The RT™ Max Muscle offers growers the ultimate in strength and versatility. With straight sidewalls from 4' to 10' tall it is an excellent choice for natural ventilation. The RT™ Max Muscle is framed using 2" x 4" column posts, 2" x 3" rectangular bows and 1" x 2" rectangular cross trusses. Growers take advantage of the extra square footage gained by using the 30' or 35' clear span width. In addition growers love the choice of up to 10' sidewall height. The RT™ Max Muscle is widely used by wholesale, hydroponics and transplant growers. Additionally, the sides and/or ends can be equipped with polycarbonate to make an outstanding and attractive retail sales center.
