I use seed trays ONLY outside (no plants in my house, no space). (we are in early fall, still a good 85-90 degrees high during the day, Saturday it got down to about 50 in the morning. Winter will stay similar, highs up to mid 80s but down to freezing at night)
I either have them going in the shade or on a table in full sun with a shade cloth that cuts about 50%. Depending on temps/wind/humidity levels I mist them once or twice a day. Luckily in the current circumstances I am not leaving the house and so I can keep a good eye on them....
With some seeds that take longer to germinate, I may throw a board on top of the tray for a time to trap the humidity inside (if they were in the shade, I would have covered them with plastic wrap, but this full-sun-shade-cloth-starter thing is a new thing for me and I'm testing).
