Made in the USAThe popular Mt. Hood 6X8 Greenhouse is a perennial best-seller from Sunshine GardenHouse. At six feet wide and over eight feet tall, it's spacious enough to comfortably walk and work in, yet compact enough to fit in any sized yard depending on which model you choose.

Shipping included for the contiguous United StatesEach Mt. Hood model is made with a clear natural redwood frame, twin wall polycarbonate and includes two vents with automatic vent openers, one roof ridge vent and one base vent at the back wall. A convenient Dutch door entry provides additional ventilation control and access.

Shipping included for the contiguous United StatesNo foundation is necessary as every greenhouse includes a Trex base that can be put onto any surface including soil. The frame base of the GardenHouse is a durable plastic with the authentic look, color and texture of redwood, but with the consistent properties of plastic, making it resistant to insect and moisture damage. It is only necessary to prepare a flat surface of gravel, wood, cement, or other material as indicated.

With up to four optional benches, you can optimize your space. With our re-assembled panels, you can easily assemble your Mt. Hood series GardenHouse in less than a day. Each GardenHouse includes easy-to-follow printed instructions, clearly labeled panels, and an excellent assembly video.

Included Feature

sunshine gardenhouse automatic roof vent openerAutomatic Openers for Roof/Base Vents - Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator's springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

Optional Accessories

4' Extension Kit - The 6X8 Mt. Hood can be made into an 6X12 structure with the optional extension kit.

sunshine gardenhouse anchor kitAnchor Kit - The anchor kit is recommended to protect your greenhouse against high winds and inclimate weather. Each kit contains two anchors, which are easily hammered into the ground. Two anchors are preferred each side. The anchors consist of 4 1/2" diameter x 16" rebar ribbed steel stakes, along with two cold galvanized anchor base plates.

Bench Kit - The elegant redwood benches are specially designed by Sunshine Gardenhouse to give you plenty of sturdy space to work on and display your plants. The 21" wide by 8' long benches run the length of the greenhouse, and each unit can hold up to four.  Made with clear natural redwood, these benches have a 5 year warranty. The benches can be stacked to provide even more growing area.

Extra Door - An extra single Dutch door can be added to back of the greenhouse to provide access from both ends and complete cross ventilation for your greenhouse. The extra door is available at no additional cost, and it replaces the standard back wall panel which has a vent.
