Biochar harmful to Black Soldier Fly larvae?

I have a small mix been colony of worms, red, earth worms plus black soldier fly Larvae. in a mix bin. it's where i get my Larvae in bulk. some parts of it is dry some parts wet and some parts have more hay mixed in. each live in a kinda mix bin zone. the key to it is putting the food waste mix with dried hay in the correct location and keeping the wet parts wet. again it's not perfect but it does work. my question is this i wanted to add biochar into my larvae bin. I have no test bin right now to try this out on and i don't want to wreck this. will the biochar hurt my larvae. im sorry if this is a stupid question it's just. i hate changing things around when i just got it somewhat working. but i reserved about 50lbs of coffee grounds and there's biochar already mixed in with it.

That sounds like one of those "it depends" kind of questions. I would guess (and that's all this is) that the char would do little to harm or help the bsf but too much of that mix at one time might alter the pH. The worms would probably like the fungi that would start to grow in it but not be as fond of too much char. I can tell you that I would add a bit at a time and see if anything avoids it. As long as there is plenty of other things added too, I would think it would do fine. Again... just a guess but worth experimenting with.

im gonna save the dried out spent coffee grounds with biochar at the end of the season it's already pretty much dry and not smelling . i think i can wait a few months to find out. thanks for getting back to me.
