2. Robust Mycelium

The Ultimate “Compost” Growth Substrate comes Pre-Sterilized inside Professional Grade Grow Bags. Each bag has a:

i) 2-MICRON FILTER (to keep Contaminates Out and Fresh Air in)
ii) Commercial-grade IMPULSE SEAL (to Keep Your Bag Sterile)

Bags are available in 1-Pound, 2-Pound, 3-Pound, and 5-Pound increments. Be sure to purchase one of our 1-pound Premium Grain Spawn bags to easily inoculate your 5-pound bag of our Growth Substrate!


Everything is Handmade and Sterilized in our Professional Lab in Texas.

*Keep in mind that spores or liquid cultures are not meant to be injected directly into pure substrate. Spores or liquid cultures must first be inoculated into spawn and allowed to completely colonize prior to mixing into any pure substrate. If you have any questions, please ask before ordering

**Bag does NOT contain mycelium. Spores or cultures are not included. Our bags are ONLY for growing legal mushrooms. If spores are used only use spores from legal mushroom varieties.**

***Products are perishable and are best when used within two weeks of receiving.
