fan flow direction?

[Louder Than Hell]

Hello, i deployed a couple of 3" pc fan @5v in my 20 gal horripilarium but now i can see all spikes rocking because of the the air flow.
The RO is bout 80% but i'm still afraid they may dislike it.
Should i try to direct the air flow somewhere else? Maybe it's more usefull at ground level on pots?

Also should i just leave one fan instead of two? Do they need a proper flow or it's just about dont leave the air totally still?



PS: what RO should I aim to?

I use three fans. Two are running inside tank 24/7 and blow right on the plants. The third comes on (through-wall) to dry out the humidity and moisture. It runs at night only for 4 hours. I think it is important to have enough air movement to make the leaves and spikes blow around. I can't think of any genera that do not appreciate air movement in a high humidity. My tank runs above 90% most of the time (except when the through-wall fan is running.) Hope this helps. Here's a picture of mine when I only was running one fan inside 24/7:

ro=reverse osmosis
rh=relative humidity
