This is a fermented substrate made from the highest quality Himalayan King Oyster Mushroom mycelium, using 100% oak sawdust, which stag beetles prefer most.

We've further refined ordinary Himalayan King Oyster Mushroom substrate into fine particles for easier consumption, and added 3 times the amount of nutritional supplements such as trehalose, glucose, chitosan, royal jelly, special amino acids, and symbiotic bacteria.

We do not use any discarded substrate. Instead, we crush fresh sawdust into substrate and ferment it slowly indoors.

This is our ultimate, meticulously crafted substrate, fermented three times with significant cost and time investment.

Most other companies' fermented substrates use discarded substrate, leading to the presence of miscellaneous insects and fruit flies. However, our substrate is completely free of miscellaneous insect contamination.

Thanks to the consistently large individuals produced, this substrate has a very high repeat customer rate.

Even with the same mycelium, substrate finished with Himalayan King Oyster Mushroom mycelium is most preferred by stag beetles and results in larger individuals.
Himalayan King Oyster Mushroom is expensive and difficult to obtain.

It can be used as food for the larvae of all types of stag beetles, both domestic and foreign, and as a laying substrate.

It is suitable for Miyama Stag Beetles and Sawtooth Stag Beetles.

You can also raise Sumatran Stag Beetles, Giant Stag Beetles, and Rainbow Stag Beetles with this substrate.

Naturally, it can be used for all types of rhinoceros beetles.

The substrate is made by crushing and fermenting fresh sawdust, and it contains 3 times the normal amount of nutritional supplements, resulting in outstanding nutritional value.

The key to raising large adult stag beetles is to feed the larvae plenty of high-quality food during their larval stage.

Our high-calorie, nutritionally outstanding Himalayan King Oyster Mushroom Premium Substrate is the pinnacle of larval food.

Guinness-sized Miyama Stag Beetles have been produced.

It is more versatile and economical than using mushroom bottles, as you can fill jars or small cups with it.

We regularly receive orders from stag beetle shops nationwide and have received high praise.

Some users of this fermented substrate have won top prizes multiple times in Be-Kuwa contests.

Not only is it excellent for feeding larvae, but it also results in a large number of eggs when used as a laying substrate.
