Help with rot and h202

I have googled without an answer, can anyone who has experience with this please chime in?

I have root rot, i have cut off the majority of the slimy roots. I have 29% h2o2 and I would like to do a major dunk. Can I mix 50/50 water and h202? Just dunk em in and rinse em after? They are in 3 inch netcups. My main goal is do sterilize the hydroton and root cube and netcup while breaking down the rest of the slime. i have tried doing this with a weak solution i used 7ml per gallon, it didnt work. I have a buddy who did a quick dunk once but he cant remember the 5 he used. He thinks it was 50/50 but I would like more opinions please.

With 29% h2o2 I would mix it in the neighborhood of 3.5ml of h2o2 per liter of water. Put it right into the rez and leave it. Do this every 3-4 days and never stop. This is about double the concentration you used when you did it before and it won't hurt your plants. You'll like the results.

For sterilizing hydroton if you don't want to just buy more, I clean my hydroton in plain water and then put it in totes covered in water and mixed with 10ml per liter of h2o2 and water. I leave it in overnight and it's fresh and juicy the next day. Remember h2o2 breaks down in a fairly short time period and turns into water, so you can't just keep reusing the same juice to sterilize.

You can do a h202 dip but if you have root rot or slime, you need to look into why you have it.
What nutes you using? Does your res have a good amount of air going in it! What are your water
Temps!

