Yep, until they can just be left in the dark. But they indeed like a little light to trigger them when ready, though they do not feed on it like plants do.
I plan on harvesting their co2 and feed it to my cannabis plants.
The mushrooms can be eaten or used for medicine, as a by product.
Oh wow, never thought CO2 harvest was done this way. The kind of things you learn here. ❤️
