Did my 4th AG brew yesterday, a landlord clone kit from MM. Followed the recipe as per instructions, but couldn't get the wort down to 18deg so pitched a 19deg at 5pm yesterday. Have checked this morning and there is no activity from blow off tube is that to soon to seen any activity in blow off tube etc. The yeast was NBS ale, was in a garage before I used it would the recent hot weather effected it even if it was dried. Any answers or theories would be much appreciated
