The Sunshine Mt. Rainier 8 x 12 Foot Greenhouse Kit has everything you need to start growing your own organic produce and favorite flowers. With a beautiful clear, natural, and sturdy redwood frame and twin polycarbonate panels designed to protect your plants, this greenhouse looks fabulous as well. The large Dutch doors allows you to keep the door open without worrying about little critters getting in, and the doors and base are both made with recycled plastic. The four vents with automatic openers allows for plenty of air ventilation, helping to keep your plants healthy. A 12-foot staging area is included, which can double as a work station and gives you more room for growing plants. A shade cover is also included so you have greater control over the climate of your greenhouse, and it can also double as a wind screen in colder months. Measuring 12L x 8W x 10H feet, this greenhouse is large enough for all your growing needs. With preassembled panels, this greenhouse does not take long to assemble. Printed instructions as well as an assembly video are included.
