To soil or to septic is the question

Is it better for one to dump bad experimenting in septic or on the soil?

Ya, should have, could have, but didn't and have this growth that could do one or the other some good.
Question is which?

What sort of substrate / species?

Seeing as how this is under the fungi section, I am going to assume that you are asking if your should mold/fungus covered food/substrate in the soil/compost or if it should be thrown in the septic tank.

My default answer is to put it in the soil/compost. Unless you are doing some type of a breeding program/etc

First place it in a sunny dry area, where the unwanted fungus will be euthanized, then on to the compost pile for recycling...

If there is something about the materials that makes it unsuitable for burying directly in the soil or composting, then you could consider biochar, fermentation in something like bokashi bins, or dumping it in a barrel of water to let the bacteria work on it there... potentially a worm bin (or BSL or similar depending on what you may have and what the waste material is) depending on what it is and what is wrong with it.


I'm sure there are other potential options as well, but it seems like there are almost definitely choices available to you.

To me, any fungi or mushroom experiments that didn't work out would be best returned to the soil rather than dumping in the septic.

Maybe there was still some hope left in the fungi and one might reap the benefits of mushrooms in the compost pile.
