Fungus Gnats are mostly see-through pests that are usually found on the upper roots. Fungus Gnats, if left unchecked, can spread throughout the root system. If allowed to progress far enough, these pests can easily destroy thousands of dollars of product.
Once a crop is destroyed by fungus gnats, the nightmare isn’t over. Their larva and other pests like to hibernate while there is no weed for them to eat. This makes it crucial for growers to deep clean an area (indoors and outdoors) after an infestation. Especially before the next grow season.
To slow down the gnat’s reproduction, try keeping the humidity and watering low and make sure nothing becomes too soggy. Covering hydroponic medium surfaces will also prevent green algae from forming which is their favorite place to nest. Check your roots to see if they are damaged because damaged roots are a really good source of nutrients for these pests as well. Be sure to keep up with keeping your plant healthy, happy and pest free!
