Ya but I just love using lead dust as an additive!
Naw but I mean purely as a means of bioremediation and not necessarily for the safety of home cultivators.
Cubes are hardy and are not too finicky with their environmental factors, so they could be good candidates if they do.

My agar is died yellow and doesn't alter mycellium at all.

Pastywhyte said: I really don't know. Something to look into as its certainly possible. While nothing has probably been done with research on cubes in that respect but we could look at some similar species. Or I suppose one could simply do what they could to ensure a heavy metal free substrate for them 
I know one thing you shouldn't do if you want to keep your grow area free of heavy metals.
Don't play this.

I've heard about the heavy metals, not sure if it applies to cubes or not. Seems safer to assume yes but we don't really use heavy metals in our substrates either.
Well, hydrocarbon *based* but obviously have enough crap stuck onto them to have a charge. Food coloring is soluble in water, after all. They probably do that so it works in oil and water, at least that sounds good, I guess 
If the mycelium will take in the water and the dye is small enough to go with it (which it should be) it's then absorbed. I'm not gonna say for sure though they can't digest it. When fungi decomposes polyurethane and can live off only that it makes me question these things 
Re: heavy metals -- this is more enzymatic destruction by redox reactions, for example the laccases, which neutralize magnesium and other heavy metals. I don't think copper is, as it is toxic to most fungi. (Cu is weird anyway; I believe it is normally chelated in digestion and absorption in other kingdoms).

Well, all I have to go off of is putting a few different food colors in agar and watching the fruits come off of that. I haven't tried anything that wasn't deemed food grade, which I imagine is where all these other things would fall under.

Yep. I dunno how I forgot to mention but the black dye.. I guess it's really just super dark green or whatever, but anyway, that DOES absorb into the mycelium. Seems to slow it down some, and it makes it look a little weak. I don't know if I have a picture of that happening...

That's the agar but I can't seem to find the mycelium picture... someone else reported the same results.

Dark green to black and slowed mycelial growth?
Could it be this? I know Cu is toxic to fungi to an extent...

I dunno, would that be in a food coloring?
