Anything you read may be subject to the location and type of mushrooms being grown - they have to get the chemical mixes right or they mess up the shrooms, chuckl. If it is composted, it is well mixed and diluted, I use it the same as the other bagged stuff I throw in my beds or on the ground, 50/50 or roughly same and haven't had any issues. Logged compost, wow, gotta go see who imagined that into existence ( maybe accommodating a commercial machine)
