The popular 12X20 GrowIT Greenhouse (Peak Style) from ShelterLogic, a leading manufacturer of vinyl shelters and structures, is a great all-season growing space for your plants. This greenhouse offers great functionality and size at a very affordable price point.
Popular with both hobby and small commercial gardeners alike, the greenhouse is ideal for starting seedlings, wintering plants, and just about any other need. It offers plenty of working area inside as the peak height is 8', making it easy to accommodate even the tallest plants.
The rugged all steel frame is designed for quick assembly in just a couple of hours or so with just ordinary household tools and all the required hardware is included. It has a Dupont™ thermoset powder-coat finish for added durability as it prevents rust and corrosion and won't chip or peel off.
The triple-layered polyethylene cover is UV protected and is a sharp translucent white hue. Anti-fungal and anti-aging agents have been added along with fade blockers to help ensure a long life.
Superb ventilation is another key benefit of the greenhouse as the front and back panels have vents for cross ventilation to help keep your plants at an optimal temperature. With its large area, rugged construction, and classic design, the 12X20 GrowIT Greenhouse is a great addition for gardeners of all levels.
