What other spawn substrates have you tried?

Though i'd start a post about any experimental spawn substrates people are using or have tried.
It does not matter if ultimatly it failed, a failure is still good info.
----
For those who havent yet tried it, I'm going to test Carrot slices, link includes water content.
- I can leave them out uncooked without contamination for quite some time.
- They stay whole cooked and also hold water for a very long time.
Lets see if it works. They might turn mushy, or just fail. Round 2 would be to use liquid carrots and paper.

I read there is a delicacy in China I think where they grow oysters on shrimp shells.

Weird and interesting. I wonder what micro nutrients it eats.

Here is the carrots test, 12 hours later, using paper spawn samples.

Re-grown and starting to eat the carrots.

Lot of sugar in carrots. I might be worried about the culture getting lazy or shocked.

Yup. I like to read about aliens and mutalopes. I wish you success and prosperity. I will continue eating popcorn. Despite my lack of Internet presents, i look forward to your presence here because experimental substrates are the best.

You might be right, mostly growing on the paper atm.

After I will try carrots as a liquid fertilizer.

A tip to see how something will do on a certain media is to make agar with it. I did carrot agar a few times but found it did better when diluted and a bit of starch added to the mix. Some food for thought.

I messed with pumpkins for Halloween which seem somewhat similar. The seeds colonized and worked as spawn. The pulp/strands I used to supplement a few blocks, they contaminated.

I've been playing around with Alfalfa a lot due to it's very high nutrition. 15-18% protein and a strong matrix from straw-like stalks for transport.
Seems a good combo for gourmet, medicinal and woodlovers. Can get a cube bag for very cheap and it expands to a crazy volume

Thanks Snazz for your alfalfa info..
Do you find that your substrate gets too hot if you over do your alfalfa supplement percentage?

I don't think it has much 'free nitrogen' it's mostly bound in animo acids.
It can start turning to silage if I go too rich. Although that's yeast or something.. Sterilization should buy lots of time. Limewater pasteurization works pretty slick as well

It would seem to me that the size of the carrot pieces could also be a factor. They seem much too big for the mycelium to easily colonize.
Also, were the carrots organic? If not there could be a residual fungicidal compound still contained on/within the carrot.

The size should'nt be an issue. But good point with the organic. #WTF@Myself, no they are not. Carrots mk2 inc.

I have been experimenting with paper and Miracle-Gro® soluble plant food. First I made a small sample, and placed a WBS lump into the middle.
----
After 3 days it looked like this:

10 days later it was used:

After 4.5 days:

----
Now i'm looking for organic methods.
Suggestions?

From what I've read, and my personal experiences seem to back this up, substrate "particle" (not sure if there's a better word for this) size is always a factor in speed of colonization and health of the mycelium. Smaller particles are faster to colonize but provide less nutrition for the amount of effort taken to colonize, larger particles provide more nutrition but take a lot of effort. A mix of sizes is often recommended; that's why you'll sometimes see recommendations made for a fruiting substrate that is 10-30% woodchips, to 70-90% sawdust.
I would personally try food processing the carrots so that you get a mixture of smaller and larger chunks.
Keep us posted! I might try a similar experiment when I PC rye grains next week.
On the subject of organic equivalents to the Miracle Gro plant food, I'm not really that familiar with the Miracle Gro product and couldn't easily find what its active ingredients are or what they're providing to the soil. That said, your easiest option would be go to a good garden store and ask them what they sell that's comparable to the Miracle Gro that's organic.
Something else that might work as a similar but organic method would be to make a compost tea with a molasses and a high quality MATURE manure. All you need beyond that is a large bucket and an aquarium air pump and you'll have plenty of lovely organic liquid fertilizer in no time!

Nice to know thanks for the info. Here is the label for the SPF.

Carrots seem to contain all the micro-nutrients I am after.
What I intend to do is liquidate the organic carrots. And replace the SPF and water.
Carrots are 80% water.

...oops, just saw you wanted spawn alternatives, whereas these where fruiting substrates.
