I did not know that. That’s why I come here! I knew that flashlight would help me find mold, I didn’t know a special light would kill it. Found a dozen or so on Amazon. Going to find a decent one with a timer.
I clean it and the filters every grow. I use windex on all 6 wall and surfaces, but I’ll swap out to a bleach solution.
Its mainly in the middle of the bud… like spider web individual strands or ‘hairs’ … I just want to make sure it’s not mould because I’ve just spent 1 year recovering from mold toxicity
Looks like your friends friend had a pet it sure looks like hair to me @Lela
