The Monticello Deluxe Kits include the greenhouse, and corresponding Work Bench, Watering System and Shade Cloth. You can find and purchase all our Monticello Accessories here!
- Work Bench System – the work station is a high-impact PVC vented platform with heavy-duty support bars that hold up to 600 lbs. The work station is designed for either side of the greenhouse and is very easy to install.
- Shade Cloth – the Monticello shade cloth is a simple and thoughtful design to keep your greenhouse cool by reflecting heat and sunlight. Each shade cloth is made from heavy-duty, commercial-grade polyester weave that lets in 37 % light and includes bungee balls for tying.
- Automatic Watering System – this system is designed to be hung from the ceiling of the greenhouse with 2 weighted sprinkler heads separated by 4’ spray in a circular pattern. The commercial-grade digital timer is designed to allow custom watering cycles depending on plant needs. The hose is designed to prevent mold and bacterial growth and the system is compatible with the shade cloth.
- Additional Roof Vent – The automatic roof vent is designed for simple and easy installation. It is made from the same high-quality aluminum and polycarbonate as the entire unit and includes the same professional-grade automatic vent opener as is included with the standard greenhouse.
