better to move air indirectly than point it right at a plant -- unless it is a very weak fan. A fan or two pointed down the sides will create a cortex.. if you see little jiggle in leaves all over the place, nothing profound, that's enough.
circ fans can even RH out but it can't lower the overal average RH. need a dehum for that.
easy to kill pistils with wind burn... leaves may seem robust for a day or two longer, but will show wind burn symptoms too.
