## Sterile Technique Basics
- Work in front of a flow hood or still-air box  
- Flame sterilize needles/scalpels; cool before use  
- Wipe surfaces with 70% isopropyl; gloves on  
- Keep movements slow; keep talking to a minimum  

## Choosing Grain & Substrate
- Grain (milo/millet): fast colonization, clean shake  
- CVG: general bulk substrate for trays/tubs; not for wood-loving gourmet species  
- Master’s Mix: best for wood-loving gourmet species (oysters, lion’s mane, etc.)  

## Legal Note
We support gourmet and educational projects only.
