yo brother, if ur having Fungus Knat problems. Go to the hardware store or farming center and buy/get some "PLAY SAND" yeah dont get ne ideas and play in it. Ne who, pour that shit out all over the top or your potting soil in your pots and fill em up about a half inch to an inch. The reason for doing this, is that the Fungus Knats cant burrow through it cause its too heavy, but when you water/feed it can! Good Luck
