It's Snow White, my favorite tomato of all. I put them into the vermiculite on 3/5 , inside the house, but no bottom heat. I did use a little heat with the echinacea last year and a few got leggy and weird. I'm trying room temp first. I haven't grown tomatoes inside in years. In recent years I always wintersowed them with good results. But last year was so cold and wet, they didn't sprout until May, so this year they're inside again. This has been the worst winter we've had in years.
So far I'm pretty impressed by the technique of sprouting things in vermiculite.
