Thank you for viewing.

Limited Sale!!

This is a set of 4 used mushroom substrate blocks from Shiitake mushrooms.

Approximately 3000cc.

Additional blocks are available for any quantity!

These used substrate blocks are made from 100% raw oak sawdust and are packed with nutrients.

As you can see in the image, the mycelium is firmly established inside.

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 get a large number of larvae!

Anteaters are laying a lot of eggs!

It also enhances the nutrition for rhinoceros beetle larvae.

When raising rhinoceros beetle larvae, you'll notice a significant increase in size just 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, stag beetles, rainbow stag beetles, and giraffe stag beetles!

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

*The image is of one item from our stock.
Please only purchase if you understand that some may be slightly broken or have different shapes.

These are used substrate blocks, not for making mushroom jars.

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