Fan placement

2:47 pm in Materials and Resources, questions, Seeking Advice by samenrahmen

I’m struggling a bit where to put my fan. Fans, actually, but even with two of them (one is a rotating one) it’s hard to figure out.

Will enough wind bounce back from the window to create a breeze for all 35 plants if I put them on one side, should I mount them on top and let them blow down, or will that disrupt growth on the top tier, or … ?

Any recommendations ?
