I am trying to grow live cultures, but keep failing...help!?

Question

First I heated the milk upto 185F and cooled it down to 115F and then mixed with plain yogurt in plastic jar. I closed the lid and left it outside for 5 hours and it became yogurt. Okay, my question starts here. I'm trying to make those live cultures into visible big size. How can I do that? I left my other jar outside for 2 days, but it still doesn't grow as big as I want. I want at least pinky nail size. Does anyone know how to do that? I really need those live cultures. please help!

Answer 1

if I'm on the right tram track --- I'm thinking fungi ( mushrooms ) or similar --- and indeed if that's the case , i can only suggest high humidity ( as opposed to high temperatures ) good luck
