One kit has everything needed to add downspouts to a Grandio Greenhouse.
	Automatic Roof Vent Opener - Automatically opens and closes the roof vent window based on temperature changes. The opener contains a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. When the temperature cools, the mineral contracts, and a spring closes the vent, resetting the piston. The vent opens and closes gradually, allowing the right amount of airflow for cooling.
	Auto Louver Window Opener - Automatically opens and closes the louver window as the temperature changes. The opener has a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. As the temperature cools, the mineral contracts, and a spring closes the vent and resets the piston. The vent opens and closes gradually, providing just the right amount of airflow for cooling. This Auto Louver Opener attaches to the left side of your louver window.

A backflow preventer ensures water safety by preventing siphoning into the main supply.
	Moisture Control Kit - featuring Anti Dust Tape and Waterproof All-Weather Silicone Caulk, protects your Grandio Greenhouse from insects, dirt, mold, and algae. The tape's 45-micron filters allow condensation to escape while preventing algae and mold growth with a fungicidal coating.
