Commercial Grade Greenhouse wall mount Fan System

This is a professional greenhouse fan that is designed for wall mount, and comes with oscillation and wind speed settings. Only 4 months old and like new. This fan is perfect for Green house and grow room application.
Fans are critical for growing healthy plants indoors. Fans control humidity on leaves and stems, and also provide the needed wind resistance that plants need to form scar tissue and toughen up for transplanting. Plants grown without wind become spindly and weak and will not do well when transplanted. Plants can also become subject to viruses, bacteria and other moisture caused diseases.
This fan sold new for $120 and is in perfect condition.
