Hydroponic gardening - Hydrogen peroxide in the system

All Hydroponic gardeners should know about the benefits of using Hydrogen peroxide in the Hydroponic nutrient tank. Hydrogen peroxide is water with an extra oxygen atom in it which, when broken down into the solution, helps to add extra oxygen to your Hydroponic nutrient solution. This extra oxygen is then applied to the Hydroponic plant's roots making healthier and more robust plants with lots of healthy new root growth.

In Hydroponic gardening, Hydrogen peroxide is also very helpful in sterilizing your growing medium and the surrounding growing area at the same time. It helps to prevent bacteria and harmful pathogens like fusarium, pythium and some other unwanted diseases from growing in your Hydroponic system. When we first starting introducing Hydrogen peroxide into our Hydroponic systems we were amazed by the difference in the plants. We did experiments with Hydrogen peroxide in different Hydroponic systems side by side with everything identical in all systems including lights, temperature, nutrients and flood times.

When we introduced Hydrogen peroxide into some of the Hydroponic systems we noticed the difference in less than 24 hours. Our heads of lettuce all stood up higher and were much bigger and after 3 days they didn't even look like the plants without the Hydrogen peroxide, They were much bigger and fuller and looked like much older plants. We have been believers in H202 in Hydroponic systems ever since.

Let's look at all this in more detail and see why Hydrogen peroxide works so well in Hydroponic gardening systems.

Hydroponic gardening - Hydrogen peroxide in the system

In Hydroponic gardening, there are harmful bacteria strains that will thrive in low oxygen content water. If your Hydroponic nutrient tank solution tends to be usually on the warm side at 70 degrees or more, your Hydroponic tank and your Hydroponic growing medium is more likely to be a breeding ground for harmful bacteria and pathogens. This is because room temperature or warm water holds very little oxygen in it. The warmer it gets, the less oxygen it holds.

This is not a good thing in a Hydroponic system as these bacteria and diseases can spread very rapidly if you don't have a good supply of oxygen in your Hydroponic nutrient tank. It can cause root rot in the plants and as they rot they they will remove even more oxygen from the water. Use of a good air stone in the tank helps to supply oxygen into the water and also adding Hydrogen peroxide as well.​

Adding Hydrogen peroxide into your Hydroponic nutrient solution not only adds extra oxygen into the water and kills off harmful bacteria but it also will help to grow bigger healthier Hydroponic plants with thicker, healthier leaves and branches. Hydrogen peroxide also increases a Hydroponic plant's ability to uptake more of the nutrients from the solution as well.

Regular strengths of Hydroponic peroxide are 3% 5% and 8%. If you read the label on a bottle of regular household Hydrogen peroxide you will usually see that the inactive ingredient is purified water, which is good. This is like pure distilled water which is also good. It should say something else on the label though. It should say that the active ingredient is Hydrogen peroxide-STABILIZED. There has been much controvery on whether or not stabilized Hydrogen peroxide is good for the plants so let's dicuss that.

Stabilizers are added chemicals that stop the product from beaking down on the store shelves. Although we usually want to know exactly what we are putting into the Hydroponic nutrient tank we have used regular 3% Hydrogen peroxide that you can buy in any store with never any ill effects on any of the plants. We have used it in strengths from 4 tablespoons per gallon of water up to 1 whole cup in a 12 gallon Hydroponic nutrient tank with no problems at all.

Adding 2 to 3 ounces a day to a five gallon tank has also been done. The plants all seem to grow great and very heallthy with no signs of any bacterial growth anywhere. We know of many other growers who use it also with no problems to the plants. Always store any Hydroponic Hydrogen peroxide solutions in dark or light proof containers. Light rays break it down which is why it is sold in light proof bottles to start with.

The plants usually tell us everything we need to know about what we are doing in Hydroponic gardening. I would say that if you get some burning or yellowing of the leaves in your plants to reduce the amount or the strength you are using as it may be too strong. You can also make up a 5 gallon bucket of water with about 500 PPM of 3% regular Hydrogen peroxide and use it to top off your Hydroponic nutrient tank when it is low. This is a good practice to help keep your plants healthy and your Hydroponic nutrient solution bacteria free.

