Temperature swing during flowering

Hey all,

I just put my girls in to 12/12. With the lights on the temperature is around 78 to 80 degrees. With the lights off, it drops to around 55 degrees after a couple hours. This is because I continue to pump fresh air from outside my house in to my flower room at all times. Is this too large of a temp difference? I figure it should be ok, since the same is seen out in nature, but wanted to ask. I hope to hear from some of you. Thanks.

Your temp difference is OK.

55 is at the low end of OK for a couple of hours. Any lower and the plants will stop growing. 60 would be a better target low.
