Item Description

Not on greenhouses are built the same and the Riverstone Industries Monticello 8 x 20 ft. Premium Greenhouse Kit is here to prove it. A top-quality Monticello greenhouse, this one was proudly made in the USA. By applying good old American ingenuity, Monticello can make superior products and help elevate the industry standards of all greenhouses.

This premium greenhouse is built from the highest quality US-grade extruded aluminum and not the thinner and more brittle foreign aluminum. It features a protective coating that comes in two color options. The coating will not discolor over the years and is guaranteed to contain 0.0% lead. On average, this greenhouse uses over 85 pounds more aluminum than the typical imported greenhouse. Why is this important? A weaker framework suffers more wind damage and can handle less snow before collapsing.

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 uses professional-grade 8mm twin wall polycarbonate. This is the same thickness used in the commercial greenhouses. The twin wall polycarbonate acts as a double paned window keeping cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This makes the Monticello more efficient than other greenhouses. It also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year round.

The average greenhouse on the market today takes a full weekend to assemble. This is why many greenhouse owners say their top issue in the first two months of ownership is the actual set-up. Through a combination of using superior materials and creating interchangeable parts, the Monticello takes the average gardener 12 hours to assemble an 8 ft. x 20 ft. greenhouse with the premium package, while using fewer parts. This does not include the base prep work needed, which includes leveling the ground.

This is a premium package, which includes the Monticello greenhouse, one commercial work bench, interior shade system, programmable watering system, and the only greenhouse sink in the industry.

At 7.6 feet tall at its peak, the Monticello’s above average interior height helps displace heat within the greenhouse and is more comfortable for even the tallest gardeners.

This Monticello greenhouse is loaded with features to ensure you’ll enjoy it for years to come. Features include an integrated base, built-in rain water gutter system, and automatic roof vent opener. The newly redesigned hinged double doors have an opening of almost 6 feet tall by 4.5 feet wide! The Monticello grows as your needs do, with four-foot extension kits that can be purchased any time in the future.

You get what you pay for and with the Monticello! Monticello is backed by a 10-year warranty, one of the strongest in the industry. This warranty includes the frame and polycarbonate. 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.

We hope you enjoy growing in the Monticello as much as we enjoyed designing it.
