Protects delicate young plants from aphids, neighborhood rabbits, and harsh hail storms. 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 anchoring base frame bolted securely into our perimeter timber foundation with heavy screws. The roof slope sheds rain quickly so there is never standing water or dirt accumulation on top. Has completely elevated our gardening success and extended our season into the winter.

Our spring seedlings have developed deep green foliage inside the protected environment of RIGA Greenhouse. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. Our seed starts have never been healthier. Highly recommended to all gardeners.

We hung hanging baskets of strawberries from the roof cross-members without any sagging. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Alexander Watson (Fort Wayne, IN) (verified owner) –
The polycarbonate sheets resist yellowing and retain their optical clarity season after season. The base profile is sturdy enough to step on without bending when walking through the doorway. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Catherine Keller (Grand Rapids, MI) (verified owner) –
No glass to break if an errant pebble flies from the lawn mower, making it very safe for pets. The packaging included spare nuts and bolts which came in handy during the roof truss build. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.
Eric & Nicole G. (verified owner) –
We added automated drip irrigation lines along the staging tables for effortless plant care. The roof vent hinge operates smoothly and allows excess humidity to escape on sunny mornings. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.
Hannah Gomez (Flagstaff, AZ) (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. Solid engineering and top notch materials throughout. Very happy with this purchase.
Gary Stewart (Madison, WI) (verified owner) –
The sliding door glides smoothly on its upper track and can be latched open on sunny days. The panels slide into continuous aluminum channels that lock them firmly against wind uplift. Four solid stars. Excellent growing environment once you get through the detailed assembly.
