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
childrens 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.
