>> practical, and probably effective.
Thank you, those are NOT my usual strengths!
I just couldn't think of anything elaborate and impractical this time!
Even once they are out of the 100% humidity, you might water them a few times with dilute4 hydrogen peroxide. That mold or fungus can't be very harmfull to the seedligns, or they would have fallen over already. But it couldn't hurt to chase it away faster.
P.S. If you have a little fan you could run briefly a few times per day,. that will make the stems grow stronger as well as reducing the humidity. I keep thinking about bringing home a small computer fan and wiring it up to provide a tiny breeze.
