This is an easy way to spot contamination in your grains or substrate.
Take a Pic of your jar, bag, or bin.
Go to edit the picture. Put the brightness and saturation up to 100%
The colours our eyes cant pick up will show up.
This jar is an example from the OG group. Still have access if anyone wants me to search your name and can share a bit of your history 😉 😀
Happy Friday ladies!!!
