ive had my mushrooms growing for 13 days now. there is about 3 growing up from the sides of the box about 3 inches long. the only thing in the middle of the soil is about 2 mushrooms about 1/4 inch in size. is it okay to pick shrooms from the side of the box? if the ones in the middle arent growing should i pick them out? spray the box with water? im just worried about wasting future flushes. please help. thanks
