Ventilation switched on when???

Hi i just bought a ventilation system recently and i just finished setting up...
my question is when is the best time for me to keep it turned on? its plugged through a filter and a cooltube, first the filter then the cooltube and the ventilation at the end to cool down the bulb.
do i keep on all the time or just during the light hours? or switch it on many times a day?

anyone out there ?

check your humidity and temps during lights out to determine what on off schedule will work best for your situation.no pat answer works

ok thanks

if you don't intend running 24/7 its going to smell, if that's no concern then i'd go with what your light schedule is or the cool tube will be redundant!

i would run it all the time to keep good air flow going and to keep smell down

yes i thought i had to do that just wasn't sure... today i bought a speed controller for the ventilation it slows down the electricity running to the ventilation so i can have it on slow during night time and it wont wake the whole house up... makes lesser noise.
but thanks for your help
