Had a shit ton of fungus gnats in my grow tent. Using coast of main stonington blend in 3 gallon pots. Tried Neem oil and sticky traps and still had issues. Using supersoil so wanted to try to stay organic so tried a few organics insecticides. Still a lot of gnats. Made sure my moisture was in check, and cleaned the whole tent. Bought some diatomaceous earth planning on trying that tomorrow.
1 any suggestions?
2Is it possible to put Hydroton on top of solid in future grows to keep gnats off of the soil?
3. Plants are still growing good but get some occasional “eaten leafs” haven’t really seen anything about gnats eating leafs but haven’t seen any other critters.
May add some fresh soil to tops of pots can I mix the diatomaceous earth into the added soil or does it have to be a layer on top?
