These two words say it all! Just by examining the specifications associated with our SS Series, you will be in agreement that there is not a stronger greenhouse on the market today. Design of this structure model is geared toward powerful wind velocities and snow/ice accumulation. Lower profile means more efficient heating and lower fuel costs. Five-foot sidewalls provide room for plant benches. Drop curtains provide excellent cross ventilation, or would you rather enclose the sidewalls? Both options are available. Specifications upon request. 2 7/8" O.D. ground posts are on 6’ centers and the customer decides the length. Optional ventilation, heating, cooling, watering, and truss packages are available for custom design per customer specifications.
