This is a list of suggested equipment for a level 1 greenhouse.  The equipment package is functional but simple, designed for elementary and middle schools that will be introducing young students to the horticultural and agricultural industries. You may find that some of the items in the level 1 package are not necessary based on your greenhouse design.  This package comes with all the features and benefits of an architectural grade greenhouse.

Side Wall Vents
Side Wall Vents

Equipment by Other Trades to Consider

Water Supply: Multiple water spigots with watering and misting hoses.
Floor Drains: At least one per greenhouse will ease clean up considerably.
Grow Lights: Since these are installed by a licensed electrician, they are the best resource to obtain the grow lights. Our recommendation is the high pressure sodium fixtures by P.L. Light Systems
