The roof vent opens smoothly to provide ventilation on warm afternoons, keeping temperatures balanced. The sliding door rollers are adjustable so the door hangs plumb and moves with light finger pressure. An incredible investment for anyone who loves fresh garden vegetables and flowers.

An indispensable asset for anyone passionate about organic gardening and homesteading. The packaging included spare nuts and bolts which came in handy during the roof truss build. An incredible investment for anyone who loves fresh garden vegetables and flowers.

Peeling the protective UV film took some patience, but the panels underneath were pristine. The diffused light reaches the lower leaves of tall plants, promoting even, bushy growth. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.

Protects delicate young plants from aphids, neighborhood rabbits, and harsh hail storms. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. Solid engineering and top notch materials throughout. Very happy with this purchase.

A beautiful architectural addition to our backyard that looks like a miniature conservatory. The roof slope sheds rain quickly so there is never standing water or dirt accumulation on top. Four solid stars. Excellent growing environment once you get through the detailed assembly.
Hannah Garcia (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. An incredible investment for anyone who loves fresh garden vegetables and flowers.

Our heirloom tomatoes and sweet peppers are thriving inside Riverstone MONT Greenhouse this season. The diffused light reaches the lower leaves of tall plants, promoting even, bushy growth. 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 clear side panels provide maximum solar gain while the opaque roof prevents leaf burn. Has completely elevated our gardening success and extended our season into the winter.

We enjoy spending weekend mornings potting herbs and listening to music inside. The headroom along the center ridge beam allows comfortable standing even for taller gardeners. Solid engineering and top notch materials throughout. Very happy with this purchase. Solid construction that will last for years.

We set up Riverstone MONT Greenhouse on a leveled pressure-treated base and it has transformed our gardening hobby. The panels slide into continuous aluminum channels that lock them firmly against wind uplift. Our seed starts have never been healthier. Highly recommended to all gardeners.
