Ideas for hydrogen peroxide

Discussion in 'Growing Marijuana Indoors' started by TexarkanaTim, Jun 5, 2009.

  1. Howdy all.....I was just doing some random browsing on gardening techniques and tips, and ran across some pretty in-depth info about using hydrogen peroxide. An old fellow named Bill Munro uses it in his garden for soaking seeds, watering plants, foliar spray, and pest control. He even puts it in a nasal inhaler and inhales it daily! Anyways, I read some of his claims and they sounds pretty good. Faster seed germination, bigger plants, and higher yields. And best of all, its organic and chemical free. Thought it might be something useful for people to check out. If you Google the name Bill Munro, it will lead to his info.

  2. Interesting. I'm going to look into that. Thanks! +rep.
  3. Hydrogen peroxide is manufactured but yeah i've heard of people using diluted h2o2 to treat root rot because it's a fast oxidizer.
  4. Yeah I've also heard of people gargling this stuff after they brush their teeth.

    As a kid I would always put some on my scrapes and cuts, and watch the bubbles.
  5. if you add H2O2 to your water it increases the oxygen levels, its a good idea and im going to be doing it
  6. Yeah..H202 is good for stimulating root growth because it adds oxygenates the nutrient solution. But you wanna make sure you Get FOOD GRADE H202 (can be bought at any hydro store or most plant stores) food grade H202 is 30% by volume, and has little to none impurites. the kind of H202 you buy at the walmart or the drugstore, is only 3-10% by volume and has more impurities in it.
  7. H2O2 is mainly mixed in with inorganic hydroponic nutrient solution. I use the 35% grade at 1ml per litre of nutrient solution. Algae, pathogen and root rot is a thing of the past with me.
    Without a doubt, i would recommend it to any inorganic hydro grower.
  8. Does it kill the good microbes in organic soil?
  9. No, they like and need oxygen.

    Deliver H202 to your roots, for all reasons others have stated. But do not spray it on your plants above the soil, there they uptake CO2 not O2.

  10. wont it kill beneficial bacteria & enzymes?
  11. H2O2 Works for keeping the enviroment free of bad bacteria in the rootzone for sure. However as far as giving extra oxygen the benefit is minimal at best, as the extra oxygen given off from H202 into your res. dissipates pretty quickly.

    IMO H2O2 is only needed in enviroments than have room for improvments i.e. Lowering res temps, lightproofing your res.

    I should not have even posted here, there must be 5 or 6 other threads discussing h2o2 if not many more :)

  12. My bad...i meant to say 35% not 30%....that is food grade H202. Also, you said that you recommend it only to inorganic hydro can be benneficial to soil growers as well. and I'm not 100% sure, but i think H202 is organic, all it is is water with an extra oxygen atom. so it can also be used with organics, unless you use beneficial bacteria, cuz i think it would kill that.

    I don't know if your'e saying that H202 will lower your reservoir temp or if you should use it if your res temp is too for the former, i can garuntee, that is incorrect...i used it on my last 2 grows, and it most deffinately doesn't lower the temp. as for the latter, I haven't heard that either, but who knows....
  13. Has anybody used it as a pesticide? How did it work?
  14. does medical grade 3% do anything
  15. Nah mate, not worth a damn, and neither is that 6% H2O2 you can buy from the hydro stores. It also works out cheaper if you buy food or industrial grade. By right you should use 50% grade a 1ml per litre of nutrient solution, but i can get away with the 35% grade at 1ml per litre.
    If you think of it, you will need to use 12 times as much 3% H2O2 in your solution as i do, and 17 times as much as the recommended dose. I buy a 25 litre drum of 35% hydrogen peroxide at 54 bucks (shipping not included). So you can do the figures yourself, on how much you can save (plus you are not add other junk thats in the 3% shite)
  16. thanks . you're allover the fuckin place man peace . sorry for hijacking your thread man , peace
  17. 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.

    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.
