Grow Year-Round with Zero Electrical Costs

This vetted Monticello Mojave Edition greenhouse brings true off-grid capability to your backyard. The solar-powered commercial ventilation system produces twice the power needed to run the fan at full capacity, with surplus for future lighting or heating. Pre-tinted roof panels eliminate the need for shade cloth, and automatic roof vents handle temperature control without intervention. Built from US-grade extruded aluminum with 8mm twin-wall polycarbonate, this is an investment in serious growing power that holds up to 24 lbs/sq. ft. snow load and 65 MPH winds.

At Grill Island, we vetted the Monticello Mojave Edition because it meets a standard big-box aisles can't match — US-grade extruded aluminum instead of brittle foreign metal, and a solar ventilation system engineered entirely in America. We sell what we'd put in our own backyard, and this greenhouse earns that bar. The off-grid commercial fan, exhaust louvers, and thermostat are all American-made. The solar panel produces more than double the power needed to run the fan at full capacity, with headroom for future lighting or heating. You won't find a floor associate at a chain store who can explain why 8mm twin-wall polycarbonate outlasts thinner panels. That's the curation gap we close.

A complete growing system, not just a frame

A complete growing system, not just a frame

The craftsmanship shows in the details. Pre-tinted roof panels eliminate the need for shade cloth, so temperature control stops being a guessing game. Automatic roof vents with built-in openers respond to heat without you lifting a finger. Inside, the commercial folding bench system gives you serious workspace, while the programmable watering system and outdoor sink turn routine maintenance into a streamlined process. The RSI Vegi-Bee mechanical pollinator handles the job that bees can't always reach in an enclosed space — especially valuable if your backyard pollinator traffic is inconsistent. Every component is designed to work together as an integrated system, not a collection of aftermarket add-ons bolted on after the fact.

Grow into it — your greenhouse scales with you

Grow into it — your greenhouse scales with you

This is an investment designed to outlast your first planting season. The Mojave Edition handles 24 pounds per square foot of snow load and withstands winds up to 65 MPH, so it stays solid through conditions that collapse lesser structures. The patent-pending twist-and-lock assembly means fewer parts and a more rigid build — no wobbly panels after the first storm. What matters for long-term planners is expandability: add 4-foot increments as your growing ambitions grow. Start with the 12-foot model and extend later without starting over. Dual rainwater gutters let you harvest runoff for irrigation, cutting water costs. Average yearly operating cost runs between $200 and $250 — a modest figure for year-round growing.

Riverstone Industries Monticello Solar Greenhouse – MONT-12-BK-Mojave

Monticello – Mojave Edition is the ideal warm weather-growing greenhouse. We have now added to the list of features an off the grid solar powered commercial grade ventilation system to the Monticello. This system will allow the owner to now have much better control of their growing environment with NO electrical costs.

Our commercial fan, exhaust lovers, and commercial thermostat are all made in the USA and our solar panel can produce more than 2 times the needed power to operate the fan at 100%, allowing for future options such as lighting and heating.

Riverstone Industries Monticello Solar Greenhouse

The Mojave Edition Greenhouse also now comes standard with pre-tinted roof panels and automatic roof vents. The benefit is both aesthetically pleasing and functional. No need for a shade cloth system and taking the guesswork out of temperature control.

The Mojave Edition Greenhouse is constructed from the highest quality extruded aluminum (US grade – not the thinner & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain no lead). Riverstone greenhouse uses on average 60 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.

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 Mojave Edition Greenhouse uses 8mm professional grade twin wall polycarbonate, which 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 Mojave Edition 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.

At 7′ 6″ tall at the peak, the Mojave’s higher than average interior height design helps with dissipating heat within the greenhouse while also allowing for the tallest gardeners to stand comfortably when working inside the greenhouse.

From the integrated base to the built-in rainwater gutter system, to the automatic roof vent opener and dual hinged doors with an opening of almost 6′ high x 4′ wide ensures that you will enjoy the Mojave Edition greenhouse for years to come.

The Mojave Edition Greenhouse offers the ability to grow when you are ready to expand with the 4ft Extension Kit that can be purchased anytime in the future. You get what you pay for and with the Mojave Edition, this rings true. Mojave Edition Greenhouse comes with a 10 year warranty on the frame and Polycarbonate, the strongest warranty in the industries. For the gardener who is looking for a quality greenhouse system that will supply years of hassle-free indoor gardening, this is the greenhouse for you.
