Hydrogen peroxide and clones?

    I took some clones that ended up molding so sadly, they got tossed. The mom has recovered and I'm about to try again except with peat pucks instead of rock wool. I'm about to put my pucks in water for them to swell up. If I add some hydrogen peroxide to the water that the pucks are absorbing, to try and prevent mold(as well as taking other precautions like more air.) will it hurt the plant?

    i dont think peroxide would hurt the plant but only use a couple of drops. i clone with peat pellets also but i have not used peroxide n some did get moldy.. i think it helps oxygen get to the roots better also..

    Do not put it on the peat pellets what you want to do is add it to the water in the bottom of your tray/resevoir, mix 1oz of 3% h202 with one gallon of water and DO NOT water with it or spray it on them, it kills things

    check out this article :http://www.cannabisculture.com/v2/articles/2807.html

    One part of 3% hydrogen peroxide can be combined with two parts water, or one part 10% solution is combined with nine parts water, to make a 1% solution. This solution should be used for cuttings for the first week. Nutrient and amendments can be added to this mix. It can also be used in the sprayer if you mist the plants. It is a sterilizing agent, so your cuttings are much less likely to suffer infection.

    Now try and tell me hydrogen peroxide kills plants

    calm down bro, if you found an article sayin somethin different then try it n let us kno how it works. tis is mostly an opinion kinda thing. the more you HEAR, the more you TRY, the more you LEARN. n yeh it helps oxygen get to roots so they will grow better, and his ratio is good, ive been usin bout a tbsp to a 2 liter to clear up root rot. works wonders...

    dont think he was talkn bout killin the plant tho... not sure but somethin to do wit bacteria tat you actually DO want to be there

    Hydrogen peroxide (H2O2) is known as a common disinfectant; however, the Environmental Protection Agency (EPA) has also approved the use of hydrogen peroxide as an ingredient in pesticides. The EPA has deemed hydrogen peroxide safe for use on non-food and food crops, both before and after harvest, because it is an effective algicide and fungicide at low concentrations. It also breaks down quickly and safely in the environment, into water (H2O) and molecular oxygen (O2), as shown in Equation 1.

    Equation 1:

    2 molecules of hydrogen peroxide → 2 molecules of water + 1 molecule of oxygen
    2 H2O2 → 2 H2O + O2

    Ways to use peroxide in the garden

    General fertilizer, either in plant water or sprayed on foliage. This page has much more detail about how to mix and apply peroxide in the garden.
    For sick plants. Spray on the leaves and add to water.
    Hydroponic gardening. Hydroponic gardeners often use peroxide to feed plants, by adding it to the watering system.
    Spray on tree cuts, to prevent infection.
    As a spray in the greenhouse, to control mold and mildew.
    Sprouting seeds before planting. Added to the water that seeds soak in, the seeds will sprout faster and grow stronger.
    Rooting cuttings. Added to the water, if you’ve put the cuttings directly into water. Or, if you’ve put the cuttings into soil or medium, use peroxide in the water you’re using to water the cuttings with.
    Mold or fungus on plants or in the soil. Hydrogen peroxide will help to control mold on plants or in the soil. If you’ve got mold on the plant, spraying the leaves is probably best… This page has the story of my lemon tree with black mold on the leaves.
    Weed killer. I’ve never used it this way, and I’m not sure I would want to… but I’ve read that 10% hydrogen peroxide will kill weeds. Personally, I would rather pull the weeds up. If you do decide to try this, I certainly would NOT use 10% peroxide close to other plants… and I would come back later and add a LOT of water after the unwanted plants ("weeds") have died. This is very very very concentrated……

    do i use it: yes. try pouring it in the base container 3 to 9 dropsfor misting....or heavier, but read first-- which is why i speak last. science is AWESOME garrrrrrroowwwwwl.

    I used to use it without any issues. not for clones but for an additive when watering between fertilization to add oxygen for the roots. didn't kill anything...but i was not really precise with it and didnt do side by side comparisons either. I did have killer buds

    From my experience, and I use the exact methods you are proposing, Hydrogen Peroxide does effect rooting. When used in too high of a concentration it appears to slow the process, and often lower your success rate. However so does mold, so maintaining a balance is key. When I first started growing I used the EXACT recipe bmarley posted. This concentration seemed to be a bit too high and slowed the process a bit, I now use about 3/4's of what is suggested in that article with great success.

    Like I said I have no evidence aside from experience that it slows root growth. Just something to consider if you have the same experience.
