I know you know this, as you referenced the pads, but FYI for the interested: you can get electrically-heated seed mats that only burn 20-40 watts, and cover a standard size.

I use them for both seed starting, and as a gentle, no-hot-spot heat source in my 3D filament storage/desiccant container. Even leaving them on 24/7 will only add a dollar or two to your monthly electricity bill.
