Should i Keep fan on during nighttime for plants?

Fans are very cheap but should i run them at night for flowering plants and veg?

I do now.. but just wondering what some others might think .

I"m thinking they like the fresh air when hanging out so.

Fan yes. itll make stronger stems and move more humidity away from the leaves. The more fans the better.

I have an 18 inch wall mount fan and an 16 inch wallmount fan blowing in the room at all times

My fans run 24/7
