Thank you for viewing.

Limited Sale!!

This is a listing for 2 blocks of used Ohirataka mushroom substrate.

Please see the 20 photos above.

These are quite large blocks.

Additional blocks are available for purchase!

These are used substrate blocks made from 100% raw oak sawdust, offering excellent nutritional value.

As shown in the image, the mycelium is firmly established within the blocks.

Simply bury the blocks as they are in the substrate, and stag beetles will lay eggs!

They are easy to break apart, making larval extraction easier than with logs and allowing for a larger number of larvae.

Antaeus stag beetles are laying a large number of eggs!

It also enhances the nutrition for rhinoceros beetle larvae.

When raising rhinoceros beetle larvae, you'll notice a significant increase in size simply by burying these in the substrate.

They are also excellent as food for the larvae of stag beetles that prefer mushroom substrate, such as giant stag beetles, Japanese beetles, rainbow stag beetles, and Giraffa stag beetles!

They are also suitable for breaking apart to create your own original fermented substrate.

*The image is of one item from our stock.
