I just planted all my seedlings in cow and fiber pots. I only mist the plants daily, but am getting a lot of moisture running down the domes even though I have all four vents open in each. My room is 60-62 degrees but I also use heating mats under all. Can anyone give me info/advice on the excess moisture and how to control or correct it? Thanks.

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.
