Mycelium has a grain preference, it seems. (Brown rice, Popcorn mix)
I had a bit of grain left during my last run, so I mixed the bits I had left.
This is interesting, actually. Over the next few months, I'll continue this experiment to see what grain mixes might work better for spawn.
While this wasn't a "proper" test, I had still hypothesized that the higher starch content in the popcorn would do better. I guess not.
I'll try and separate testing into different categories like starch content, moisture content, mycelium strain, etc. There is probably a ton more conditions to isolate as well.

Interesting. What spawn was it ?
I have quite a bit of popcorn kicking about. Did you pressure cook it first ?
Mixed cubensis genetics.
Popcorn is great when used alone without rice. I pre-cook it to ~60-80% hydration'ish, or when I can bite into it easily and the center has just started getting hydrated and isn't crunchy. I'll fill my spawn jars and load it in my pressure canner for about 90mins or so, depending on how many jars I have.
There are methods on YouTube for no pressure canner popcorn, so you can get away with a quick pasteurize it seems. Popcorn is obviously food-grade, so it's going to be fairly clean out of the bag.
So far, popcorn is also working awesome for pink and golden oyster spawn. Once Shiitake and Lions Mane get started, which takes a bit anyway, they do fairly well. I do want to experiment with adding peptone to the water when I pre-cook it to see if I can give it a little more "kick".
Price is variable and is only really cost effective with +50lb bags, if that is a concern. That is just about pinching pennies.
That's class. So I'll need to boil them to give plenty hydration. I'll need to give this a shot. I'm looking at oysters if I can get an easy enough substrate
The goal is to hydrate them "just enough" but not so much that the kernels split. Honestly, about 20% of the kernels split in my last run and the mycelium loves the easy access to the starches.
I am doing a masters mix (50/50 hardwood saw dust, soy hulls) as well as some straight-up Aspen shavings as a test. Animal bedding is dirt cheap, so if my yield is similar to the masters mix, I'll save some more cash that way.
Also, I'll keep this community updated then. I have already purchased several types of substrates and additives to experiment with. Learning how to chase total yields when I was growing cannabis was fun, and it seems easy enough to continue doing that.
Next stop for the near future is spore collecting and strain isolation. I really want to start a business from this and develop some productive strains.
My understanding is that you want to boil them until they're soft enough that you can easily split the kernels with your nail. For the batch I made, that was about 20-25 minutes at a hard boil. Compared to the batch of rye berries I made the same day (boiled for half that time), I think it took about a week longer for the mycelium to really get going in the popcorn, but otherwise all jars are doing equally well.
One big difference, however, is for long-term storage. I prepped my jars about three months ago, and still have some sitting in the closet. The jar with rye berries now has about 3/8" of water standing in the bottom (and this only started happening about a month and a half ago), while the popcorn jars do not have any standing water and the mycelium still looks more like cotton candy.
So my take-away is that if you're in a hurry to expand your mycelium, rye berries will get you to the fruiting stage faster. If you plan to let your jars sit for awhile, popcorn is definitely the better option.
Ah yes. You bring up good points.
I just remembered that ease of a "break-and-shake" is a thing as well. Popcorn simply doesn't stick together as bad.
It's also the reason that I rinse the hell out of my brown rice. It'll keep the free starches from acting like glue.
Hmm I haven't tried rice, didn't even realize that was a thing, but yeah I can see the starch being a problem. Maybe over the Winter I'll have time to work more with mine, I've been crazy busy the past week getting a new server in place but it's finally up and running now.
Brown rice colonizes really fast but it's only really good if you plan to use it as soon as it's ready. Otherwise, it'll break down fairly quick and is a pain to spawn to bulk after it does.
I got hooked on this hobby after innoculating some Uncle Bens 90 Second rice bags and learning how easy it can be.
With the popcorn, I split one jar between two bags of straw and it worked well (but of course took some time to fill in). Since the rye berry jar has so much liquid on it, I might just dump the whole thing into a single bag when I'm ready to spawn the next one.
The next thing I need to figure out is spawning a colony from the existing mushrooms so I know how to keep the cycle going. And that'll require having some new grain jars prepped and ready to go. Maybe in a few weeks...
That's excellent. I'd just like to grow oysters so I don't need to spend money on things I can grow. But it's a weigh up of buying substrate vs just buying mushrooms.
Just playing around with things. Have tried some wood shavings and some wood from the wood shed. So similar kinda thing as you. You are just more robust. I kinda just chuck stuff at it and see if anything sticks.
My issue would be if my spouse are good enough in the first place
