Light-diffusing panels
The 8 mm twin-wall panels spread sunlight into an even glow instead of harsh beams, and you can't see inside from just 8" away.


The MONT – Growers Edition is the ideal greenhouse designed for crops that require a lot of light in a private and secure setting. The MONT is 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).
Proudly made in the USA. Our commercial electric exhaust fan system with built in louvers and commercial thermostat are all made in the USA and help control the temperature inside of your Monticello Greenhouse.
The Growers Edition is standard with our 8mm twin wall roof and wall panels that are light diffusing. These panels create a more even light flow into the greenhouse creating a glow instead of a light beam effect for more even light distribution for a longer period of time. The light diffusing panels also offer a higher level of privacy, just 8 inches away and you cannot see into the greenhouse. The panels are designed for crops that require an even light flow for long periods of time.
Other features included in this package including a folding work bench system, a drip irrigation system (customized up to 48 dripper heads) with programmable timer, and a 17,000 BTU commercial heater with built in thermostat, and dual automatic roof vent openers. For the avid grower, there are also optional Genesis LED grow light systems which cover a 4ft x 4ft section as well as an evaporative cooling system designed as air conditioning for our Growers Edition greenhouse.
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 MONT'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. You get what you pay for and with the Monticello this rings true.
We back the MONT with the strongest warranty in the industry (15 yrs.) on the frame and polycarbonate. For the gardener that is looking for a quality greenhouse system that will supply years of hassle free indoor gardening this is the greenhouse for you. We hope you enjoy growing in the MONT as much as we enjoyed designing it.

Free curbside freight delivery
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
We'll contact you to set up a delivery time frame that works for you.
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.
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.
