HELP...I screwed up...should I be worried?

My grow shed is on 9am to 9pm light. Yesterday was sunny and warm so I opened the door 6". Got ever so slightly high last night and forgot to close it.
Temperature went down to 28F last night. Sun came up at 7am. I don't think the temp should be a problem but the extra 2 hours of light? Will that confuse the plants and add weeks to flowering? I'm going to change to 7am to 7pm lights so this doesn't happen again, much easier than not getting high.
Some veteran help needed and THANKS in advance.

lol be careful, you should be fine it may stunt for a few days and they will need time to recoop

it'll be fine as a one off!dont worry.

Thanks for the input, feel a little better now.

Ur Good It Wont Do Any Damage
