Riverstone Monticello Greenhouse 8x20 (101in x 247in)

Monticello Logo

The Monticello manufactured and produced by Riverstone Industries has an above-average interior height, going as high as 7ft 6in at its peak which greatly helps in displacing heat, while also allowing tall gardeners to stand straight up inside their greenhouse.

The automatic roof vent openers, the hinged double doors (6ft x 4.4ft) and the built-in rainwater gutter system ensure that you will be able to grow inside your Monticello greenhouse for many years to come. 

The best feature of all is that your Monticello Greenhouse is backed with the STRONGEST 10YR WARRANTY in the industry; covering not only your frame but also the Polycarbonate sidewalls and roof.

Are you looking for years of hassle-free indoor gardening? Are you looking for a commercial-grade greenhouse in a hobby greenhouse package? Then look no further because with Monticello you get it all.

Question: What does this mean for you as the owner?

Answer: It means you are getting a greenhouse that is constructed right here in the USA with the highest quality extruded aluminum, not the more brittle & thinner foreign aluminum. Remember, the weaker the framework the less snow and the less wind it can handle.

Fact: Instead of using the thinner less expensive roofing and wall materials(some as thin as .2mm) Riverstone Industries decided to use 8mm twin-wall Polycarbonate which is the same exact thickness used in commercial greenhouses.

Question: How does this benefit me?

Answer: You choose 8mm twin-wall Polycarbonate for the same reason you choose double pane windows. Because it keeps it cooler during the summer and warmer during the winter. Which in turn cuts down your electric bill, if you choose to grow year-round but also provides for a more efficient grow environment.

    Is the frame anodized?
    Yes & No. The aluminum frame is anodized. However, the black frame is electrostatically painted.

    Is the black paint powdercoated?
    No, the black paint is electrostatically applied which is stronger than powder coating. It is very difficult to scratch and should not fade dramatically. Riverstone Industries guarantees it for 10 years.

    Is the aluminum frame cooler than the black frame?
    Yes, the aluminum frame is on average about 7 degrees cooler than the black.

    Can the Monticello be attached to a concrete pad? If so what are the dimensions needed for the concrete pad?
    Yes, you can use a concrete pad. Riverstone Industries recommends that you add 3 - 4 inchs to the pad on all sides.

    For Example:The 8ft x 8ft(exact size of 8.1ft x 8.1ft) would need a concrete pad of 8.4ft x 8.4ft.

    Note: Riverstone Industries does not provide concrete screws, you will need to buy these from your local hardware store.
