Can I purchase the Bench-Mart Greenhouse with only double-walled polyethylene, without the polycarbonate side panels? Also, does this greenhouse include benches on both sides and in the middle? To use double-walled polyethylene for the roof, a second layer of film and an inflation kit must be ordered separately. The side walls of the Bench-Mart Greenhouse come standard with polycarbonate panels for ventilation. This greenhouse model includes integrated benches on both sides and in the middle as standard features.
