Green Giant: best for: • Fall • Winter • Spring 3 Season Greenhouses work well in most climates from fall through spring. The original Green Giant greenhouse is insulated so it can be heated for over-wintering and used to start seeds early. They tend to get too hot for summertime use.
Green Giant Clear: best for: • Fall • Spring The Green Giant Clear with twin-wall roof panels and clear single-wall side panels is a two season greenhouse. Good for extending the growing season in fall and spring. Because the side walls are not insulated, it is not suited for a winter greenhouse.
