Easiest "Microwave" Kinshi

Cross posting content from an international forum per request. This is a new method so I will say I cannot be accountable for anything bad that may happen from it.

 I use a recipe of 100g ~ 200g of wheat bran (you can substitute with soybean hulls) and 1000g of oak fuel pellets. I sterilize it in the oven at 250 fahrenheit for 20 minutes. I also add a small amount of calcium carbonate. Then I mix them together while they are still hot, and add boiling water until it is at "field capacity". I put them into 16 fl oz deli containers and there are three medium sized holes with micropore tape covering them.

Microwave in high for 20 minutes. In order for proper sterilization, make sure the holes covered in micropore tape are large enough and plentiful enough so that the container does not explode in the microwave. After these containers are cooled down to around room temperature, add the grain spawn with the mycellium into the container.

For methods that are not entirely sterile, it is better to be generous! I use homemade popcorn grain spawn. You should add these grains in a still air box or in the bathroom after a hot shower and spraying disinfectant into the air. Wear gloves, use alcohol on your hands, and wear masks!

 Soon you will see the mycellium spreading and see have nice kinshi! Expect some failures from contamination with this method. I prefer oyster mushrooms because they grow very fast and are one of the best mushrooms for unsterile methods.

The kinshi is completly colonized on the outside after about two weeks. I just have to wait about a week to make sure it is completely colonized inside as well, and to let the mycellium thicken up and digest the sawdust. None of the ~40 or so kinshi are contaminated whatsoever. I still suggest doing a pressure cooker method rather than the microwave method if possible.

Mushroom Type Notes:

Trametes versicolor (Turkey tail mushroom) is supposed to be the ideal mushroom for most beetles in the genus Lucanus (Lucanus elaphus, Lucanus capreolus, etc) I suspect Ganoderma lucidium is potentially good for these species as well.

Pleurotus sp. (Oyster mushroom) is good for most beetles in the genus Dorcus (Dorcus brevis and Dorcus parallelus). It is also the easiest and fastest to grow.

 
How many containers do you usually put in the microwave at once?

Also, did you get any mushrooms out of it? 😁

I try to not completely overcrowd it to make sure that the holes aren't covered. I usually put maybe 6 or so at a time. I don't let the mushrooms fruit, that would make the kinshi have less nitrogen and less nutrients overall.

Kind of out of topic but would fermenting the left over kinshi after harvesting some mushrooms make it a viable substrate? Or is it still less-nutrient rich compared to a normal flakesoil?

That is possibly a viable choice. When the kinshi rots without molding over, it turns into a very black substrate similar to very fermented flake soil. I imagine this substrate would have easily accessible cellulose and a decent amount of nitrogen from the bran or soybean hulls the mycellium once consumed. The majority of the lignin that rhino beetles cannot consume well would be broken down due to the digestive ability of the mushroom.

 
may ask what container u used for microwave? 
I mention this in the first part of the post, I use 16 oz deli containers that are microwavable. These are the same containers that everyone in the hobby uses to keep their larvae in. You can also potentially use ziploc twist on containers, and loosen the lid when you are microwaving it and letting the mycellium grow.

 
Do you mind sharing how you make your grain spawn without sterilization? 
I don't want to take credit for this, so I will link a video I used. You have to be very clean with when you do your grain to grain transfer and make sure the corn isn't too wet or else you will get wet rot (speaking from experience and based off what this guy says). You could also just try to use kinshi as sawdust spawn once you get those going as well. Grain spawn just grows way faster so its easier if you are trying to produce large quantities and want to use it for your own consumption.
