Fan timing

Should my inline blower fan for carbon filter and cooling my 1000w HID stay on all the time? I will also have an inline fan blowing cool air in too.

If odor is a issue run all the time otherwise cycle it with the lights.

Just make sure you have plent of fans on the plants to help make strong plants capable of supporting large budsets

I keep mine on 24/7...The ladies love fresh air!
