OG after mashing came in at 1.035, much lower than expected so I changed efficiency to match OG. I am thinking I should have double or ground the wheat much more than my standard grind. I usually stir a couple times but forgot this time as well. I do circulate my wort while mashing and can heat the wort as needed so opening and stirring should not be a problem maintaining temp. To up the OG I boiled enough water with dry malt extract to up the gravity.
