Collection: MONT (Monticello)

MONT greenhouses (Monticello by Riverstone) are an affordable entry into a solid, long-lasting greenhouse. They use twin-wall polycarbonate, a sturdy aluminum frame, and straightforward assembly. If you want reliable growing space without the premium price of glass or high-insulation models, MONT delivers.

MONT sizes and styles

Standard Monticello: sizes from 8 × 12 ft to 10 × 24 ft. Aluminum frame, twin-wall polycarbonate, hinged doors, automatic roof windows.
Monticello Mojave: the same greenhouse in a desert theme with a unique silhouette and slightly different window placement.
Growers Edition: built for commercial use, with upgraded foundations, heavy-duty hinges, and the longest warranty in the MONT line.

Why choose MONT?

You get a greenhouse that will last 15–20+ years with minimal upkeep. Aluminum does not rot, polycarbonate does not crack easily, and the design is simple enough that assembly is straightforward. It is not the insulation of a Riga or the beauty of a Victorian, but for growers who want solid, honest value, MONT is hard to beat. Many owners keep them running for two decades.

MONT FAQ

Is MONT good in snow country?

The frame handles snow well. Twin-wall polycarbonate loses more heat than insulated glass or thick polycarbonate, so you will need a heater if you grow through winter in cold areas.

How long does MONT last?

With normal care, 15–20+ years. Aluminum does not rot; polycarbonate yellows slightly over time but remains functional. It is one of the strongest warranties in the industry.
