Not all greenhouses are created equal, and the MONT Standard Greenhouse Kit by Riverstone Industries proves this with premium American craftsmanship and superior materials. Proudly made in the USA, this greenhouse raises the bar by using high-quality extruded aluminum and thick, durable glazing, setting new standards in strength and longevity.

Built from robust extruded aluminum and electrostatically painted black (guaranteed 0.0% lead), the MONT Standard greenhouse uses approximately 40 lbs more aluminum than imported alternatives. This stronger frame allows for greater snow load capacity during winter and superior wind resistance, preventing structural damage over time.

Unlike many hobby greenhouses that use thin and fragile walls (as thin as 0.2mm), the MONT Standard features professional-grade 8mm twin-wall polycarbonate panels—the same thickness found in commercial greenhouses. These panels provide excellent insulation by trapping cooler air in summer and retaining heat in winter, enabling extended growing seasons and year-round gardening.

With a peak interior height of 7 ft 6 in, this greenhouse’s tall design helps dissipate heat efficiently and provides comfortable standing room for gardeners of all heights. Key features such as an integrated flush base, built-in rainwater gutter system, automatic roof vent opener, and redesigned hinged double doors (nearly 6 ft high by 4 ft wide) ensure convenience and durability.

The MONT Standard also offers modular growth with an optional 4 ft extension kit available for purchase anytime, allowing your greenhouse to expand as your gardening needs evolve.

Backed by a strong 10-year warranty on both frame and polycarbonate panels, the MONT Standard Greenhouse is an ideal mid-priced option for gardeners seeking long-term reliability and hassle-free indoor gardening.
