Maybe not as effective if using organics as you would need beneficials to break it all down before being available for roots right (wont make sense if it kills the good beneficials so far ive read it does not) im currently using pure vida organic that supposed to be ready available for roots to consume immediately im still curious bout this here Reef what are your experiences with this ?

When using H202 in grades higher than 3% -USE CAUTION -EXTREME CAUTION. This stuff will eat through your flesh once again it is a powerful oxidizer Rubber gloves, and Safety Glasses are a must if it falls on your eyes Blindness, I just want to make sure we get the point here. They have stopped selling this in California and Many other states because of the potential to use the explosive chemical reaction this stuff can give off, in the form of a huge bomb,(Homeland Security Bullshit)

Hydrogen Peroxide and Horticulture
By Bryce Fredrickson

Hydrogen Peroxide (H2O2) is a clear sharp smelling substance very similar in appearance to water (H2O). Like water it is made up of Hydrogen (H2) and Oxygen (O2), 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.

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. Pre treating the water supply with H2O2will 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.

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 color with dead tips or they easily pull away there is at least the beginning of a serious problem. An organic, ‘dirt like’ 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 viscous 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.

How Hydrogen Peroxide prevents root rot/over watering.
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.

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%) H2O2when changing the nutrient. You would then add seventy-five ml's more every day.

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.(there may be shipping restrictions on high strength peroxides). 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.

What to do if you already have root rot.

In Dirt:
Use peroxide water with an anti-fungicide and a high Phosphate fertilizer (9-45-15, 10-52-10, 0-60-0) for root growth. Or any other product with rooting hormone dissolved in it is helpful in regrowing roots and is strongly recommended. 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. Increase aeration of the water, get an air pump 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.

30 ml in 2-3 gallons is significant. As you said, if if was going to react with the PBP I would have expected it to have happened by now. Promising, hope it goes great.

I'd be interested to see a side by side comparison in any medium.

But generally I agree with Highroller. I've always been under the impression that the stray volatile oxygen atoms are just as capable of attacking a beneficial molecule as a nasty one.

Cusick you might be right take in mind beneficials thrive off oxygen like all living organisms h202 seems to benefit more than not ive read, and read somemore now all thats left is to find out for myself i mean how would one find out if h2o2 is killing thee beneficials without some science lab? ive recently been using White Shark beni'S i hope there not all dead! Wheres Reeferman? i would like to hear your take on thismy friend.......

"Dr. Lynette Morgan replies:
It's beneficial to add hydrogen peroxide (H2O2) to nutrient solution that's particularly "dirty"--that is, if it contains a certain amount of organic matter. This organic matter could be due to use of an organic additive. It could also be dead plant material, such as roots or algae. When H2O2 reacts with organic matter, oxygen is released into the system, which can benefit the plants root system. It's recommended to add 12-16 ppm of H2O2 to a dirty nutrient.

However, if the solution is reasonably "clean" and doesn't contain much organic matter, then a reaction won't occur and oxygen isn't released. And H2O2 can damage the living root system if there isn't any other organic matter present for it to act upon. Only add 6-8 ppm of H2O2 to a clean nutrient. This level prevents damage to the root system of sensitive plants while oxidizing any small amount of organic material that may be present. It will not kill pathogens at this level so is not a method of disease prevention.

H2O2 has been used for pathogen control in nutrient solutions, but the problem is that levels of around 100 ppm are required in order to control pathogens. And those levels can kill or severely damage young seedlings. Even levels of 10 ppm have been reported to reduce the growth of hydroponic lettuce crops. I suspect that the risks far outweigh any benefits of using H2O2 in the nutrient solution.

However, at levels of 200-500 ppm H2O2 can be successfully used as a water treatment in a separate tank for pathogen control. Then, after treatment, the water needs to sit for a specific period of time to allow the peroxide to drop down to a safe level before making up a the nutrient solution.

H2O2 can also be used in much the same way as bleach to clean the hydroponic system in between crops before replanting. Like when using bleach, always make sure that all system components have been thoroughly rinsed with plain, clean water before planting."

After becoming aware of this stuff while first reading this thread I done a bit of research on it as I couldn't quite get my head around all the info on it; So I thought I would post what I found here which may help some others that were feeling as confused as I was.

Hydrogen peroxide has been called a "kamikaze" or "depth charge" chemical against organic substances. H2o2 is simply water (h2o) with an extra oxygen molecule loosely attached (h2o2). When h2o2 contacts any organic molecule, the contact knocks off the extra oxygen molecule.

