Fungus gnats look like tiny flies are buzzing around cannabis plants, particularly around the soil. Their larva grows in wet soil, and sometimes they appear when the topsoil stays wet for a very long time between waterings.
Solutions for getting rid of Fungus Gnats:
A fungus gnat is very tiny and it’s thinner than the width of a quarter. These generally appear when marijuana plants are too often watered. Fungus gnats most often naturally go away on their own, if you let the top inch of your soil dry out before watering your plants each time. However, if you are having a really bad infestation, before you get rid of all of them it can take weeks of good watering practices unless you also do something to directly killing off the bugs and bring down their numbers.
