everything came faster then expected. i can not wait till i get more supplies to keep it going. thank you

I had a small patch of mold pop up, I used this and a uv light and it abated never to return.

This additive is very effective. I highly recommend it.

Glad I found this, works as expected! Any mycologist should have this on hand.

This stuff works!! It stopped a 1" mold spot of green from getting any bigger and actually looks like the mycelium around the mold is whiter than before. I would keep this handy if you are doing a bulk grow. I had this express shipped!
