Daily misting should not be required for any reason until after the seeds germinate. This assuming the potting mix was properly wet when the pots were filled. But cow and fiber pots are notoriously bad for wicking the water out of the soil and into the pot material. Unfortunately misting doesn't solve that problem, only direct watering of the soil does.

The humidity dome is removed as soon as germination begins of course but until then if excess moisture is collecting on it then things are too wet inside. So cut back on the watering and prop one end of the dome open a couple of times a day to allow moisture to escape and fresh air to circulate. If necessary, remove it completely and leave it off for a couple of hours a day - it isn't required anyway and excess moisture and wet soil can do more damage than good.

Once germination begins be sure to get that dome off and leave it off.

Hope this helps.

I know this is 4 years old, but I was googling and your information is spot on helping me with a similar moisture problem. Thank you for that! One question I have is do I remove the dome when the germination process begins (as in I can see the white of the root coming out of the seed) or once there is an actual green shoot? I’m sure there is a better place for me to ask this...??? But I’m thankful for anyone’s time. It’s so nice that experienced folks share their knowledge online.

mi_bos - Welcome to Garden Web! Remove the dome as soon as you see the first sprouts popping up from the potting mix and get the seedlings up close to the lights to prevent them from getting leggy.
