Ideal fan speed for seedlings?

[juliando]

Hey guys,

Does this look like enough air movement? Is it possible to over do it - maybe stunt them?

I have a separate vent fan with filter - this is just a small oscillating fan for plant strength.

It's best not to let them get too dry. A VPD below 1.0 is usually recommended. I don't point a fan at them at all, but I do keep the air moving in the tent.

I agree with the above post.
I don't let fans blow on my seedling at all, they are taking moisture from the air and the fans can get things to dry.
Later in veg and into flower I let them rustle the leaves gently but the important thing to do is keep the air moving.
