@ducks4you , I don't put the seeds planted under domes in the sunlight. They aren't under any light but stay either on top my refrigerator or in the cabinet just above. This keeps the container and its soil at about 70°f. The morning I see sprouts, they go out into the South Window and the dome is lifted or removed entirely. They may retreat back to the kitchen in the evening because their kitchen location is warmer than that room.
I say "dome" and "container" but these are usually cookie boxes from the bakery - holes punched in the bottom, the clear plastic lid over the top. There are also berry boxes from produce and a few pots in plastic bags, gathered and tied above.
Yes, the onion seed has been in open flats in the greenhouse since early February. There are some perennial herb seeds and the brassicas (cabbage, etc) out there from their sowing until now. They aren't covered with plastic. They germinate quickly in cool temperatures. All the older seedlings (tomatoes, etc.) have joined them the last few days. Greenhouse thermostat is set at 60° overnight and 64° thru the day. Of course, if the sun shines - it may be a good deal warmer. I am always hoping that the sun shines ... however, the hard work you mentioned begins for me with having to pay very close attention to the greenhouse temperatures during partly sunny, cold, windy spring days
! I think tomorrow may be like that. The plants won't be happy with cold air whipping thru 
and, if the greenhouse is closed up, they will cook !

Scenes from 2017. So, I watered it heavily and reseeded. I check on it every morning, then Saturday I pull the top off and find that it is cooking!!
