Finding the perfect location for your mushroom kit can be a challenge. While these fungi can grow in darker areas, they do not need to be in complete darkness. Instead, they can grow well in indirect light. But keep in mind that direct sunlight can be fatal for your mushrooms. For that reason, it is important to find an indoor area that has the ideal amount of daily light. Often, an interior room will work well. Or you can place your mushrooms near a window, just close enough to receive indirect light. That light condition, along with proper soil moisture and humidity, will make your mushroom growing project a success.
