Junmaidaiginjo tane-koji

We wanted to see what would happen if we tried to make this small portion of a very large batch of koji made from extremely polished rice (78% of the bran and outer layer removed) which is 1% more than the absolutely brilliant Dassai 23. Started to sporulate but don’t yet know what will happen since we are testing different humidity and temperatures. So if any koji makers out there are reading what temperature would you try to sporulate at? Have you ever tried with extremely polished rice?
