Haven't tried the sand thing,.... Tho haven't had a problem with fungus gnats either


Diatomaceous earth might work too. And as an added benefit, it adds silica which helps strengthen stems if added early.
canniwhatsis Reviewed by canniwhatsis on . Little flying buggy thingy's I have had great success with Hot Shots keeping the likes of Spider Mites away. However today I spotted these tiny little flying bugs that are either on or in just the soil. They don't seem to be on the plants. I'm 3 weeks away from harvest. What are they? Should I be concerned? How do I get rid of them? Etc etc etc..... :smokin: Rating: 5
