(Many square 3" pots in big transulcent tubs, but the snap-on lid was opaque.)
("Whatever" commercial seed-starting mix lightened with grit and screened pine bark fines.)
I have so much rain that at first I kept it all out by leaving the lid on ... but a solid lid lets no light in and slows ventilation. I was also afraid of slugs once weather warmed up.
But I figured they needed light & air, so I cut out the center of the snap-on lid and used translucent plastic film with just a few slits. Many small drainage holes in the big tubs, 4 large holes in each 3" pot.
I needed just a few survivors of each variety, but wanted dozens of varieties. Thus I put a different variety in each 3" pot.
