Waiting for the seedlings

I started 56 pots, with 4 seedlings each on Saturday- 4 pots each of 2 different eggplants, 4 pots each of 5 different peppers, 4 pots cherry tomatoes, 6 pots each of purple and striped tomatoes, 4 pots of greek basil, 4 pots of purple basil, and 4 pots of Red Kuri Squash. It's a little early for the squash. Yes, the seedlings are sitting on a waterbed- it provides nice bottom heat, and no one is sleeping on that bed right now. I thought it was better to turn the bed back on for a while than to purchase a warming mat.
