hydrogen peroxide as fertilizer?

[gixrj18]

I agree with Ray....I used it with every feeding for about a year, and have since discontinued use with no differences. It's just an extra cost, it just turns into water anyway.

Yeah, but does it give you blond chids?

I use 50% H202 at 2ml - 4ml per 10L of nutrient solution in my hydroponic orchid setup to buffer against pathogens spreading in the water. I just started using it as of a month ago, and we'll see if it makes a difference. I have many plants growing in a shared reservoir so pathogen spread is something i've been wary about... i haven't had any problems in over a year, but better safe than sorry, and a few free oxygen particles hunting down organic cells in the water might be a bit of insurance.

Not sure if it helps the oxygen content of the water, but i never had a problem with insufficient oxygen in the water in the first place. I'm more interested in it for its bug killing properties.

Yesterday evening I read a discussion on this topic on a german forum. The question concerned the sterilization of rainwater used for orchids watering. It was recommended to use 1 ml hydrogen peroxide at 30% per 1 liter of water.
Reference Here.

Thanks Intruder, even with google translator it was an interesting read!

I wonder why someone would think that rainwater needs to be sterilized for use on plants? I also wonder why someone thinks 1 ml/l of 30% H2O2 would be effective to "sterilize" the water. Seems that would be a function of the biological load of impurities in the water (assuming there is any).

Sounds like the making of another internet myth.

I think a lot is lost in the translation...

First, that discussion was mostly about using melted snow to water, which had been sitting on the roof all winter. Someone else said they used it for water from flat roofs, where it had pooled and sat for a while. They were special cases, not just rainwater.

Second, 'sanitise' is the word i hear in relation to H202. I don't think anyone believes it completely sterilises water. But consider that a few drops of household bleach per litre of water is recommended to effectively 'sterilise' drinking water in emergency situations, and H202 is a stronger oxidiser than chlorine. So it doesn't take much.

I plan on looking at water samples under the scope to see whether h202 really does kill little swimming critters in water at different dilutions.

I grow the vast majority of my orchids, hydroponically. While some systems have the roots of the plants constantly sitting in water, they are constantly aerated also. My orchids are in various mediums, clay pellets, diatomite, sphag. moss, bark, and even coco chunks. They are on a flood and drain table, which is dry except for about 10 minutes once a day when they get "watered". Ludisia discolor love it, and are all in spike for me right now, as is a brassidium noid (2nd X,since I got it this spring), and a totally unknown (big round psuedobulb, two leaves comes out the top), will post pictures of it tomorrow if you like. Down side of this is that should you find mealies on one plant, look closely at the rest ....I will get rid of these little @#$%*! one of these days.

I don't bother with H2O2, unless my other varieties of plants get some root rot. The down side of H2O2 is that it can react negatively with some hydroponic fertilizers/additives. I'm suffering a mental block and can't remember which right now. I'll post that later when I remember, or I bother the other half about it, when he gets back.

You may not think you're growing hydroponically, but if you are adding fertilizers every time you water your plants, and they are in pretty much any medium other then soil, then you're growing hydroponically. Most container plants would not thrive otherwise, simply because without the additional fertilizers they would deplete what was available to them in the container very quickly, due to the watering regime and the plant actually using elements up.

Sorry for the lecture/long post.

Mabuhay!

This is a very interesting information. I would just like to ask if i am going to spray an orchid plant with this solution how much should i add in the water if i have a 7 liter and 3 liter spray bottles?

I just can't comprehend when it comes to ppm and other measurement terminologies...can someone translate that in to tbsp? hehehee

thank you in advance for any response.

Wouldn't KMN04 at about 2.5 ppm be a better and cheaper choice ?