The result is two fold. First, energy is released. Though certainly not noticeable at the atomic/molecular level, the power in "decomposing" h2o2 is so great that hydrogen peroxide has been used to power rockets into space, powered the X-15 first subsonic jet and the U.S.S.R. supersonic attack torpedoes. When the atom breaks free, the kinetic energy holding that atom is released, resulting in a flash of steam heat. The first "killing" ability of the h2o2 is to blow up the organic molecule.

The free oxygen atom then impacts the organic molecule, resulting in burning the molecule. Organic substances in contact with pure oxygen "burn" (or more precisely oxidize. The combined result is that the organic molecule is blown up and burned.

What remains, then, of the hydrogen peroxide atom? It is now only pure water (h2o2) and pure oxygen (o). It destroys the organic substance and then converts itself to pure water and pure oxygen in the process. There are no toxins in hydrogen peroxide and it is the pure bio-degrading chemical that can not build up in your tank. It not only destroys organic contamination, but also destroys itself in the process to the two purest and most beneficial chemicals: pure water and pure oxygen. There are no other elements in hydrogen peroxide.

So H2O2 kills all organic bacteria whether good or bad.

Though with all that said I have found it can be used in combination with organic compounds when used in conjunction with an oxydator.


The Oxydator

How it Works:
It makes clever use of Hydrogen peroxide's (H2O2) chemistry. This molecule consists of an oxygen atom loosely attached to a water molecule, like a ball in a gutter. One "shake", (or impulse of energy), will set it rolling and this gives it special energetic properties. The "shake" is caused by a catalyst in the peroxide reservoir. Two peroxide molecules are needed to produce the water and pure oxygen.

The chemical equation is:
2 H2O2 è ( catalyst ) è 2 H2O2 + O2

The Oxydator causes this reaction in two separate stages: Stage 1 - A small catalyst rod breaks down some of the peroxide inside a plexiglass container, producing the exact amount of oxygen needed. A diving bell acts as a valve, while an air cushion at the bottom of the container prevents water from penetrating the unit.

Stage 2 - The specially developed ceramic of the Oxydator releases the pure oxygen. Only specialised ceramic can do this - ordinary ceramic has no effect at all. This two-stage process constantly regulates the activated oxygen, releasing the right amount and ensuring the concentration is never too high.

Oxydator Benefits:
Regulating the peroxide concentration has always been a problem. The Oxydator is designed with a constant, controlled release, giving the exact amount of oxygen needed at any time. It radically improves the water quality, giving all the benefits mentioned earlier in the thread. The key is a specially developed ceramic which breaks peroxide down completely into water and oxygen before it hits the water. But the Oxydator does not only provide a supply of fresh oxygen; Unlike ordinary aerators, it will not expel CO2, an important plant nutrient, from the tank. It also releases activated oxygen which detoxifies poisons, rendering them completely harmless.

Just found an Oxydator designed specifically for hydro. They seem easy to use and look like a pretty basic piece of kit so might be a worthwhile investment if they work as described me thinks.

Here is the product description:

Supplying oxygen to the root zone is vital for promoting plant health and growth. Unlike traditional air stones and pumps, the Oxydator creates 100% oxygen bubbles. This can only help to increase growth rates further!

The Oxydator produces oxygen through a specially developed ceramic catalyst in combination with hydrogen peroxide such as 'Essential OxyPlus', delivering 100% normal and activated oxygen in micro bubbles throughout your reservoir.

A self-regulating oxygen system, the Oxydator releases more oxygen through a ceramic catalyst if the temperature of the nutrient solution rises - when your plants need it most.

By changing the amount of Essentials OxyPlus (which you need to purchase seperately), you can also control the amount of oxygen delivered to your plants.

Simple to use, remove the acrylic container from the ceramic housing and fill it with the desired amount of Essential OxyPlus and distilled water. Add the catalyst to lock the ceramic housing. Finally, place the ceramic cover face down in the reservoir.

Benefits of the Oxydator:

- Supplies oxygen to the root zone, vital for promoting plant growth and health
- Oxygen bubbles detoxify harmuful pesticides, keeping the water in your tank clean, healthy and free from harmful pathogens and cloudy residue
- Releases extra oxygen when the water temperature rises - giving your nutrient solution more oxygen when it needs it
- Does not need electricity, and is silent and safe
- Simple to use
- Gives you control over the amount of oxgyen your plants receive
- Can be used with organic additives as it preserves beneficial bacteria or enzymes

Not entirely sure on that to be honest but I do know they can still be sourced from lots of places. I could be way off the mark but from everything I've read they seem like a relatively new product in hydro gardening.

Oxydators have been used previously in Aquariums as that was the technologies original application so you may be referring to those judging by the marinedepot site (the place I sourced the technical info on them). Here is some links, I hope they help (I put them in a code box as I'm not sure how Logic feels about linking). They come in 3 sizes and cost from £25-£65 on average.
