Our vegetable yield has doubled compared to planting directly in the exposed garden soil. The aluminum frame bolted together rigidly once all the corner brace gussets were secured. Solid engineering and top notch materials throughout. Very happy with this purchase.

We installed a small thermostatically controlled heater and kept tender starts warm during late frosts. 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.

We set up Riverstone MONT Greenhouse on a leveled pressure-treated base and it has transformed our gardening hobby. The base profile is sturdy enough to step on without bending when walking through the doorway. Solid engineering and top notch materials throughout. Very happy with this purchase.

The twin-wall polycarbonate panels diffuse the strong midday sun so delicate seedlings never scorch. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. Four solid stars. Excellent growing environment once you get through the detailed assembly.
Carol C. (verified owner) –
The polycarbonate sheets resist yellowing and retain their optical clarity season after season. The packaging included spare nuts and bolts which came in handy during the roof truss build. Be sure to assemble on a windless day to make panel installation easy. Very solid result.

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. Our seed starts have never been healthier. Highly recommended to all gardeners.

The twin-wall polycarbonate softens harsh sunlight while holding daytime warmth overnight. Following the advice to assemble on a calm, windless day made installing the panels stress-free. Four solid stars. Excellent growing environment once you get through the detailed assembly.

The integrated rain gutters along the eaves make it effortless to collect rainwater for the plants. The door handle latches securely in both the fully closed and partially cracked ventilation positions. Our seed starts have never been healthier. Highly recommended to all gardeners.
Dustin Chavez (verified owner) –
Sliding the polycarbonate panels into the channel tracks was straightforward using soapy water. We mounted thermometer sensors at canopy height and bench height to track temperature gradients. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Daniel White (Coeur d’Alene, ID) (verified owner) –
The gutters channel every drop of rain straight into our rain collection barrel. 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.
