Do you love plants? Do they grow better with a little help from us? Then, building your own greenhouse is the perfect way to ensure that all beautiful crops are safe and growing to their full potential.

This large commercial greenhouse is perfect for larger projects. In addition, Mont's Mojave Greenhouse Edition includes an off-the-grid solar-powered ventilation system that provides high-impact UV light with no electrical costs or hassle, giving owners much better control of their growing environment!

The Mojave edition also comes with standard pre-tinted roof panels and automatic roof vents that will surely benefit your greenhouse by looking aesthetically pleasing and functional. There is no more need for our shade cloth system and taking the guesswork out of temperature control.

Why do you need a Mont 8ft x 12ft Black Finish: Mojave Greenhouse?

The Mont 8ft x 12ft black finish greenhouse is proudly made in the United States. It is ideal for warm-weather growing commercial projects. It has a commercial exhaust fan, thermostat, and solar panel that can produce more than two times the needed power to operate the fan at 100%, allowing for future options such as lighting and heating. It is equipped with a built-in and integrated rainwater gutter system, allowing your greenhouse to have an independent support system for growing crops. It is stable, and it has professional-grade 8mm twin-wall covers for walls and roof that has the same thickness as used in commercial greenhouses nowadays. 

Our goal is to ensure you have the type of greenhouse you want. Extruded from 60lbs aluminum, or US grade aluminum, not the thinner, brittle foreign aluminum. It is electrostatically painted black and guaranteed not to contain any lead. Furthermore, since it uses twin-wall polycarbonate, it will act as a double pain window keeping cooler air in warm months and insulating the greenhouse from the cold winter air.

The frame, walls, and roof are warranted for ten years, and it is mid-priced, which is perfect for gardeners on a budget. The Mont Black has 7ft and 6in tall peak walls that prevent the gardener from bending down inside the greenhouse. In addition, Mont extends the crops from growing up to 4ft because it has an extension kit that you can purchase anytime soon.
