Selecting A Greenhouse
Location, Location, Location

Whether your greenhouse is attached or freestanding, it's important to choose a location (site) that will give you the most sunlight when it's in use, during fall and spring for most schools.

A greenhouse that's attached to a building above 40° north latitude should have an east/west orientation with the glazed area facing south to provide optimum winter sunlight. Greenhouses located below 40° north latitude can have a north/south orientation to take advantage of eastern or western exposures.

You should locate a freestanding greenhouse no closer than a distance of two and a half times the height of any wall or other object that might block sunlight. Also assess the role tree shade will play in your proposed site.

You'll also want to consider factors such as access to water, potting and planting areas, and ease of access for students. In any case, the site you choose should be well drained and not subject to settling of water or cold air.
