So on my 2nd batch I was in a hurry because we had to leave for church, I pitched the yeast without topping it up to 5 gallons. I realiz d this about 4 hours after and put a little over 2 gallons of clean water in at this point. It was dry yeast so I know fermentation shouldn't start until 12 hours after. Do you guys think I will be good getting the batch up to 5 gallons 4 hours after pitching?
