Microgreens and cold day 2

It's been raining all night and this morning it got cold enough for a brief hail, my seeds inside would go as usual, my outside seeds however, will experience a cold shock.
A cold shock wouldn't necessarily mean their demise, seeds are made to go through the seasons cycle and come up when the temperature is right. Some might even benefit from the cold shock as there's suggested to put some seeds in refrigerator before sowing. However, I'm concerned about the veggies I sowed last week. They might have already started to sprout and cold can kill them.
There's no pictures because not much happens in the first week or two.
