good luck
i leave mine on all the time also....i have to the lights are on at night and the temps are wonderful. But in the day time when the light is off the temp range anywhere from 76-100. i have a 265cfm dayton for exhaust and a 6" inductor fan but they are just giving me good airflow. because i am only dragging in more hot air from the attic on intake. But i am going to try to connect the inatke hose to T-elbow on the bathroom exhaust so it will bring in fresh air from outside and cool air from the bathroom

much love .............nasty
