This portable greenhouse covers a 71-in by 40-in stretch of garden under a 66-in tall PE canopy, giving herbs, seedlings, and container vegetables a sheltered spot from early spring through late fall. Wear-resistant PE-coated metal tubes tolerate summer heat without rusting, and the tear-proof cover keeps rain and cold drafts off tender leaves. A full-length zippered door swings open for daily watering, while the top window pulls warm air out before it builds up. Overlong cover edges take stones or soil, and four wind ropes with metal stakes hold the frame steady in a storm.
