Autoflower freezing temp?

Hey RIU,
I have a few autos out in a secure location. We had to nights of 30degreees. Instead of hiking a long way to check if they are dead. The plants are only 2wks old with their second true set of leaves out. I figured i might as well ask if anyone had experience with the autos ability to withstand freezing temps. I am judging whether to pop more beans or get my tea ready to take out for a watering...any help is appreciated. Strains out there...

At 30f/0c the plants should survive OK, but as a grower(&smoker?) you should really be spending more time on actual 'time management' meaning that the plants are cold and sad, and NOT growing , means you put them out too early,
Why struggle now, when waiting 2-4 weeks that they may flourish?
Try and keep them inside under a red hps or 2700k to get them to stretch, so you plant out plants at 8-12 inches tall into holes that are 7-11 inches deep, deep enough so the plants can survive

good luck

Yea I know when my plants go out for my latitude...Anyway they survived the late frost and I should expect some nugs in a couple months. I will upload a pic of my little setups tonight
