I run a big 16" fan in my room from day 1. Obviously, not blasting on them, but enough to move some air.When would you introduce a light breeze?
I'd think you should be fine as long as it's not pointed directly at them on full blast. LoL
Lowest setting, and positioned to move air "passively", I'd say you're good to go now.
You're gonna have lids off/on over the next few days anyhow....
