Hi all, new to the forum. I’ve read almost all the posts here that I can follow since I don’t know much about this yet.
I ordered the vision koji-kin powder, and decided my first endeavour would be to get myself a good supply of koji-kin so that I wouldn’t have to keep reordering it.
I decided on using an old mini-fridge as my incubator, and a dual 50w grow light setup as my heat source. The koji grew very slowly, at less than half the rate Taylor describes in his guide. It did stay white, but did not seem to penetrate as well as his guide describes. After the initial koji growth, I removed the moisture source as directed. The first batch dried up to the point of being crunchy, which was my suspect for it failing to continue the process. The second batch did not get crunchy, however also failed to continue the process where it should begin to turn yellow and then continue on to green. Only very isolated small clumps of rice appeared to somewhat continue the process, but after letting it go for a couple extra days seemed to turn into the wrong type of mold…
First batch discarded… second batch waiting at home… I may take pictures to see what you guys think.
I have two ideas about this… first being that the koji is light sensitive, and the growth could have been retarded by the exposure to the harmful light waves emitted by the bulbs… second being… maybe my koji-kin powder got hot in the mail and the heat damaged the spores somehow also hindering normal growth.
I understand this is a lot from a newcomer, but I would greatly appreciate any help you guys could give.
I also used some of this apparently sub-par koji in a moto… which looks more like oatmeal and does not seem to be liquifying like most of the pictures that I have seen online.
