I've used H2O2 before in grows as a way to fight algae and fungus I didn't want. I found this link helpful when I was trying to figure out how much to use. I don't use it much anymore though, I'm into building up competitive beneficial microbiology instead of trying to destroy all pathogens.

Unfortunately, you don't get to pick the microbes that H2O2 will oxidise. It oxidises them all.
Competitive microbiology is all well and good I suppose, but in an inorganic-based hydro op, there should be one organism only- plants. I'm doing my best to grow and care for the plants. I'm not so good at playing sides in an invisible microbe war in my nute tank.

thank you for that scientific discovery, and wow peroxide 50/50 water kills all mold on your plant, epsom salt? wtf?? salt buildup...One day i drank i glass of water then later that day i threw up so water is bad for humans. I think ill start a thread

When I'm discussing "H2O2 50% grade", I'm talking about a product which is 50% pure H2O2 and 50% water.
H2O2 as found in pharmacies is usually 3%. 50% grade is found at hydroponics shops or chemical supply companies. 35% grade may also be used in hydroponics.
H2O2 is used in nutrient solutions, not sprayed on the plant. It kills mould fungi in the nutrient solution and in the rootmass.

It was probably not the hydrogen peroxide, it is working great in my airoponics system. I add about 1/3 to 1/2 a cup per day. To an 18 gallon tank. And u can add as much as 1 cup per gallon to water plants but i would not try this much myself. Because like you i don't care to loose my plants. also this is based on 3% peroxide not 33,50,70,or 90% the higher are used for rocket fuel.

Here are my two cents worth of experience with Hydrogen Peroxide:
My experience with H2O2 is with 35% from a hydroponic store, which I have used for about 15 years.
If you have plants that drain very slowly in soil, H2o2 will cure the problem. Plants that take five days to dry out in soil will dry out in 24 hours with a teaspoon of H2o2 per gallon in the water. Plants in soil can take more hydrogen peroxide without burning than plants in a hydroponic system because of the soil buffer.
In Hydroponics, when plants are small, H2o2 must be used hesitantly because you will burn them otherwise. I use about 1 tablespoon per 20 gallons for smaller vegetating plants with no problems. Hydrogen peroxide burns the little jagged edges of the shade leaves and in some cases the tips of the leaves if you over do it.
When plants are bigger in Hydro, I use two tablespoons per 20 gallons of solution with no problems.
If you have problems with algae growth on your hydroton or rockwool, add hydrogen peroxide when you top off your solution during the week. I add two tablespoons (for bigger or flowering plants) every time I top off my solution. Whatever algae you have will go away in a few days. Make sure you stir it in well so they don't accidently get a strong dose of undiluted to their roots.
If you have a sealed system, like an aquamist, I would suggest adding it when you first change out your solution and again midway between solution changes.
Hydrogen peroxide is awesome for cleaning out and sterilizing the system upon flush. When I clean out the system, I fill a five gallon bucket with water and add 5 or 6 tbsp of H2o2. I put my pumps and hoses into this bucket and run them for about ten minutes to sterilize them. I then use this water with a sponge to wipe down the whole system and sterilize everything clean as a whistle. I then fill the system, add two tablespoons of 35% H2o2 (to a 20 gallon system) and run it for a few hours to clean and sterilize everything, then I add my nutes.
It is best to err on the side of caution with Hydrogen Peroxide. A little too much can burn the shit out of your plants. I use very small amounts and get very good results. 2 tablespoons is about 30 ML which doesn't seem like much in 20 gallons, but if your system smells like fish tank water, the next day it will smell fresh as a daisy.
As far as bacteria are concerned, I could care less about them. I'm not into organics and just use the GH flora series nutes and get stunning results with no bacteria in my system. Of course, you might feel otherwise.
Don't spill it on yourself. Ouch. It doesn't burn for a few minutes but it eventually makes your skin turn white and burns like hell.

interesting. I have heard everything from 1 drop per gallon to 10ml/gal 35% peroxide every 2-3 days. Currently I am adding back at 5ml/gal to control pathogens in my hydro system.
I am going to tone down my usage next time just to see what happens.

H202 is great stuff used it for long while now and its great stuff. Don't use just store bought 3% peroxide as it has harmful additives in but use like grotek 35% super H202 at about 1 ml per gallon and let stand 2 hours before it pumps your system. Gives whiter roots bigger stalks and keeps the res clean. It kills the bacteria and infections in hydro systems. Onlky time not to use if your growing all organic as it can kill the organic microbs your after dong organics but it is great stuff.

AMEN BROTHA!!!!!! SING IT FROM THE MOUNTAIN TOPS FOR ALL TO HEAR!!!!

yes and for the added o2 boost which aides in root development which we know bigger root ball more yield and faster growth. I use 1-2 ml per gallon of grotek super H202 35%. Once per week at res change

My local hydro store stopped selling h202 recently and today I bought some food grade 35% h202 Im hoping its the same shit or just as good. Anyone use food grade? Also I found this later http://www.hydroempire.com/store/product_info.php/cPath/10_59/products_id/620