And you should look into brewing tea this is the win all to slime! Heres a link

HydrogenPeroxide and Horticulture
Hydrogen Peroxide and Horticulture

Hydrogen Peroxide (H2O2) is a clear sharp smelling substance very similar in appearance to water (H2O). Like water it is made up of Hydrogen and Oxygen, however H2O2 has an extra Oxygen atom in an unstable arrangement. It is this extra atom that gives H2O2 its useful properties. H2O2 has been used for many purposes including cleaning, bleaching, sterilizing, rocket fuel, animal feed treatment and in addition many miraculous claims about its health benefits have been made. This article isn't about any of these; instead it will concentrate on horticultural applications. H2O2 is of great use for both hydroponics and dirt/soilless gardening.
1. What Does Hydrogen Peroxide do?
H2O2 is an unstable molecule, when it breaks down a single oxygen atom and a molecule of water is released. This oxygen atom is extremely reactive and will attach itself to either another O- atom forming a stable Oxygen molecule or attack a nearby organic molecule. Both the stable and O- forms will increase the level of dissolved oxygen. This is the method by which H2O2 is beneficial. Pretreating the water supply with H2O2 will drive out the Chlorine many cities use to sterilize it. This will also degrade any pesticides or herbicides that might be present as well as any other organic matter. Well water can be high in methane and organic sulfates, both of which H2O2 will remove. Many disease causing organisms and spores are killed by Oxygen, the free Oxygen H2O2 releases is extremely effective at this. H2O2 will help eliminate existing infections and will help prevent future ones. It is also useful for suppressing algae growth. The free Oxygen atom will destroy dead organic material (i.e, leaves roots) in the system preventing them from rotting and spreading diseases.
2.Over Watering
Roots require Oxygen to breathe and low levels are the main cause of almost all root diseases. Both soil and hydroponic plants often fall prey to the same syndrome although it is rarely recognized as what it really is. Hydroponic crops often fail due to "root rot" and soil crops succumb to "over watering." The real cause of both these problems is a shortage of Oxygen at the root zone. In a soil system the soil consists of particles, a film of water on the particles and air spaces between the particles. When too much water is put into the soil the air spaces fill with liquid. The roots will quickly use up what Oxygen is dissolved in the water, if they haven't drunk enough of the liquid to allow air back in to the soil spaces they will stop working. In this situation roots will start dying within twenty-four hours. As the roots die the plants ability to drink water and nutrients will decrease, this will cause symptoms of nutrient deficiencies (mostly pale, slow, weak growth), and strangely they will start to wilt like they don't have enough water. It is easy to make a fatal mistake at this point and add more water.
In a Hydroponic system the cause is a more direct simple lack of oxygen in the solution, this may be from inadequate circulation and/or aeration. High reservoir temperatures also interfere with Oxygen's ability to dissolve in the water. Temperatures above 70F (20C) will eventually cause problems, 62F-65F (16C-18C) is recommended. The same symptoms will appear as with soil plants but you can also check the roots. Healthy roots should be mostly white with maybe a slight yellowish tan tinge. If they are a brownish colour with dead tips or they easily pull away there is at least the beginnings of a serious problem. An organic dirtlike rotting smell means there is already a very good chance it is too late. As roots die and rot they eat Oxygen out of the water, as Oxygen levels are even further depleted more roots die, a viscius circle may be well under way. Reduced Oxygen levels and high temperatures both encourage anaerobic bacteria and fungi. The plants may still be saved but you will have to work fast.
3. How Hydrogen Peroxide prevents root rot/overwatering.
When plants are watered with H2O2 it will break down and release Oxygen into the area around the roots. This helps stop the Oxygen from being depleted in the water filled air spaces until air can get back into them. High Oxygen levels at the roots will encourage rapid healthy root growth. In a Hydroponic system H2O2 will disperse through out the system and raise Oxygen levels as it breaks down. Strong white healthy roots with lots of fuzzy new growth will be visible. This fuzzy growth has massive surface area allowing for rapid absorption of the huge amounts of water and nutrients needed for rapid top growth. A healthy plant starts with a healthy root system.
4. How to use it.
H2O2 comes in several different strengths 3%, 5%, 8% and 35%, also sold as food grade Hydrogen Peroxide. The most economical is 35% which we recommend be diluted to three percent before using, as at this high concentration it can cause damage to skin and clothing. When working with food grade H2O2 it is very important that you clean up any spills or splashes immediately, it will damage almost anything very quickly. This is extra important with skin and clothing. Skin will be temporarily bleached pure white if not washed cleaned. Gloves are strongly recommended when working with any strong chemical.
Food grade H2O2 can be diluted to three percent by mixing it one part to eleven parts water (preferably distilled). The storage container should be opaque to prevent light from getting in and it must be able to hold some pressure. If three-liter pop bottles are available in your area they are ideal for mixing and storing H2O2. There are twelve quarter liters (250ml) in three liters, if you put in one quarter liter H2O2 and eleven quarter liters (250ml) water in the bottle it will full of three percent H2O2 and the bottle can hold the pressure that the H2O2 will generate. Three percent Hydrogen Peroxide may be added at up to three ml's per liter (2 1\2 tsp. Per gallon), but it is recommended that you start at a lower concentration and increase to full strength over a few weeks. Use every watering even on fresh cuttings. For hydroponics use every reservoir change and replace twenty-five percent (one quarter) every day. Example: In a 100L reservoir you would add three hundred ml's (3%) H2O2 when changing the nutrient. You would then add seventy-five ml's more every day.
5. Where to get it.
35% food grade: called food grade because it has no toxic impurities
Of course your local hydroponics retailer, whom you can locate over the web at www.hydromall.com. Direct order off the web (there may be shipping restrictions on high strength peroxides). H2O2 is used to bleach hair so the local hairdresser may have a source. The local feed supplier may have it in small towns. Prices range from fifteen dollars per quarter liter to eighty dollars a gallon. One gallon will treat up to fifty thousand liters of water.
3%5%, 8%
Can be found at most drugstores or pharmacies, prices start at a less than a dollar for a one hundred-ml bottle that will treat one hundred liters.
6. What to do if you already have root rot.
In Dirt:
Use peroxided water with anti-fungicide (benomyl) and a high Phosphate fertilizer (9-45-15, 10-52-10, 0-60-0) for root growth. Root booster (5-15-5) or any other product with rooting hormone dissolved in it is helpful in regrowing roots and is strongly recommended. If a plant is wilty adding Nutri-Boost may save it. Water heavily until liquid pours out the bottom of the pot. This sound like bad idea, but it flushes out stagnant dead water and replaces it with fresh highly oxygenated water. Don't let plants sit in trays full of water, the soil will absorb this water and stay too wet. Don't water again until the pot feels light and the top inch or two of the soil are dry.
In Hydro:
Change your nutrients. Add H2O2 to the system. This will add oxygen and chemically eat dead roots. If roots are badly rotted and can be pulled away by hand you should pull them off. They are already dead and will only rot, causing further problems. Add a fungicide to kill any fungus that is probably present in the rotted tissue to prevent it from spreading. Root booster will speed recovery. If plants are wilty Nutri-Boost may help save them. Increase aeration of the water, get an airpump and air stones, or more of them, for the reservoir. An air stone under every plant is usually very effective, but will require a larger air pump. Models that will do from forty to four hundred stones are available. Decrease the reservoir temperature, oxygen dissolves better in cold water and disease causing organisms reproduce slower as well. A good temperate range is 62F to 65F; anything above 70F will eventually cause a problem. It is also a good idea to remove any wilty plants from the system and put them on a separate reservoir so they don't infect plants that are still healthy.
Summary
The key to big productive plants is a big healthy root system and Hydrogen Peroxide is a great way to keep your roots healthy. It is a must to ensure the biggest best crops possible and to increase the chances of your plants thriving to harvest. Peroxide users will rarely lose plants or crops to root disease and will harvest larger and more consistent crops.

