First time bucket build, have question about fans and timers. I know that my active COB led heatsink fan must be on while light is on but would be useless to have fan on while light is off. Question is should my intake and exhaust fans be on 24/7 or should they be on timer. Should I have active LED fan on timer with my LED power supply? I plan on growing photoperiod strains on 12/12 when vegged out to flower.
