The popular Mt. Hood 6X4 Greenhouse is a perennial best-seller from NationStores/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.
Each 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 vents and one base vent at the back wall. A convenient Dutch door entry provides additional ventilation control and access.
No 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.
Automatic Vent 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.