thanks guys

johnny i did just what you mentioned and hellrazer if i decide to do a dunk, what ratio of the 29% and water would you use? Something in the back of my head is screaming 50/50...

50/50 water and h2o2 is highly likely to turn your plants into something resembling burnt french fries. For one time applications to the rez to burn off pathogens that are very out of control, or for a dunk, you could mix your h202 at 10ml per liter of water without killing them, but that's still only a 100-1 ratio.

Oops, I factored that with 35% h2o2. Using 29% you could probably up that to 12 ml per liter without hurting anything.

15 it is thanks haha

A root dunk in 25% peroxide would probably be quickly lethal to the plant, and any drops on your skin would leave nasty white spots.
The procedure for a rescue dunk that I've read but not personally tested is to make a 2% solution (so dilute 35% about 1 part in 16), dunk for 15 to 20 seconds, then immediately dunk in pure water.

For a reservoir dosing, the initial concentration guideline is .05% ... cn

10 ml per liter is a 100-1 ratio.

Rzza i dont recammened h202 dunking! You can do it at 5 to 10 ml per gal safley but rzza you need to go the way of tea bro

well i started a fresh rez last night with five gallon water, light nutes and 15ml of 29% h2o2. They looked ok through the evening but I awoke to most of them being quite dead looking. Tops are nearly touching the floor. It looks like they are all making lower case "f's", as if to say ffffffffffffffffffffffffffuckkk. haha I think they might bounce back and when they do I may just cut them at the base and re-clone. I have never had an issue but I was rennovating their room last week so I temporarily placed them in a tote and basically forgot about them. The tote is translucent a little bit plus they were in a warm place.

Hey rzza....

Awhile back I had root rot and I couldn't get product's for making tea....so I was able to get 29% H202 and some benny's called Activonate...I made up a 20ml per gallon of h202 and let it bubble for 3 hours....then I pumped it out and did it again for another 3 hours.....then I cleaned my buckets the best I could...Then flushed every thing with fresh water......then I added fresh nutes....... then I added the benny's...I used 4 teaspoons in a cupple gallons of water let it bubble for awhile....and then I split it up between my 6 buckets.....Then I had new roots growing in about 3 days....hope this helps........

My plants weren't wilted over when I did this but they weren't growing either..........nitro....
