Whole Oats Prep Report

Hello folks. Thought I would share my experiences using whole oats for spawn. I picked up a 50 pound bag of triple-cleaned race horse oats from a farm supply store for $11.

I used three different methods of preparation, all of which produced the same results. They are as follows...
1. Soak/simmer 2. No soak 3. Inocuole's Impossibly Simple Whole Oats Grain Prep

All three methods were easy to execute. Inocuole's tek is pretty great. The only thing I had trouble with is getting the oats hot enough to steam dry. The batch I prepared was large, so my guess is that I did not use enough boiling water per the amount of grain. I love how the oats were FULLY hydrated after only a 9 hour soak
Oats are easy to prep and very forgiving. I was amazed that boiling the oats starting from cold water (no soak method) yielded no burst kernels and were perfectly hydrated. I made sure the grain was super dry and added a pinch of gypsum to each jar before PC'ing. The only thing I don't like about oats is they tend to turn out a little sticky, no matter the preparation. A shake took care of most of the minor clumping. There are a number of oats without the hull which seems to be the reason for this.

All batches were PC'ed for two hours @ 15psi. Here are some pics of the jars colonizing. They were inoculated with agar wedges.

Fully colonized.

All the jars fully colonized, but clearly have some bacterial issues. I went ahead and spawned the jars to bulk substrate (pasteurized CVG with worm castings). Of the five trays I made, only one produced fruits. The other four contaminated at 100% colonization with green mold and wet bubble. The tray that pulled through, I used I higher spawn to bulk ratio. Ended up yielding 5 ounces dry from that tray!

I decided to give the oats a second chance, so I prepared another batch of 14 jars. This time the grains were PC'ed twice. The first time for two hours @ 15 psi. Waited four days, then PC'ed again for another two hours. Then I inoculated with agar wedges. The jars fully colonized as of a couple of days ago. They ended being just as bacterial as the first batch. WTF! Went ahead and spawned them to bulk anyways using a high ratio of spawn to bulk. We'll see what happens. I'll be happy if I can get at least of those suckers to fruit like last time.
Conclusion:
Whole oats are easy to prep. Avoid the Nutrena brand that I purchased. Dirty AF, clearly better suited for feeding horses than growing mushrooms. I encourage all of you oats users to share your successes and failures using oats. Does anybody have a brand of oats that you have had consistent, reliable results with? Thanks for reading. Hope somebody finds this report helpful with your future grows.

I had a good bag of oats once they are all gone . I also just ran out of a bad bag of those producers pride brand oats       I used them all and can't wait to be done with them. Wedges didn't work fast enough, but LI's ripped through fast enough to have far less bacterial contamination. The pans didn't care for the oats, the gt's didn't mind...
So I made a pan li with 3 fully colonized blue corn p plates. They kind of won the race, but not really.
I think I'm going to take a break from oats and get some classic rye grain since I got the tamps happening on agar.
A good bag of oats is the easiest grain I've prepped, but until someone posts a link to some form of oats that they did not get a bacterial infection from.....I'm done with oats.

Did you ever figure out where your perceived infection rates came from? I'm using oats... prepped with Bodhi's TEKS. No infections for a very long time (transfer after transfer with no problems in a SAB).
Where did you introduce infection... at that high of a rate... ? The only place I can think it would have occurred would have been during your agar transfers...
Either that or it's a brand issue BUT I highly doubt that just based on the science of pressure cooking.
Holler at me if you figure it out.
Thanks.