​

Hydroponic gardening - Hydrogen peroxide in the system

Hydroponic stores carry other forms of Hydrogen peroxide available that has been made with no stabilizers and is actually more cost effective to use. One popular Hydroponic product and probably used more than any other is a 35% strength food grade Hydrogen peroxide that can be diluted down to a safe Hydroponic usage level.

To get a 3% Hydroponic solution you would mix this Hydroponic product at 1 part of the 35% Hydrogen peroxide to 11 parts of water. This is strong stuff and it can burn your skin and other things also. Mix it in a separate container with gloves on before adding it to your Hydroponic tank. This 35% Hydroponic food grade product is also used in drinking water for farm animals to help reduce the bacteria in the water they drink so you may also find it at farm stores. Some beauty salon supply store also have it for bleaching of the hair.

When used in Hydroponic systems, Hydrogen peroxide also helps to eliminate the chlorine making the water more pure. It makes strong healthy white roots with lots of fuzzy new growth in Hydroponic plants. This, in turn, allows the plants to absorb more of the Hydroponic nutrients and gives faster overall growth.

Using Hydrogen Peroxide in your
Hydroponics Gardening System



There are no doubts about the benefits of using hydrogen peroxide properly in a hydroponics system. This becomes especially true if your nutrient reservoir is kept above 72 degrees. Warm water holds less dissolved oxygen, and therefore encourages the growth of more viruses, fungi, and anaerobic bacteria. Using hydrogen peroxide adds oxygen to you water and cleans the water of pathogens. Benefits include healthier root systems, increased nutrient uptake, thicker stems, and bigger leaves.

One expert claims it should be used on all soil gardens as well as in hydroponics sytems. Knowing as much as I do about beneficial fungus and micro-organisms and the benefits they provide to living plants, I am shy in taking this advice. However, when this first line of defense fails and plants become sick I often resort to using hydrogen peroxide treatments on my soil grown plants.


The chemical formula for hydrogen peroxide is H2O2. You may notice it is simply water with an extra oxygen atom. In fact, as hydrogen peroxide breaks down in a solution the result is oxygen and water. Its application helps deliver oxygen to over watered plant roots and helps to sterilize the growing media by killing harmful anaerobic (not oxygen compatible) bacteria and pathogens that cause disease. This includes bacterial wilt, pythium fungi, fusarium fungi, and others.



Using 3% Hydrogen Peroxide
In your Hydroponics Garden

I avoid using hydrogen peroxide you commonly find at drug stores. This is because such low percentage (3%) solutions are unstable, and chemicals are added to the peroxide to keep it from breaking down before it can be used. I did a little research because I did not know what chemicals were used for this, or if the plants uptake these chemicals, or if there was a health risk associated with any of these stabilizing chemicals.

Hydrogen peroxide is usually stabilized with acetanilide. Acetanilide is a synthetic compound that was first used for its fever reduction and pain killing properties in the late Nineteenth Century. For many years it was utilized as an alternative to aspirin to treat various ailments, but large scale medical use stopped when the toxic side effects of consuming acetanilide became apparant. This was enough to convince me to use 35% hydrogen peroxide instead.



Using 35% Hydrogen Peroxide
In your Hydroponics Garden

Firstly, 35% peroxide is caustic and should be treated with the same caution as a strong acid. 35% strength hydrogen peroxide should be readily available at any quality hydroponics supply shop. The stronger concentrations do not use the added stabilizers.

The recommended dosage is to add 2-3 ml to each gallon of water, however, I use 5 ml per gallon and have never had any problems. At every nutrient change treat your fresh water using hydrogen peroxide. The general idea is to let the hydroponics system circulate the hydrogen peroxide solution for about a half hour to let the peroxide work against pathogens and to let the solution stabilize before adding your nutrients.


