Hydrogen peroxide question

Is this actually good for my plant if i add it to my water i have a gnat problem and i heard i can use this to kill the eggs if so what ratio do i mix and how often do i use it and what are the harmfull or beneficial effects it can have on my plants. thxs for any input in advance

have you considered lady bugs? totally natural and they will eat the eggs. Or dragonflies are a natural predator of gnats.

Where do i get them its the middle of winter where i live, so is there a certain store that would sell them?

a garden store might , or a hydroponix store can order them for you. I have used them.

I gather that a certain amount of H2o2 Hydrogen Peroxide - trade names include Oxy, OxyPlus can have a VERY beneficial effect on the amount of dissolved Oxygen in your Res/Feed/watering solution, resulting in lush growth and big buds. the proportion added is critical, and if you add it at killing/cleaning/sterilizing strengths you will kill your girls I believe. Try a dilute soap spray, I do not think it kills, but they detest it, and bugger off somewhere else you can then rinse them with tepid water and foliar feed. I keep goldfish in my rainwater catchment, no gnats, no mosquitos no problem.

i hate fungus gnats! hydrogen peroxide is good at a few things. one is that it'll kill bennies in your medium. i use neem oil and sticky traps for gnats. a thin layer of sand over the top of the medium will work too.

thanks everyone for the help i got sticky traps and neem oil hopefully it will do the trick
