Black agar, aka MEAAC, is a nutrient-rich agar medium that has been dyed to a black color using activated charcoal powder. The black color offers exceptional contrast to growing mycelium helping cultivators to more easily observe mycelial growth.

What is Activated Charcoal aka Activated Carbon?

Activated charcoal AKA Activated Carbon is a fine porous black powder that is derived from organic materials such as hardwoods. To process Activated Charcoal, these organic materials are treated at high temperatures to break down the matter and increase the pore size.

Black Agar available in both Malt Extract or Potato Dextrose formulas.

Instructions for use:
