Tips for my grow box fan (i have pic)

so im making a grow box and i put a hole in the bottom for a fan and a hole at the top so i can circulate the air, but the problem is the the fan would be blowing on my plants. what do you guys recommend i should do, or the fan blowing on the plants not that big of a problem.

If u have the fan on the bottom u would want to put it on the top hole so u take air out and pull air in to the cab from the bottom
 
i would do that but there is no way that i can get the fan in the hole at the top, it is to small. are there any other suggestions like should i nail a piece of wood in between the fan and plants?
 
noooo, air blowing on plants have never been a bad thing with my experience... if its too much and the temps are still right set it on low
 
okay its just because i was looking it up online and some people said that it wasnt that bad but then others said things like it could cause hermies (what is that) or it could stress the plants and kill them, so i just want to make sure.

the thing about hermies, basically anything can cause them but if a plant goes herm a lot of growers are just looking for anything to blame it on.
