Thank you for viewing.

Limited Sale!!

We are offering a set of 10 blocks of spent Ohirataka mushroom substrate.

Please see the 20 photos above.

These are very large blocks.

Additional blocks are available in any quantity!

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

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

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

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

Ante (likely referring to *Dorcus antaeus*) are laying eggs prolifically!

This 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 blocks in the substrate.

They are also excellent as food for the larvae of stag beetles that prefer mushroom substrate, such as giant stag beetles (*Dorcus hopei binodulosus*), stag beetles (*Prosopocoilus spp.*), rainbow stag beetles (*Phasmotaenia spp.*), and giraffe stag beetles (*Prosopocoilus giraffa*)!

They are also suitable for creating your own fermented substrate by breaking them apart.

*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, so the listing will end once sold out.
