If possible, locate the greenhouse where it will receive at least 6 hours of direct sunlight during the winter months. A good site would also be sheltered from high winds, close to water and electricity, and easily accessible from your home and garden. Avoid a site that is boggy, soft landfill, near a children’s play area, or shaded by buildings or trees during the winter.

The best orientation is to position the greenhouse with length running east and west. This will provide more heat gain from the sun during the winter. If the southern exposure is restricted, but open to the east, southeast, southwest, or west, turn the greenhouse to the winter sun. Remember that the sun is much lower during winter.
