To all of you that are sad because you've waited 3/4/10/12/18/36/48 hours and have seen no bubbles, I'd like to just RE-post the following sticky regarding fermentation start times from the stickies of this section:
https://www.homebrewtalk.com/f39/fermentation-can-take-24-72-hrs-start-43635/
The post has magical properties. I was waiting for almost 2 days for a batch to start bubbling, and was about to post the usual "WTF I pitched and had a starter and did everything perfectly and all of my other batches were fermenting 15 minutes after I pitched and I think my yeast is bad and do I have a virus and I washed my carboy out with lye soap could that be it and I don't think this is working properly and can someone fix this for me" post... when I decided to instead RE-Read the sticky on fermentation.
I read the ENTIRE thread...
then I grabbed a beer... drank it... and walked downstairs.
I looked at my fermenter, and just as I glanced at it.. A BUBBLE!
Then? 2 MORE!
Please follow the ritual of reading the entire thread, and then having a beer, and lets see if the magical properties of the post do truly exist!
