Hang some yellow sticky traps close to the top of ur medium because fungus gnats feed on ur plant's roots. If in soil u can apply a soil drench to kill the larvae in the soil, they're the ones that do damage. After the soil dries out u'll see a bunch of small rice shaped white things in ur soil. I believe its either their larvae or an exoskeleton left behind from metamorphosis. Neem is not that effective as a spray for fungus gnats. Mosquito dunks work as well as a product specifically made for them called Gnatrol , found at hydro stores (I've had success with the Gnatrol). Good luck. U can cover ur rockwool to prevent algae. I think ur supposed to do that b4 it shows up not sure. I'm a soil kinda guy myself. Hope some of this info helps u.
and it a natural product so my plant is still looking good. I like to keep thing s as natural as possible if i could help it.However my place still kindof stinks
How does that Gnatrol stuff smell? I was gonna try that tell i got some free pure Neem Oil from india. It smells old coffee with poo. but the place has been Gnat free ever since i opened the bottle lol. I don't think the gnat can thank the smell lol hell i could barely take it. The smell will last for at least 4 days. I do love the natural shine it leaves on the plant after use and Pure Neem oil is safe on the root. I pour some mixed with pure water in my medium (rockwool, worm casting w/perlite) to stop the eggs from hatching and i guess it worked. They say it takes 4 days for Gnat larvae to hatch and the gnats their live no more than 72 hours. its been almost a full week since i used the neem and im gnat free
