best quick cheap cure for gnats right here

diatomaceous earth. i had gnats for entire grow tryed neem oil twice, worked for the mites but did nothing to the gnats. i tryed greensand but somthing got fucked up, maybe it threw the nutes off. well i bought some DE for 4 bucks and covered the pots, and im watching the fuckers die, fucked up wings, twicting and shit. they dont know what to do, id kill them with my hands but i know they are doomed anyways. i just got a couple lemons with vaseline in there too.

Great stuff,
I hope you used food grade and not the stuff you use in a pool. Your plant will not like that.
Either way be sure you dont breathe that stuff. Bad for the lungs.

from the hydro store, im sure it the right stuff, it looks awesome too like scorched earth

Go pick you up some hydrogen peroxide. 60cent a bottle..Mix it with the water when you water it its really good for the plants as well...

Yea, I know. I got a large container of it. Also known as shell flour cause thats what it is grind up sea shells.
Although I bought it to help with bugs I eat it (mixed with juice) too. I read the fibers scrape the inner wall of the intestine and clean your shit out. It also contains silica that improves skin, hair and nails. Just got to be careful you dont get it in your lungs.

Those fibers are what kills the insects, it scrapes there exoskeleton and they dehydrate.
