21" W x 21" D Mini Pop-Up Greenhouse

The Zenport SH3240 Pop-Up Greenhouse provides convenient, temporary protection for outdoor plants during unpredictable spring and fall weather. Set it over plants for springtime frost protection or extend your tomato harvest in the fall. Made from heavy-duty clear polyethylene, and a spring steel frame for many years of use. Measuring 26 inches tall and 21 x 21-inch across the top, this pop-up greenhouse is easy to set up when needed and folds down to approximately 1.5 inches thick for compact storage when not in use.
