Riverstone | MONT Premium Greenhouse Kit Package with 8mm Twin-wall Polycarbonate Glazing

Not all greenhouses are created equal, and the MONT line by Riverstone Industries proves it with superior construction and lasting performance. Proudly made in the USA, the MONT Greenhouse embodies American ingenuity and quality, setting a high standard in the greenhouse industry.

Crafted from high-grade extruded aluminum (U.S. standard, not brittle imported types) and electrostatically painted black with a 0.0% lead guarantee, this greenhouse frame uses on average 40 lbs more aluminum than typical imported greenhouses. This extra strength translates to greater snow load capacity and wind resistance, protecting your investment through harsh seasons.

Unlike most hobby greenhouses that use thin (.2mm) walls, the MONT uses professional-grade 8mm twin-wall polycarbonate panels—the same thickness used in commercial greenhouses. These panels form an insulating double window that keeps your greenhouse cooler in summer and warmer in winter, extending your growing season with enhanced energy efficiency.

The Premium Package includes the MONT greenhouse structure, a commercial-grade workbench system, interior shade system, programmable watering system, and the industry’s only greenhouse sink system. Additional thoughtful features include an integrated flush base, built-in rainwater gutters, automatic roof vent openers, and redesigned hinged lockable double doors measuring nearly 6 ft high by 4 ft wide for easy access.

This greenhouse grows with your needs—expandable in 4 ft increments with optional extension kits. Backed by a strong 10-year warranty on the frame and polycarbonate panels (industry-leading), the MONT Premium Greenhouse is the ideal mid-priced solution for gardeners seeking hassle-free, long-lasting indoor growing.

Allow for a FULL weekend to fully assemble (ground prep NOT included). Two people suggested for assembly. Actual time to construct will depend on size of the greenhouse and skill levels. Manual is fully illustrated.
