Does it grow in the dark?
In nature these mushrooms grow in the shade of the forest, so inside light is about right. They are okay with a little sun, but be careful not to let this dry them out. Interestingly the UV in sunlight will help them produce victim D in a similar way our body does.
However, they do not need light to grow (as a plant does) so they are okay without light.
The myth of mushrooms growing in the dark goes back to when the French began the mass cultivation mushrooms in caves. This was because the cave had a constant temp and high humidity, rather than the lack of light. Not ironically they are called ‘field’ mushrooms they grow in fields …in full sunlight!
