Could Your Coco Be Part of Your Aspergillus Problem?

When cannabis repeatedly fails Aspergillus testing, operators often focus on the flower, grow room or sanitation program.

But there is another part of the cultivation system worth evaluating:

The material your plants are growing in.

Coco coir is widely used in commercial cannabis cultivation.

That doesn't mean coco is automatically responsible for an Aspergillus failure.

It does mean growing media should be included in a comprehensive contamination investigation.
