Okay spliff I'm going to do it tomorrow is the ratio that I'm going to attempt the correct ratio? One part hydrogen peroxide and 4 Parts water? Or should I try something different
i was advised to use it like that by a chemist but never got round to it, so wait for second/third opinions, there are many many posts on gnats btw
Can that product be used during flowering I'm 3 weeks into flower and I don't want to cause any harmI 2nd the Gnatrol! One low dose wiped out mine. Dilute peroxide won't do much good. Been there, done that.
Toilets and sinks that get regular use aren't a problem but a sump like mine was. The previous owner had left some malathion so I put a bit of that in there and sealed off the access. Bags of soil often come pre-charged with gnats that the adults got to while they were sitting around waiting to be sold. Most bags have little air holes in them and that's all they need or a tear in an otherwise sealed bag. Keep all dirt bags far away from the grow room. That means the kind dirt comes in too and not just your shady friends.
I happen to be a retired chemist but it's my many years of growing pot that have taught me all sorts of things like peroxide won't get rid of them. The peroxide will oxidize anything organic so when it's less than 1% it's already pretty weak. Might slow them down a bit but if used often it will also slow down your plants by oxidizing feeder roots too.i was advised to use it like that by a chemist but never got round to it, so wait for second/third opinions, there are many many posts on gnats btw
No problem. It goes in the soil so doesn't do anything to the buds. The adults don't harm the plants. They just mate and the female lays her eggs back in the soil and the male dies. Yellow sticky traps right in the pots can help get rid of the adults which eventually gets rid of the larva.
yeh sorrry this is the problem with the internet, too much misinformation and contradictions, was just reading an article on it last nightToilets and sinks that get regular use aren't a problem but a sump like mine was.

The best remedy is to get some Gnatrol or those mosquito dunks that have an effective bacteria in them targeted toward larva like gnats and mosquitoes. That stuff really works but if there is a source of new adults then it's an ongoing battle.
