Selecting A Greenhouse
Greenhouse Styles (Freestanding vs. Attached)

In Texas, Crockett Intermediate School's science teacher, John Morgan, Jr., didn't factor in ongoing funds for heating and cooling the greenhouse. On a typical August afternoon, the temperature in the greenhouse soars to a blistering 103° F, taxing the vented roof beyond its regulating capacity. In hindsight, John wishes he had purchased one or two smaller greenhouses rather than the freestanding structure he did buy.

Greenhouses can be either freestanding or attached to a building and come in a variety of styles. Most commercial greenhouses are freestanding structures built in exposed areas with plenty of sunlight (maximum sunlight is the most important factor for efficient plant growth).

A freestanding greenhouse could be a permanent structure, complete with a foundation and automated controls, or a simpler (and much less expensive) hoop-type structure that helps you start growing garden plants earlier in the spring and extend the season for some vegetables into the fall. Freestanding greenhouses do have some drawbacks: In a school setting, they may be less accessible to classrooms and to sources of electricity and water, and heating costs tend to be higher. Attached greenhouses are generally more accessible, cost less to heat, and are closer to water and other services; however, they are typically more costly to construct and receive less total light than freestanding structures.
