I'm looking at heat pads to put under my seed starting trays. I need
several (say 4 or 5) and they get quite pricey when you also include a
thermostatic control. Do you have any clever ways to provide controlled
heating to your starting seeds that uses other stuff and is less costly?

Mine just has a little control switch that reads low - medium - high.
Get the cheapest that you can. I put mine inside a garbage bag to
protect it from moisture before I lay the germination tray on it, under
the grow lights.

Some people have luck germinating on top of the refrigerator, or water
heater. I used to do it under my heated water bed, but it wasn't near as
effective as the combined hot pad/light combo.
