Howdy bigjon,

I feel that the fan or fans,should be always on when the lights are on,and when the lights are off,they should be off,so that the plants can rest and repair the the swaying because of the fan. It's kind of like the human body,it needs rest after exercise..when humans work out or exercise,they cause small tears in the muscle tissue,which needs to be repaired at night. By gittin the proper rest,it causes a strengthening of the main stem and branches,without undue stress. I'm not sure if putting the fan on a timer is good ,when the fan is off,heat can pool and build up,and the respiration rate of your plants goes way down..they need to be able to respirate well,when the lights are on.

Have a good one...Torog
