves fresh garden vegetables and flowers.

The roof vent opens with a smooth action to allow natural air circulation on warm days. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.

The cathedral ceiling gives generous standing headroom so I never have to hunch while potting plants. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. Take your time leveling your foundation timbers and the frame will square up nicely.

We installed a small thermostatically controlled heater and kept tender starts warm during late frosts. The twin-wall polycarbonate cushions heavy downpours so the noise level inside is pleasant. Solid engineering and top notch materials throughout. Very happy with this purchase.

Freight delivery was prompt and the aluminum extrusions were packed securely in long boxes. 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.
William Bauer (verified owner) –
The corner gussets and roof braces give the entire structure impressive snow and wind resistance. The roof slope sheds rain quickly so there is never standing water or dirt accumulation on top. An incredible investment for anyone who loves fresh garden vegetables and flowers.
Ashley L. (Duluth, MN) (verified owner) –
The polycarbonate panels survived golf-ball-sized hail without cracking or denting. The base profile is sturdy enough to step on without bending when walking through the doorway. Four solid stars. Excellent growing environment once you get through the detailed assembly.
Dustin Reyes (verified owner) –
Our early spring seed germination rate reached nearly 95 percent inside this protected space. The clear side panels provide maximum solar gain while the opaque roof prevents leaf burn. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Jordan Nguyen (verified owner) –
The twin-wall polycarbonate softens harsh sunlight while holding daytime warmth overnight. The aluminum frame bolted together rigidly once all the corner brace gussets were secured. An incredible investment for anyone who loves fresh garden vegetables and flowers.

We assembled this greenhouse on a level treated timber foundation with pea gravel flooring. The roof vent hinge operates smoothly and allows excess humidity to escape on sunny mornings. Our seed starts have never been healthier. Highly recommended to all gardeners.
