I turn the fans off about an hour after harvest. If you are still growing , you need the fan on.

They are only about 3 weeks old obviously im not harvesting for quite a while thanks 4 advice bro

So I guess that means your fan is gonna be on for quite a while then, eh? I mean, dadio161 answered your question by saying he doesn't turn the fans off until about an hour after harvest. That means the fans stay on all that time. It stays on until harvest...

As long as they're in their grow medium, they need that fan.

"Keep em dancing" - I thought I'd get away with no fan from week 1 to 2 but no! If you keep your ladies dancing they will grow up strong and healthy.

exactly.
Fans should run 24/7 .
This will create all the oxygen your plants will need . More fans , the better.
Fresh circulating air will help prevent mold .
Don't go crazy now and blow the ladies over. lol

helps control mold & strengthens the plant . . .

IMO you keep your fans on all the time, i have had my fan on for 2 months solid now without turning it offf! i have never read or heard of anyone having an on/off cycle for a fan, although i could be wrong IMO

No fan, no fresh air, no breathing plants...

(Or, at least, asthmatic plants)

My only fan that shuts down at lights out is a dedicated light cooling one.

I have one socket for my tent open and a fan running 24/7

i would like to add to the question. I'm growing in my closet and i have a fan turned away from the plants on low. I close the door when not tending to the plant and theres no real air flow coming in. i can not modify the closet at all should i just leave the door cracked?
