Greenhouse Design

General Greenhouse Design Considerations
In order to engineer a system for you, we need to know your specific performance specifications. Here are some questions to consider when designing your performance specification.

Greenhouse Cooling Design Considerations
Greenhouse cooling requirements vary greatly depending upon the crop grown and the climate at the greenhouse location. Here are some general design guidelines that will work in most situations.

Greenhouse Cooling
This article discusses some of the principles, equipment, and cooling strategies required for the active management of greenhouse air temperature and humidity when the incoming solar radiation levels exceed the heating needs of your crop.
