The crystal clear side walls give us full visibility into our plants from the kitchen window. 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.

We hung hanging baskets of strawberries from the roof cross-members without any sagging. The clear side panels provide maximum solar gain while the opaque roof prevents leaf burn. Our seed starts have never been healthier. Highly recommended to all gardeners.
Joyce Schmidt (verified owner) –
We enjoy spending weekend mornings potting herbs and listening to music inside. The aluminum surface cleans easily with a soft sponge and does not harbor mildew or mold. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Rebecca Holloway (Appleton, WI) (verified owner) –
The structure was easy to square using the diagonal corner measurement technique in the manual. The aluminum frame bolted together rigidly once all the corner brace gussets were secured. Take your time leveling your foundation timbers and the frame will square up nicely.
Edward Davis (Kansas City, MO) (verified owner) –
The automatic vent arm we added opens by itself as the sun warms up the interior. The twin-wall polycarbonate cushions heavy downpours so the noise level inside is pleasant. Our seed starts have never been healthier. Highly recommended to all gardeners.
Jeff & Amy Murphy (verified owner) –
The greenhouse holds solar heat remarkably well, staying ten degrees warmer than the outside air at dusk. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Anthony Nelson (Lancaster, PA) (verified owner) –
Our vegetable yield has doubled compared to planting directly in the exposed garden soil. 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.
Sarah Schultz (verified owner) –
We installed a small thermostatically controlled heater and kept tender starts warm during late frosts. The packaging included spare nuts and bolts which came in handy during the roof truss build. Has completely elevated our gardening success and extended our season into the winter.

The twin-wall polycarbonate softens harsh sunlight while holding daytime warmth overnight. The structural cross-ties provided handy mounting points for our grow lights and small circulation fans. Solid engineering and top notch materials throughout. Very happy with this purchase. Glad we chose this model over the alternatives.

No glass to break if an errant pebble flies from the lawn mower, making it very safe for pets. The base profile is sturdy enough to step on without bending when walking through the doorway. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.
