Commercial nursery pots are numbered as 1200, 300, 600 etc. here. I use 600 which is about 2 gallons for potting two fans of a registered daylily. A friend of mine uses 300s to pot baby seedlings

I remove the seedlings from the trays at about 5 weeks old, they should have there third leaf and a few roots coming out the bottom of the tray. Looks like you are using large trays(36-48 hole, I use a 72 hole) so they could stay in a little longer.
I also like early sun rather than late, the sun seems to help the daylily open better and faster.
