The Maestro’s All-In-One Bag is designed for simplicity and reliability.

Each 5lb bag contains 2lb of sterilized grain made from wild birdseed and 3lb of nutrient-balanced substrate composed of coco coir, vermiculite, gypsum, and aged horse dung courtesy of Pepper — our resident farm supplier.

Bags are prepared in a double-sealed mylar bag with a micron filter patch and self-healing injection port, allowing for sterile handling and ease of use in microscopy and research workflows without additional transfers.

Suitable for both beginners and experienced researchers.
