If you’re an experienced grower and gardener, the ShelterLogic 12' x 20' GrowIT Greenhouse Walk-Thru Access Plant Shelter is the ideal solution for you. This easy walk-through access greenhouse delivers quality construction, easy assembly, and best-in-class value. Constructed from a 1-5/8” tubular heavy duty steel frame, the greenhouse provides protection and a natural light source to your plants, herbs, and flowers. The steel frame has a premium powder coat protective finish to help resist chipping, peeling, rust, and corrosion. ShelterLock steel stabilizers add strength and stability to your greenhouse frame for a more durable plant shelter. The ClearView triple-layer heat bonded ripstop fabric cover is 7. 5 oz thick, waterproof, and has been UV-treated inside and out. The specifically designed translucent cover transmits light for optimal plant growth. Roll-up side panels provide your plants with maximum airflow and temperature control. The included bungee cord fasteners hold the sides open while the hook and loop fasteners keep the sides down. With the Easy Slide Cross Rail tensioning system, the cover is locked down for a snug fit and squares up the frame, while Ratchet-Tite tensioning provides solid cover anchoring to the frame. The double-zippered front door and rear door allows walk-through access and can be rolled up and secured to your preferred height. The front door and back rear panel both have screened vents to keep air circulating. The greenhouse kit has everything you need to assemble and can be assembled in about 2 hours with 2 people. 30” auger anchors are included with your greenhouse kit for easy anchoring.
