Riverstone Mont Greenhouse 8x8

Riverstone, RSI, Monticello, greenhouse, outdoor structure, blackNot all greenhouses are built the same and the Mont line of greenhouses by Riverstone Industries proves this to be true. The Mont is proudly made in the USA. 

Constructed from the highest quality extruded aluminum (US grade - not the thinner & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead), our greenhouse uses on average more than 40 lbs. 

 Riverstone, RSI, Monticello, greenhouse, outdoor structure, blackThis 8mm twin wall polycarbonate is the same thickness as used in the commercial greenhouses. The twin wall polycarbonate acts as a double pain window keeping cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This not only makes the Mont more efficient to grow in for a longer period of time than other greenhouses but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year round.

At 7ft 6in tall at the peak the Monticello's above average interior height design also helps with displacing heat within the greenhouse while also allowing for the tallest gardeners not to have to bend down when inside the greenhouse.

From the integrated base to the built in rain water gutter system, to the automatic roof vent opener and the newly redesigned hinged double doors with an opening of almost 6ft high x 4 & ½ft wide ensures you are sure to enjoy the Monticello greenhouse for years to come.



🌿 Proudly designed and made in the USA

The bench will hold up to 600 lbs. The sturdy vented shelving units on the Work Station are constructed from commercial grade high impact PVC. The vents allow water and air to circulate as well as allowing sunlight to reach underneath the Work Bench.  The Work Station can be installed either during initial construction or at a later time. The Kit Includes a full 8 ft run (24” deep) for use on either side of the Monticello greenhouse. Since the installation of the support bars uses the inside bolt tracks the shelving could be set at any height within the greenhouse (up to 4ft off the ground). 
    • 🌳  Monticello interior shading Cloths:  The design is simple, unique and thoughtful. The Monticello Shade Cloth kit comes ready to use, no grommet installation needed. The commercial grade shade cloth (rated at 63%) works off a specially designed commercial grade wire system guaranteed to last for 7 years. The shade cloth comes in 4 foot sections. To operate the Shade Cloth System is as easy as pulling the cloth back to open or pulling tight to the other side to close. 
    • 🌳  Monticello programmable watering system:  The Commercial grade system is similar to those used by professional growers. The Automatic Greenhouse Watering System is designed to be hung from the ceiling of the greenhouse. The 1 weighted sprinkler heads are separated by 4ft spray in a circular pattern. The Commercial digital timer is designed to allow for customer watering cycles based on climate and time of year. 
    • 🌳  Monticello greenhouse potting sink

Overview

The MONT proves that not all greenhouses are built the same. Riverstone Industries makes it in the USA from heavy-duty, US-grade extruded aluminum, electrostatically painted black with paint guaranteed to contain 0.0% lead.

The walls and roof are 8 mm twin-wall polycarbonate, the same thickness used in commercial greenhouses. Like a double-pane window, it keeps cooler air in during warm months and insulates against cold air in winter, so you can grow for longer and spend less on electricity if you grow year-round.

At 7' 6" tall at the peak, there is room for tall gardeners to work without bending, and the extra height helps move heat away from your plants. An integrated base, a built-in rainwater gutter system, one automatic roof vent and redesigned hinged double doors round it out.

Our tip: Need more room later? The MONT grows with you: a 4' extension kit (4' x 8' x 7' 6") adds length to your greenhouse.

How delivery works

  1. 1

    You place your order

    Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.

  2. 2

    We call to schedule

    We'll contact you to set up a delivery time frame that works for you.

  3. 3

    Free curbside freight

    Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.

  4. 4

    Receive and unload

    Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.

Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.
