The MONT Greenhouse is a robust, practical solution designed with the dedicated gardener in mind. Made in the USA, this premium greenhouse is designed to elevate your gardening experience to new heights, combining strength, functionality, and versatility in one package.
Whether you’re an experienced green thumb or an enthusiastic beginner, the Riverstone MONT Greenhouse is engineered to enhance your growing season, offering a versatile space where plants can flourish.
Just a heads-up: MONT used to go by the name Monticello. That’s right – the name got spruced up, but the greenhouses are still the same (or improved) garden havens you know and cherish. If Monticello Greenhouse rings a bell, you’re in the right place; welcome to the new era of MONT!
Key Features & Benefits of the Riverstone MONT Greenhouse
Versatile Sizing: Available in sizes ranging from 8′ x 8′ to 8′ x 24′, the MONT Greenhouse can accommodate gardens of various scales. Plus, it’s designed to expand in 4-foot sections, providing flexibility as your greenhouse gardening needs grow.
US-Grade Construction: Opting for a MONT Greenhouse means choosing a product that’s built right here in the USA with the highest quality extruded aluminum – using 40 lbs more than what’s found in the average imported greenhouse.
This superior construction ensures you receive a greenhouse far more robust than those made with the brittle and thinner aluminum commonly used abroad. Such strength is crucial, as a sturdier framework is better equipped to handle heavier snow loads and withstand stronger winds.
Each MONT Greenhouse is finished with an electrostatic paint for exceptional weather resistance, offering a level of durability and reliability that secures your gardening projects against the elements.
When you select a MONT Greenhouse, you’re not just buying a structure; you’re investing in a resilient haven for your plants, crafted to offer enduring support through every season.
Easy Setup: The greenhouse features an integrated base, allowing for straightforward setup on any level surface without the need for pouring concrete, simplifying the installation process (and reducing the installation cost).
Advanced Polycarbonate Glazing: The MONT Greenhouse distinguishes itself with its 8mm twin-wall polycarbonate glazing, a feature inspired by commercial greenhouse standards for unmatched durability and climate control. While others may opt for thinner, less costly materials, Riverstone Industries commits to this robust thickness to ensure your plants enjoy the best possible environment.
This choice mirrors the logic behind double-pane windows: it’s all about optimizing insulation. The result? A greenhouse that stays cooler in the sweltering summer heat and retains warmth during the chilly winter months.
This high-impact, UV-stable glazing not only shields your plants from damaging UV rays but also maintains a consistent temperature year-round for optimal growth.
Enhanced Security: New door and window locks have been introduced to offer increased protection against stronger winds, ensuring your greenhouse remains secure in various weather conditions.
Fast Shipping & Warranty: No need to wait for weeks. Enjoy fast and smooth delivery via FedEx Ground (ships within 3-5 days)! Backed by a 10-year warranty on the frame and polycarbonate glazing, you can have peace of mind with one of the strongest warranties in the industry.
Additional features:
Above-Average Interior Height: The 7.5′ peak height greatly helps in displacing heat, while also allowing tall gardeners to stand straight up inside their greenhouse.
Innovative Assembly: Featuring a patent-pending Twist & Lock construction alongside a rigid “ribbed” design, assembling your greenhouse is faster and easier than ever, requiring minimal tools and effort.
Optimal Ventilation: Featuring 2′ x 2′ roof vents with automatic openers, the MONT Greenhouse ensures great air circulation without the need for electricity, keeping your plants healthy and thriving.
Accessibility: A large double door (4′ wide x 6′ high) provides easy access for garden equipment, making planting and maintenance tasks more convenient. The door is hinged and lockable, offering added security.
Efficient Water Management: An integrated dual gutter system simplifies rainwater collection, allowing for efficient water management and sustainability in your gardening practices.
The Riverstone MONT Greenhouse is a gateway to a more fruitful and enjoyable gardening journey. Whether you’re a seasoned gardener or just starting out, this greenhouse offers the quality, functionality, and flexibility you need to succeed. Elevate your gardening today with the MONT Greenhouse and turn your green thumb dreams into reality.

FAQs
Is the frame anodized?
Yes & No. The aluminum frame is anodized. However, the black frame is electrostatically painted.
Is the black paint powdercoated?
No, the black paint is electrostatically applied which is stronger than powder coating. It is very difficult to scratch and should not fade dramatically. Riverstone Industries guarantees it for 10 years.
Is the aluminum frame cooler than the black frame?
Yes, the aluminum frame is on average about 7 degrees cooler than the black.
Can the MONT be attached to a concrete pad? If so what are the dimensions needed for the concrete pad?
Yes, you can use a concrete pad. Riverstone Industries recommends that you add 3 – 4 inchs to the pad on all sides. For Example: The 8ft x 8ft (exact size of 8.1ft x 8.1ft) would need a concrete pad of 8.4ft x 8.4ft. Note: Riverstone Industries does not provide concrete screws, you will need to buy these from your local hardware store.
What tools do I need for the assembly or is everything included?
Not everything is included. Here is a list of tools you will need and items included:
Work gloves
Safety goggles
Spirit level
Tape measure
Step ladder
Clear silicone caulk tube
23 1/8 inch spacer (included)
7/16 wrench (included)
Philips screwdriver (included)
Flat screwdriver (included)
5-foot bungee cord (included)
Can I extend the MONT Greenhouse later?
Yes, it is expandable in 4ft increments.
We live in a seismically active area south of San Francisco. I’d like to install the greenhouse on a hill. Is this the best greenhouse for my conditions?
MONTs are very sturdy greenhouses. However, the greenhouses are not tested for earthquakes. What we can suggest for you to do is to check the bolts and make sure everything is tightened after an earthquake or from time to time. The panels won’t pop out unless the frame is loose. The channels are made to fit the Polycarbonate snugly.
What does the ventilation fan do versus the auto openers in the roof?
Automatic vent openers are self-contained units which require no electricity. It is a temperature-sensitive device that automatically opens and closes a roof vent. So, they release heat and they basically require wind to make the air flow through the greenhouse. The powered ventilation fan gives you more control. It removes excess heat by creating air movement throughout the greenhouse. However, it’s just a fan, not an AC unit. So, on very hot days, you’ll still experience higher temperatures inside your greenhouse.
Do the doors swing out or slide to the side? What is the door width?
It’s a hinged door so it swings. The door opening is 4ft x 6ft.
