Has anyone ever heard of putting a fan on seedlings? I heard that doing so increases the diameter of the seedling's stem and keeps them from getting tall and lanky.
Any one else heard of that? Anyone tried it?

I have heard of using fans. It is supposed to produce a stronger plant and have less problems with damping off I think. I don't know much about it though. The only fan that I had on when my plants were growing last year was a ceiling fan.

I put a small fan on my seedlings as soon as they get 2 sets of true leaves. I set it on low and use the rotating option so it dosen't blow constantly in the same direction.
It seems to keep disease down more than anything else,but I suppose my plants are stronger when I go to harden them off.

I read that having a light breeze over tomato seedlings helps make them sturdier. This is suppose to lessen the stress on the plant during the hardening off period.

A small fan from seed start helps reduce damp-off.
