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

Allows fresh air intake at the lower level of the greenhouse. Suggested quantity of 1 per 4′ of side wall.

  • Aluminum framed, awning hinged windows with fiberglass screens.
  • Typically 3′ wide x 2′ tall

Ridge Vents

These are used to extract hot air from the greenhouse, pulling fresh air in from the wall vents.  Suggested as continuous unites along ridge.

  • Aluminum framed, ridge vent windows.
  • Typically 3′ wide by 2′ tall
  • Motorized drive shaft with scissor arm operators; 115v activated by control system.

Must be used in conjunction with side wall vents.  Traditional rack and pinion operators are not recommended due to their appearance, space consumption and safety concerns.  Each vent motor will require a control box separate from the control system.

Exhaust Fans
Exhaust Fan

Aluminum Exhaust fans made especially for greenhouses with aluminum slant-wall housing, louvers and safety grill. These extract the hot air, pulling fresh air in from intake shutters. Usually you’ll only need one unless in an extreme Southern climate.

  • Used in conjunction with intake shutters on opposing walls

Air intake shutters

  • 115v motorized, activated by the control system

Environmental Control System
Environmental Controls

A central controller for most cooling and heating equipment including wall and ridge vents, exhaust fans, intake shutters, HAF fans and heater.  This is the greenhouse specific, “entry level,” four stage control system with corrosion resistant cabinet, blueprents and temperature sensor.  You’ll need one per greenhouse (per zone).

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
