Sorry for dropping off - work & life have been very busy lately.
My couple of PF cakes that I made have kept my head clear - microdosing every morning in a little tea.
I've been trying to bulk up. I've dumped lots of stuff because basically I didn't believe folks when they said that you don't want a sealed container for bulk (after pasteurization). But now I've got some buckets with filtered holes, and I think I'm losing pretty badly to cobweb mold still. When I mix my bulk with my rye grain spawn, I've got to say that the rye grain has a mushy texture to it that I wasn't expecting, and although the jars are solid white, the colonization seems a little suspect. After shaking jars, they sometimes appear a little oily. I know that's a telltale sign of wetspot. I'm very familiar with the smell of wetspot and have a sensitive nose, and don't pick up any wetspot currently.
I decided to switch to straight rye grass seed (with buffer) and see if I have any better luck. I inoculated 21 RGS quarts earlier in the week with an isolate (Treasure Coast), so it will be a little while before I can try at bulk again.
I think next time, I'll add an oscillating tower fan on the boxes. I opened the boxes this morning, and they were a little wetter than I would have liked. So hopefully with the fan, I can fix the wetness problem and the cobweb problem.
Feeling pretty discouraged. I'm not sure if there was something wrong with my grain, if there's something wrong with my straw, my WC, or my pasteurization technique. I started using an Instant Pot for pasteurization of about a gallon and a half at a time. It is so easy - I'm not certain it's working, but I don't think I could find the time to try another pasteurization technique.
In the past, I had lots of luck with coir + WC, so I'll probably try a little of that again. I was really hoping to get the straw working, but I suspect perhaps the cobweb is endemic to the straw. So we'll see if I can rule that out.
I'm going to try to be around a little more moving forward. The doses I am taking are helping me be a more effective person in general, so time is beginning to free up as I clear my backlog.
