I’m with you about not using a dome. I’ll use it until it sprouts but not after. Emilya said that she doesn’t recommend using and her advice has been working for me. CLI'm on the other fence on this and would never use a dome for starting seeds. I've had friends and other growers experience wilt off/damp off disease doing it like this. It's a common problem with high humidity and lack of airflow.
Domes are for rooting clones in cubes, not seedlings in my book. New sprouts do well and will survive over 40% RH. It's more important to focus on not watering to much and having good and light air circulation going over the pots.
That being said it might work and my friend still do this even though I tell him no to. He has maybe 50% success rate on his seeds. He says he doesn't need to water as often and well that might be true the problems still persists.
I've started hundreds of auto seeds many years ago at ambient humidity in northern Europe with more than 90% success rate. Maybe at 30-40% RH?
