I’m on day 5 of early veg with my purple kush auto?
Anybody?
Depends on what the objective is with your mini fan.
If you just want to improve air flow, you can turn it on whenever.
Mine is controlled through SmartThings, turns on when certain temps are hit and turns off when temp comes back down.

Just don’t recommend in germination or first week of early veg. Plants are very fragile during this time.
I usually wait until late veg unless there is a moisture issue.

Yes these aren’t industrial fans. Out of all of them that I tried this provided the most air flow.
But thanks to Amazon you can try others if you’d like and just return the losers 
They work for me to move air flow. If your room is too hot in general these fans will not cool the room down.
This is all advanced stuff here. Way above a beginner stage maybe your first grow you just let the machine so it’s work? You might be satisfied!
