Have had my peppers and tomatoes in the electric propagator for a few weeks now.....just went to see where they are all up......and want to cry

We had a power cut last Friday for a few hours...seems hubby switched off the plug at the wall and then forgot to switch it back on! Four days with no heat and in a very cold conservatory...will my peppers still germinate or should I call it a day and start again?
I don't have the option to start more unless I chuck out what's in there already as propagator isn't big enough.
Thanks in advance for advice
