A portable plant conservatory to fit your budget. These dome-shaped greenhouses are roomy enough for large and climbing plants. Great for season extending or overwintering tender cultivars. The patented design allows the unique curved surface to always align at 90° to the sun's rays for optimum light penetration regardless of the time of day. The UV stabilized PVC cover features a rugged, zippered door and adjustable top vents for air circulation. Our easiest greenhouses to set-up and take down, the durable fiberglass rods are pre-set into the cover and make assembling the structure a quick, one-person task. Comes complete with a sturdy storage bag.
