I saw The Dude was having fungus gnat issues in his last video on the SK progress. I’m surprised everyone forgets about using Diatomaceous Earth. We get fungus gnats here like crazy and my first grow here in coco it was a constant fight. Now every time I put a pot together, I’ll take off the top 1 inch or so of the media and mix in some DE then put it back on top. Since doing that I haven’t seen a single fungus gnat in my grows. I even do this now in my outdoor garden where I mix in coco and seems to work there just as well not to mention controlling a lot of pest problems out there.
