MONT 8x8 Greenhouse

The MONT 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 4ft) and the built-in rainwater gutter system ensure that you will be able to grow inside your MONT greenhouse for many years to come.

The best feature of all is that your MONT 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.

100% Made In The USAFact: When you buy a MONT Greenhouse you are buying a Greenhouse that is 100% Manufactured In The USA, by Riverstone Industries, using US Grade Aluminum. A MONT Greenhouse uses on average 40lbs more aluminum than the average imported greenhouse.

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.