The beneficial effects of using hydrogen peroxide last about 4 days. There are some gardeners who add a little peroxide to their nutrient reservoirs every 5 days in between nutrient changes. If you decide to do this, stick to the guidelines and always make sure your solution is thoroughly mixed before exposing your plants roots to it. Another option is to top off your nutrient reservoir with peroxide treated water whenever it is low.

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 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 12 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.

Uh,, some say its OK to use 3% and some don't, thoughts?

 

[mr. green thumb 01]

is it safe to use with organic nutes?

 

[Gixxerboy]

is it safe to use with organic nutes?

I have never used organics so I can't say from experience.I don't see why not.It will increase oxygen levels, kill algae,but will also kill beneficial bacteria.

Well surfing around found this product H2o2 OxyPlus witch most of the time products like these are 35% HP but I dont know what else.Its description does state a warning about organics!



For maintaining optimum oxygen levels in the nutrient solution. Many customers prefer to use Oxyplus instead of an Airpump/stone. Not suitable for use with some organic nutrients..always check prior to use. Oyxplus also sterilizes the nutrient solution to leave it free from harmful Pathogens.

A useful solution for the clean up of systems & grow room post harvest !

I am only going to use 3% solution or try it I guess...I use flora nova so well see what happens. I am going start off small with 1 tsp a gallon.

Just to give a different view, From the DM website

Commonly known as H2O2, is intended for cleaning equipment and treating well water only. Often, it is sold on the premises as "extra oxygen" for roots. H2O2 is a highly reactive molecule. It is an oxidizing agent that is unstable in solution and tends to rip away electrons from other sources such as living matter (including root cells, bacteria and your skin!!) and chelating agents as well as reacting with other organic matter. This is what makes it an effective "cleaning" agent. However, for this reason it is not recommended in root zones or nutrient solutions. Adding too much H2O2 can kill your plants by damaging the roots, and render 'Hydroponic Nutrient Solutions' less effective by breaking down chelating agents.

It is recommended that you follow label instructions on dilution rates and treat water beforehand with H2O2 and allow at least 24 - 36 hours for most of it to react and become water and oxygen. Then use this "sterilized" and oxygenated water for your nutrient solution.

On the other hand, I've used 3%, bottles at a time, and even sprayed it directly on the roots many times when fighting disease, without obvious ill effects. I find it is nice to use with a sterilizing agent to keep things nice and clean. However, some DWC people find keeping a sterile res is impossible, in which case you have to use bennies, which makes h202 a bad idea.

[Icannabis]

I stay away from H2o2 in my DWC. It seems like a good cleaning agent for equipment but as far as that. I use Dutch Masters Zone or SM90 I recommend these products. But everyone has different opinions on it. Just on 2 cents. Good luck

Thanks Icannabis,I also have been looking at water treatment products that contain HP these two I have not came across yet.This would be a great place to start listing them for everyone to see as you have started the list off nicely with your two examples.Nutrients are easy to locate but water treatment is rarely discussed i find.

Hello.
I have been using oxy-plus in my system for the last month. Been using it about once maybe twice a week(cost stops me using everyday). not had any problems with it.

i have a 30 litre dwc bucket, four 4inch air stones, 20L\hour air pump, in a dr 120 with a 600w hps.

Res temps have been getting into the mid 20's and oxy-plus seems like a good preventative measure,i like to keep my res 18-20c.

i use advanced nutes G\M\B and hammer head, so no organics for me. From what i hear h2o2 kills mychorizae
and such benificial bacteria present in organic nutes, so i couldnt recommend using such products together.

i use the recommened dose on the bottle 5ml per 10 liter so 15ml for the tub when topping up res and nutes.
h2o2 only lasts a 3-4 hours at best in your system, after that its inactive so you could nute up after h2o2 or inoculate then,if using organics.
I'm no expert but have been chatting with a friend who's currently studying bio chemistry, he reckons its ok.

Find ur self a bio chemist they no everything you need to no

fing awesome! killed bugs in the res? or on the plants? Can you spray peroxide directly on the plant to kill bugs I.E MITES!?

