Shade Cloth – the MONT 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.
Greenhouse Sink – Designed to be mounted on the inside or outside of the MONT Greenhouse, and with a large working surface, it makes cleaning your tools and harvests extremely easy!
