Power off and unattended for 18 hours in Veg! Help!

I went away for Christmas and was gone for around 18 hours in that time-frame the breaker for the grow room flipped off. I have some plants vegging they have been going for about a month from seed now and are about two feet tall. When I returned tonight I found the breaker was flipped. The room temperature dropped to 50 degrees with an outdoor temperature of 24 degrees and the lights were completely off. Where do I proceed from here? How can I tell if the plants have begun to flower? If so what should I do and is there a way to continue to veg? What would this effect? The plants seem to be in the same condition.

Thanks any help is much needed and appreciated. Let me know if you have any suggestions or questions.

Alright, is there a way to tell if it's flowering before buds become viable so that I can adjust my light schedule. Also what would have happened in late bud?

As long as it hasnt gone 12/12 yet, should be fine just get it back on time.

If it happened in flower time, you run the risk of hermies, or re-veg.

Simply reset the electric and keep going.
If it began making bloom hormones. Putting it back to veg times and continuing will allow the plant to "re-veg" and with the one/short time accidental change, the time to re-veg will be short and not to stressful.
You really don't have anything to worry about!

Check your timers if they weren't battery backed up and you were on schedules with pumps,18-6 etc..
Fyi,you can get emergency backup lights for 20bucks..they won't grow your plants,but will come on and 're-create a cloudy day'if your power goes out again..just a suggestion..