Yes in the res,I don't know or think you can spray it directly on the plant itself.Roots i know for sure yes, plant tissue probably would not like HP very well.Hairdressers use 35% to bleach hair i bet it would do some serious damage to leaf tissue.I cant say form experience but this is what I'm guessing.Mites I have never had found this on our own site


byLunesta215 Floramite its the best and will stay in the plant for up to 45 days. I had a bad infestation and this is the best stuff. I think its 30 bucks or so. But by all means get it



by Black Light



by MrFishy Pyrethrum - Wikipedia, the free encyclopedia

I use a pyrethrum based product called "Eight" . . . can be used up to one day before harvesting.
I wouldn't spray it on my buds, unless they were just starting.
For mites, no matter what you use, you'll likely want to spray twice . . . once to kill off the adults, again in 2-3 weeks to kill any hatchlings.



by capncash Hot shotz no pest strips are the bomb for spider mites



by itsamedicalnee I would just use this http://www.defenders.co.uk/pest-solu...e-control.html They sell other insects that will kill the spider mite.



by slamminsalmon i put a jar in the freezer for a couple days, and i took it out for a couple hours to let the moisture evaporate off the sides of the jar. believe it or not i actually saw some climbing up the sides of the glass after the first night. so thats why i chose to do a couple nights.just keep and eye on it. it worked fine for me.



by proheto8008
There is some shit from australia that is fairly new. Spider mits dont have a resistance to em. THis stuff is def the way to go. Ive only had em once, but this shit knocked em out quick.

just became available in the U.S. recently. Im hearing guys talk about how amazed they are that this shit works. My buddy got mites, and he battled them for a year in his garden before he finally just moved. He got em again, and used this shit and they were gone after one application.

heres some shit from the site

http://verticalhydro.com/index.php?m...8206094d991ed5

Spider mites destroy plant cells by sucking out their contents, and Mite-Rid works by providing a barrier which is harmless to the plant, but fatal to the mites. Some of the components of Mite-Rid are also absorbed by the plant and then suppress the life cycle of the mites. Mite-Rid uses a unique formula of botanical oils, including neem, garlic, eucalyptus plus surfactants to provide a protective barrier against many leaf eating pests, and most effectively, the Spider Mite.
The main active ingredient, neem oil, contains a limonoid called azadirachtin which has steroids (campesterol, beta-sitosterol, stigmasterol) which interrupt the normal hormonal balance of mites, suppressing its reproductive cycle. The neem oil used in Mite-Rid is cold pressed, as only oil of this quality will contain these steroids.

Mite-Rid is fully bio-degradable and is not toxic to animals and under normal use will not affect the plant's metabolism. Highly effective against two-spotted and red mites, Mite-Rid is also reporting success with Eriophyid mites such as the "Fuschia Gall Mite" which is endemic to parts of California and also known as the "Mendo" or "Mendocino mini". Mite-Rid comes in a concentrate form, and the 45ml bottle mixes with water to make 18 litres ( 32.7 pints) of mite killing spray.
One thorough application is usualy enough, but heavy infestations may require two, as the tiny eggs can be a bit more resilient; so we recommend a second application in these cases.
Get them before they get your plants!

They say prevention is better than cure, and just a little Mite-Rid goes a long way to preventing mite infestation. A periodic spray with Mite-Rid is the best way to never see your plants suffering an attack of spider mites.
Remember, when it's hot, and dry, mites are just a gentle breeze away from your plants, and they usually go undetected until they've multiplied to plague proportions. Just one spray every few weeks in the hottest season will protect your crop from this near invisible pest.
Whether you're an indoor grower, greenhouse grower, hydroponic grower, or outdoor grower, sooner or later the mites will find you!

Don't wait to see the damage,
get them BEFORE they get your plants!​

I used this shit because i had an infestation early. I read about it on a forum and got some. (i was lucky cuz only one retailer was even selling it in the u.s. at that point, and he had just started a month prior)

After one application everything was gone.

give this one a try if you got the mites. THIS SHIT WORKS!
