I recently added some spent oyster mushroom block to a mix of straw & boiled iris roots (boiled to help them break down faster because they are pretty much indestructible) & the mushrooms seem to love the substrate! Considering irises are poisonous, would it be safe to eat the mushrooms growing on them?
Sounds fishy. It smells fishy too. You say it's a tiny ad, but ...
