First off thanks to everyone who responded to my posts/questions regarding foam stoppers and OG of a starter. Yesterday, I brewed a "Double IPA"-Extract/Specialty grain recipe. I miscalculated water additions and ended up with 5.5 to 6 gallons of wort-OG was 1.074. I racked into the fermentation bucket allowing quite a bit of splashing (racked at 65 degrees). I then used an O2 canister and stone-three times for about 10 to 15 seconds each-swirling the stone around the bottom via the stainless steel tube. I then pitched my 1500ml of starter and another fully puffed out pack of Wyeast 1056. FYI-the starter was created the day prior using a way too high OG starter of 1.065 and a stir plate. It is now the 16 hours later-early I know but no activity in the Airlock. The lid is sealed tight, the inside part of the airlock is pushed up. Should I have any concerns? Thanks-
