The founders of Riverstone Industries have brought their decades of greenhouse experience to the new Monticello 8X8 Black Greenhouse. It features classic gable styling and is a beautiful addition to any garden.
Every aspect of the Monticello has been designed for durability. The frame is made of the highest quality extruded aluminum and the roof has dual joists to withstand high snow loads. The greenhouse is electrostatically painted to ensure proper and even coverage, and it comes with an industry-leading 10 year warranty.
The panels are of the highest quality as well, as the Monticello includes 8mm twin-wall polycarbonate wall and roof panels that are both UV-stablilized and impact resistant. These provide much more insulation than the typical 4mm or single-wall panels found on other units, and are the same panels used in commercial-grade greenhouses.
The Monticello is designed to be assembled in just four hours or so depending on how much help you have with just common household tools. Features like quick-connect screws, the integrated base, the integrated gutter and downspout system, and the pre-hung hinged door and vent speed up the process.
The tall interior height of the greenhouse gives you plenty of working space for even the tallest plants. The Monticello 8X8 provides the durability of a commercial greenhouse with the practicality of a hobby unit, ensuring that it will provide your family enjoyment for years to come.

Drip Irrigation System - The Genesis Drip Irrigation System allows you to deliver the proper amount of water directly to the roots of your plants. Each system can be customized to fit your specific growing needs. The kit includes 48 drippers which are designed for container and planter gardening. The second part includes 4 misting sprinklers which increase the humidity inside your greenhouse. This drip irrigation system has been designed by fellow growers and is sufficient for greenhouses up to 24 ft. long as 48 ft. of hose is included. A pressure regulator and quick connect are also included to easily get the system up and running, and no tools are required. A garden hose (not included) and water source are required as well.
Electric Heating System - This Riverstone heater makes it easy to keep your plants healthy during the coldest times of the year. It includes an adjustable thermostat with two heat settings to help set the proper temperature inside your greenhouse and has automatic fan control and a built-in thermal cutoff for safety. The heater includes an adjustable ceiling mount bracket and adjustable louvers to direct heat to the desired area of your greenhouse. It generates between 2500-5000 watts (21 amps @ 240 volts) and the rugged heavy duty frame has a taupe (tan) color. The heater is 14" wide x 12.375" deep x 12.5" tall, weighs 27 lbs., is UL listed, and is perfect for greenhouses as well as shed or garage use.
Electric Ventilation System - This ventilation system includes a 16" motorized exhaust fan with built-in shutter and a separate thermostat. The aluminum fan blades and PVC shutters are designed for efficiency and longevity. The fan has a 1/10 HP direct drive motor at 120 volts that is completely enclosed and maintenance free and has a rating of 1250 CFM. The single pole thermostat is made in the USA and has a large dial that is accurate to 2 degrees. The fan mounts flush to the exterior wall and has a nominal size of 17" wide x 17" long x 6" deep.
Extra Roof Vent - Riverstone makes it easy to add extra ventilation to your greenhouse with the roof vent kit. The vent is made from the same high quality aluminum and polycarbonate and features a 10 year warranty. It is designed for quick installation in only about 30 minutes. The vent includes an automatic vent opener.
Flooring Kit - The flooring system for this greenhouse is made of customizable 3" breakoff square segments from 100% regenerated polypropylene (HDPE). The interlocking modules are perfect for creating a safe anti-slip surface to walk upon, even in high heel shoes, while allowing for drainage. You have your choice of six colors (green, gray, blue, black, brown, tan) and 69 floor tiles are included for this greenhouse.
Hydroponic Seeding Trays - The RSI hydroponic seeding trays make it easy to start hundreds of new seedlings at once. All you need is a pool of water in which to set the trays, and water will wick into the new seedlings as needed. The trays come in packs of two and are made of commercial-grade polystyrene. Each tray has either 128 or 242 pyramid shaped cells, virtually eliminating transplant shock as the design prevents roots from getting tangled or needing to be cut for removal. The rate of transplant can be as high as 90%, much higher than other styles of seeding trays. The seeding trays float and are reusable as they should last for years. Each seeding tray is 14" wide x 30" deep x 3.5" tall and made in the USA.
Internal Shade Cloth - The internal shade cloth kit for Monticello greenhouses is designed to easily install inside the greenhouse so that it doesn't interfere with roof vents or side windows like regular shade cloths do. The commercial-grade shade cloth is 63% translucent and comes with a 7 year warranty. The cloth comes in two 8 ft. by 4 ft. sections so that it works well with the automatic watering system. The cloth is easily opened by simply pulling it back and can be closed by pulling it tight to the opposite end. The kit includes grommets, commercial filament, and bungee balls for tying the shade cloth.
