after pitching yeast how long should you leave cover off. I usually cover right after I pitch and have never had a problem. but I've heard to let it aerate also.
I have checked my seals and my airlock they seem to be fine. I added honey to the primary to raise the gravity prior to pitching yeast. I did not rehydrate the yeast. I am brewing a I.P.A ptiched yeast at 72 degrees. Any ideas?
