Sterilized Rye Grain Mushroom Substrate in Injectable Jars (1 Jar Per Order) - Each Jar Has a Self-Healing Injection Port and a Filter

This did the job, no contamination and the inoculation was fast.

Usualy I buy these and wait for a week or 2 to see if any mold grows inside to check to see if the jars were sterilized properly. This jar passed the test. Well put together, well sealed, and the port holes are the correct size. I would recommend to anybody. Thank you

Thumbs up

Its finally colonizing. I had spores that wouldnt take and a month later tried new spores and now it is full of mycelium.

Seems like the bags aren't sterile the jars work very well

Excellent.

Grew nothing but bacteria

The jar was contaminated and This was a terrible product
