MONT Greenhouses Provide Years of Hassle-Free Indoor Gardening

  • Ships directly from supplier
  • Extended frame height displaces heat and accommodates taller gardeners
  • Features integrated base and rain gutter system
  • Hinged double-doors allow easy transport in and out of greenhouse
  • Best-in-industry 10 year warranty on frame and polycarbonate

Not all greenhouses are built the same. With the MONT line of greenhouses by Riverstone Industries (formerly known as Monticello Greenhouses), we applied good old American ingenuity to make a higher-quality product for our customers and elevate the standards for what a greenhouse can be. 

Constructed from the highest quality extruded U.S.-grade aluminum, the frame of this MONT greenhouse uses, on average, 85 lbs. more aluminum than the typical imported greenhouse. Why is that important? Our stronger framework means MONT greenhouses can handle higher winds and hold more snow without damage. For walls and roofing, MONT greenhouses use professional-grade 8mm twin wall polycarbonate (the same thickness used in commercial greenhouses), which provides greater insulation, extending your grow season and increasing energy-efficiency for year-round growers.

If you’re 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 MONT greenhouses as much as we enjoyed designing them.

Note: Allow for a FULL weekend to fully assemble greenhouse (ground prep NOT included). Two people suggested for assembly. Actual time to construct will depend on size of greenhouse and skill levels.
