How much light do mushrooms need to grow?

Mushrooms need a very low amount of light to grow. Unlike plants, they do not like direct sunlight to grow so keeping them somewhere out of direct sunlight is essential. You can use small low wattage LED lights or fluorescent lights if you don’t have a suitable space to grow your mushrooms. A photoperiod cycle of 12 hours of light and 12 hours of dark will activate the fruiting of mushrooms once the mycelium is ready.
