This greenhouse assembles anywhere, without tools, in as little as 30 minutes. Similar to setting up a tent, the greenhouse is supported by 10 flexible rods that attach to the waterproof PVC canopy. The unit anchors to the lawn with stakes and tie downs, enabling it to withstand winds up to 60 mph, or it can be set up on a deck or patio. The greenhouse shelters plants from wind, pests, and driving rain, allowing you to extend the growing season into the fall and start seedlings early in the spring when outdoor conditions are not yet optimal. The clear PVC cover keeps plants visible and provides 360° of sunlight. Nine screened windows and a door provide air circulation, or they can be zippered shut to increase the internal temperature and humidity--ideal conditions for facilitating and extending the bloom of annual, perennial, and tropical plants. At 10' high by 9' wide, the greenhouse provides ample space for tables, shelves, or chairs (not included), and it comes with hooks for hanging plant baskets from the ceiling. The entire unit fits in the included bag for convenient storage. 120" H x 108" W. (49 lbs.)
