i just tried the homemade lacto technique. but the twist was that i took a black trash bag out of the box, all folded up, and wrapped it around the growler and set it on the window sill. this weekend has been pretty warm. i came home and there was a pellicle on top. my thought was, i used hot water with the grain and it sat on the sill in direct sunlight. so i suspect the temp was close the at least 120f during the day. there had to be some conversion since the lacto grew over the weekend.
any other thoughts
