Mini greenhouses can be tall or short, but generally take up less than about 10 square feet (1 sq. m.) of ground or floor space. Many gardeners use them in place of cold frames to start seedlings earlier than normal for their area, or indoors to propagate plants that need high humidity.

3. Can you use a mini greenhouse in the winter?

An unheated greenhouse can be used to grow greens during winter, start warm season annuals, propagate landscape perennials, and shelter frost-tender plants through the winter chill.
