So I'm about to restart my grow cycle. Last cycle we had a fungus gnat problem, hoping to avoid that this time around. Local grow store suggested the following tip for dealing with larvae in mature plants. He said this:
"Increase o2 levels from 1.5mL per 4litres to 5mL per 1 litre."
I'm just wondering if this is safe? My o2 is 29%. He said my plants would be totally fine, but using over 13x the recommended o2 levels seems scary to me.Any input would be greatly appreciated.
So my real problem comes with trying to keep the fungus gnats away from my seedlings. I cannot hit the young guys with o2 because they are way too young. Grow store told me to make sure I don't over water and it should keep the gnats away from seedlings. Apparently neem oil isn't sold in Canada. But he promised me o2 would work just as well.
I've read that putting a layer of perlite at the top of the soil slows them down. I'm also gonna pick up some yellow sticky traps, and probably set some apple cider vinegar traps to catch the adults. Any information at all on controlling these gnats would be greatly appreciated. Cheers and happy growing!
