    Question Hydrogen Peroxide for flushing

    I'm seeking some help, I noticed yellowing fan leaves from the lowest part of my plants.

    The Earth box gets watered ever 3 days or so, I usually let about a gallon or just under trickle out.

    I'm thinking I should have flushed it better or something. I can't see the roots, so don't know if it's root rot.

    The only thing I can think of is flushing it with Hydrogen peroxide and give a half dose of FF Big Bloom.

    Any help on, how much HP I can use and is there more than one kind of Hydrogen Peroxide?

    Re: Hydrogen Peroxide for flushing

    There are different kinds of HP.

    The grocery store stuff comes at like 3%. You might be able to find 10% at a hydro shop

    Mixing varies, Im not familiar with earthboxes. With the 3% you can mix at 2 1/2 tsp per gallon. You might want to start out a little lower and work your way up.

    Re: Hydrogen Peroxide for flushing

    Thanks Billmoe,I found this on the web...


    To water or mist plants, to soak seeds, to add to water used to wash sprouts:

    TO THIS AMOUNT OF WATER ADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE --OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE
    1 cup 1 and 1/2 teaspoons 7 to 10 drops
    1 quart 2 tablespoons 1/2 teaspoon
    1 gallon 1/2 cup 2 teaspoons
    5 gallons 2 and 1/2 cups 3 tablespoons plus 1 teaspoon
    10 gallons 5 cups 6 tablespoons plus 2 teaspoons
    20 gallons 10 cups 3/4 cup plus 1 tablespoon plus 1 teaspoon
    bathtub (aprox 25 to 35 gallons) * 12 to 17 cups 1 to 1.5 cups
    * bathtub sizes vary. It is okay to use more water and/or less peroxide.


    I would like to get a couple more opinions though...

    Re: Hydrogen Peroxide for flushing

    Half a cup seems like a lot. Yea I would get confirmation before I did that ratio.

    Heres the article I got my ratio from. Ive used it at the stated ratio and had no problems and the plants seem to like it.


    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.

    Re: Hydrogen Peroxide for flushing

    Billmoe93:

    I like the H2O2 post. I would like to add or reiterate an important point you made about the free O attacking an organic substance. In Soil it is extremely important that gardeners realize the soil, once H2O2 is applied, loses all the good organic microbes that help bring nutrients to the roots. The soil is rendered as a base medium to grow in at that point. You must introduce water soluble nutrients from this point on to replace what the soil was doing. If you don't you will have roots looking for nutrients that are no longer present and your plant will show signs of malnutrition. In particular you may see the very tips of the cannabis leaves turn brown. Now you have to learn about water soluble nutrients because the ones that break down over time will not break down as there are no organic microbes to help break them down. As a soil grower it is better IMO, to transplant into new soil (same soil mix) after using H2O2 than to use nutrients you are not familiar with.

    Re: Hydrogen Peroxide for flushing

    how old is ur plants? why do u think root rot? xtrchessreal brings up valid point. i use 17.5% h2o2 for variety of issues, including tackling root rot. flush through with 1ml per litre of 17.5% H2O2 then after a few days run some weak water soluble nutes through. Then repeat with 0.5ml per litre of H2O2. and weak nutes few days after. u will then need to either transplant to new soil as suggested or ad beneficial microbes and fungi to the soil.
