Tempeture drop!

I'm two days into the germinating process and my gas got shut off . This is my first grow so I'm trying not to screw up as best as I can. The temperature will drop to 60 at best and 40 at worst. What can I do to prevent them from dying or will they be okay just for tonight? the gas should be fixed tomorrow.

read your post wrong ,, thought you said plants
when germinating keep them warm as possible ,
but one cold night wont hurt

They could be slightly stressed overnight depending on the temp you keep the plants at during the day. In any case, they will be fine for one night.

Okay thanks. I was a bit worried even though it probably wasn't justified.
