Earlier this week I planted out 28 seedlings that I started back in February and March, after hardening them off for a week. Now I am wondering if maybe I should have waited longer on the smaller ones. 
(I still have over 75 similarly small ones inside the house, but I think that maybe I need to let them get bigger before putting them out.)
That's a nice setup. In this climate, if they get plenty of sun, they could have been planted a month ago. The only "problem" is that by the time they bloom next year, they'll be packed pretty tightly. I have an old stainless-steel boning knife that I use in the garden, and it's very handy for cutting out the unwanted seedlings as they bloom. That way, you don't need to try to wedge a shovel in there, the knife lets you "cut & scoop" out the crown without disturbing much else.
Is that a "leaky pipe" watering system, or are there emitters?
What kind of soil mix is in the bed?
Did you have to line the bottom with wire mesh for gophers?