Louver Window - The 18" square louver window provides additional ventilation for your greenhouse. It features a solar-powered opener as a piston with a wax-filled cylinder expands and contracts as the temperature changes to automatically open and close the vent. When closed, the louver slats overlap each other to prevent insects from entering. It is made from non-rusting extruded aluminum and is made in the USA.
Overhead Automatic Watering System - The 8 ft. long watering system is a commercial-grade system similar to that used by professional growers. It is designed to hang from the ceiling and includes one weighted sprinkler head. The digital timer allows you to automatically schedule your watering cycles to suit your climate and time of year. The hose is also a commercial product and is specifically designed to prevent mold and bacteria growth, ensuring years of safe use. Installation is easy as one end of the system is attached to the timer, and other end of the timer is attached to the spigot. The watering system features a 5 year warranty.
Plant Caddie - The plant caddie is a clever pulley system for your hanging plants. It allows you to raise and lower hanging plants for easy access and watering using a simple pulley system with a patented manual pull brake. This saves you from having to climb onto a chair or ladder. The strong reinforced brake cord extends up to 42 inches to reach even high areas. Each plant caddie holds up to 22 lbs. and is designed for both inside and outside use. The ratcheting system is the perfect way to easily adjust the height of your plants. Made from plastic, steel, and aluminum, the plant caddie features a lifetime warranty.
Potting Sink - The 33" wide x 20" deep x 7" tall large outdoor potting sink is unique to Riverstone. It includes a mounting kit so that it can be easily attached to the inside or outside frame of your greenhouse. The built-in detachable hose reel can hold up to 200 feet of garden hose, which is not included. The sink is extremely convenient and is perfect for your cleaning or watering needs as it can be used for washing vegetables, cleaning tools, or even simply rinsing your hands after working outdoors.
Solar Ventilation Kit - The solar ventilation kit allows you to circulate air through your greenhouse and help keep your plants at a comfortable temperature using only the power of the sun. The kit includes a 40 amp solar panel with brackets, a 16" commercial exhaust fan, an aluminum 5 louvered fan cover, and a thermostat. No electrical outlets are required at all and so this kit is perfect for locations where electrical connections are unfeasible and an off-the-grid setup is required. The panel is twice as powerful than what is needed to operate the fan, allowing for optional lighting and heating attachments in the future. An optional marine battery can be attached as well to provide power on demand. Everything is designed for easy installation. The kit includes a 3 year warranty and is manufactured in the United States.
Vegi-Bee Mechanical Pollinator (Battery Operated) - The 7.25" wide x 2.75" deep x 10.25" tall battery-powered Vegi-Bee allows you to pollinate your plants by hand easily for increased output. The pollinator mimics the high frequency vibrations made by the wings of bees during natural pollination, eliminating the need for for bees or the wind to pollinate plants in your greenhouse. The Vegi-Bee is perfect for all sorts of plants, including tomatoes, peppers, peas, and strawberries, and can increase harvest yields by 30%. The device operates at 38000 sonic vibrations per minute and includes a comfortable vibration reducing handle. A base unit and 1 AA battery is included, and the Vegi-Bee is water-resistant and FDA certified and only weighs 12.4 ounces.
Vegi-Bee Mechanical Pollinator (Rechargeable) - The 7.25" wide x 2.75" deep x 10.25" tall battery-powered Vegi-Bee allows you to pollinate your plants by hand easily for increased output. The pollinator mimics the high frequency vibrations made by the wings of bees during natural pollination, eliminating the need for for bees or the wind to pollinate plants in your greenhouse. The Vegi-Bee is perfect for all sorts of plants, including tomatoes, peppers, peas, and strawberries, and can increase harvest yields by 30%. The device operates at 5 different speeds between 29000 and 44000 sonic vibrations per minute and includes a comfortable vibration reducing handle. A recharging base unit and Ni-MH rechargeable battery are included, as well as an AC adapter and USB connectors. The Vegi-Bee is water-resistant, UL certified, roHS compliant, and only weighs 13 ounces. Two vibrating wands are included as well (11 cm and 18 cm).
Work Bench System - The well-designed work station kit can be installed on either side of your Monticello greenhouse. It is 8 ft. long and 24 inches deep. Two work bench systems will give you the full complement of benches on both sides. They are designed for easy assembly in just 20 minutes or so and can be set at any height within the greenhouse up to 4 ft. off the ground. The shelves are made of commercial-grade PVC and are vented to allow water and air to circulate as well as sunlight. The design allows for maximum floor space without extra support legs and each bench can hold up to 600 lbs. of load. The benches are backed by a lengthy 10 year warranty. They are designed to have one bench on each side rather than two stacked upon each other as stacking them would leave virtually no work space for the top bench.
