Limited Edition Sale!!

We are offering a set of 6 used Ohirataka mushroom substrate blocks.

Please see the 10 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 packed with nutrients.

As you can see in the photos, the mycelium is firmly established within the blocks.

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

They are easy to break apart, making it easier than splitting logs and allowing you to obtain a large number of larvae!

Ants are laying eggs prolifically!

They also enhance the nutrition for 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 the larvae of stag beetles that prefer fungal substrates, such as giant stag beetles, stag beetles, rainbow stag beetles, and giraffe stag beetles!

They are also suitable for breaking apart to create 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 misshapen or broken.

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