Product Details

This is a set of 4 G- S size, 900cc mushroom substrate bottles, ideal for raising larvae.

The wide diameter allows for use with larger larvae.

Suitable for:
- Male Giant Stag Beetles (Ookuwagat)
- Male Rainbow Stag Beetles (Nijiiro Kuwagata)
- Male Elephant Stag Beetles (Futamatakkuwagata)

For stag beetles aiming for Guinness size, we recommend bottles with a larger diameter.

Since it uses Shiitake mushroom substrate, it is suitable for most major species (excluding those that prefer Kawara substrate).

★★Additional bottles can be added for ¥600 each, up to 2 more★★

- Capacity: 900cc

- Ingredients: Oak, Shiitake mushroom

●Main Material: 100% Domestic Raw Oak
The oak logs used for the sawdust are selected for their suitability for white rot. No other wood types are mixed in. Additionally, bark contains a high amount of tannins, so thin logs and branches with a high proportion of bark are not used.

●Secondary Materials: All Natural Materials, Natural Water Used
Carefully selected fresh natural materials are used, tailored to the physiology of larvae. No synthetic chemicals are used. Natural water (collected from an altitude of 367m in the Koya-san mountain range) is used. High-pressure sterilization (120℃) is performed, and no pH adjusters are used.

Thank you for viewing.
