Thank you for viewing.

Limited Sale!!

We are offering a set of 20 used Ohirataka mushroom substrate blocks.

Please see the 19 photos above.

These are very large blocks.

Additional blocks are available for purchase!

These used substrate blocks are made from 100% raw oak sawdust and are highly nutritious.

As you can see in the photos, 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 it easier to extract larvae than with logs, and you can obtain a large number of larvae!

Anteaters are laying eggs prolifically!

They also enhance the nutrition of rhinoceros beetle larvae.

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

They are also excellent as food for larvae of myceliophagous stag beetles such as giant stag beetles, Japanese stag beetles, rainbow stag beetles, and giraffe stag beetles!

They are also suitable for breaking apart and creating your own original fermented substrate!

*The photos show one of the items from our inventory.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.

This is a limited sale, and the listing will end once sold out.
