Serious Growing Demands a Serious Structure

The Monticello Greenhouse is built for homeowners who refuse to compromise on craftsmanship. Made in the USA from US-grade extruded aluminum, it uses roughly 40 lbs more material than imported alternatives — meaning it holds more snow and stands stronger through wind. Commercial-grade 8mm twin wall polycarbonate panels outperform the thin .2mm walls found on hobby models. This is a vetted, curated investment in your backyard that ships fully equipped with a workbench system, programmable watering, interior shade, and a sink system.

Riverstone Industries Monticello Premium Greenhouse – Mont-8-BK-Premium

Not all greenhouses are built the same and the Monticello line of greenhouses by Riverstone Industries proves this to be true. The Monticello is proudly made in the USA, applying good old American ingenuity to make the best product for our customers and help to elevate the industry standards of all greenhouses. Constructed from the highest quality extruded aluminum (US grade, not the thinner & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead), our greenhouse uses on average 40 lbs. more aluminum than the average imported greenhouse. Why is this important? The weaker the framework, the less snow the greenhouse can hold in the wintertime before collapsing on itself, also the easier it will get damaged in wind.

Riverstone Industries Monticello Premium Greenhouse

While most hobby greenhouses on the market use less expensive thinner walls and roofing materials (the crystal clear walls are as thin as .2mm), the Monticello Greenhouse uses professional grade 8mm twin wall polycarbonate. This is the same thickness as used in commercial greenhouses. The twin-wall polycarbonate acts as a double plane window keeping the cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This not only makes the Monticello Greenhouse more efficient to grow in for a longer period of time than other greenhouses, but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year-round.

This is a Premium Package, which includes the Monticello Greenhouse, one side of commercial workbenches, Interior Shade System, Programmable Watering System, and the only Greenhouse Sink in the Industry. From the integrated base to the built-in rainwater gutter system, to the automatic roof vent opener and the newly redesigned hinged double doors with an opening of almost 6ft high x 4 ft wide ensures your enjoyment of the Monticello Greenhouse for years to come.

You get what you pay for and with the Monticello Greenhouse, this rings true. The Monticello Greenhouse comes with a 10-year warranty on the frame and Polycarbonate, the strongest in the industry. For the gardener that is looking for a mid-priced greenhouse system that will supply years of hassle-free indoor gardening, this is the greenhouse for you.
