The Cinammon has worked, haven't seen one it 2 days.

See what I mean. Nobody seems to want to tell me what to do, which leads me to believe they don't want to be responsible for the aftermath.

Thanks but which one do I use for fungus gnats? Do I do it once, or everyday, or twice a week?

Dude....I have about a liter of 3% h202, that's not the issue. The issue is nobody seems to be able to tell me what the proper dilution rate is to use it. How much 3% household hydrogen peroxide per gallon? How will this kill the gnats if the nutrient solution doesn't even kill them?

I heard cinnamon mixed with your soil works, so I sprinkled some in the saucers the pots are in. It smells good also. I have a container with some soapy water, hopefully they will take a bath in it and I have one yellow sticky fly trap hanging. If they persist in a few days, I guess I'll go...

They feed on fungus, that's why they are called fungus gnats, lol. Where the drain holes are in the pots, is where the slimy fungus grows, because it get's light and stays the wettest, I guess. It's never been a problem before, I've had fabulous results with this container and medium.

I searched "fungus gnats in rockwool" and can't find a single person that recommends peroxide, so I'm hesitant to do that especially since I only have household peroxide and don't know the proper dillution to use it. How do I apply the neem oil to the rockwool? I'm using loose rockwool in 1gal...

That's great, but it would help if your replies actually answered my questions.

So 3% is household hydrogen peroxide? Just spray it undilluted on the top of the rockwool? The thing is I have covers on the tops, the gnats seem to fly out of drain holes on the bottom of the pots. Can someone else confirm this is safe?

I have a sticky trap. Can I use household hydrogen peroxide? I was thinking to mix it in the water and water the plants with it. I don't see how they can even live in fertilizer solution, is it possible?

Hi, new here. I tried to read the "look here first" in this section, but I can't view any of the pictures, anyone know why? Anyways, I have these flies coming out of my rockwool, I think they are fungus gnats? Anybody know a way to get rid of them? Never had this problem before. Thanks
