So I am new and I just made my first LME kit. When I go to check on it I see no activity on the air lock. No bubbles at all. It's in a bucket so I can't see the action inside. Making me wish I had something see through. Later today it will have been 72 hours since I pitched the yeast. I can say it smells good. So maybe the bucket lid has a leak? Should I just wait and guess when it has been enough time? Should I get more yeast and try and repitch it?
