This is the mini greenhouse that boosts tomato yields by allowing plants to grow without damaging restraints. The tubular steel frame has adjustable bars that can be raised and spaced to support a tomato plant’s foliage and fruit as it grows without harming stems or stunting its growth as traditional ties do. The included cloth-reinforced plastic cover protects plants from frost, wind, and pests to help extend the growing season. A zippered flap and vents at each end allow optimal airflow to maintain an ideal growing climate. Assembly required. 39 3/4" H x 63 3/4" W x 19 3/4" D. (4 1/4 lbs.)
