I grow more than a thousand plants myself, and sell transplants, so I start about a gazillion plants, all started in the house under lights. Soil blocks with a good, compost-based blocking mix (I use Vermont Compost Fort Vee) keep each plant to a 2" square right up to plantout. But for germination, I use discarded K-cups. Up to 30 seeds in a K-cup germinate nicely, still in Fort Vee. When they begin to get true leaves, I separate them from the K-cup, gently smush them kitty corner into the 3/4" hole in the 2" block, and fill in with a 3/4" soil block. Keep them bottom watered, tend the light requirements, bottom water by dunking the trays, harden off when appropriate, and that's it. Any time (rarely) they start to look off in any way, a bit of fish hydrosolate (sp?) in the dunking water perks them right up.
