Hydrogen Peroxide?

[GpsFrontier]

I am looking into using "hydrogen peroxide" in the new hydroponic systems I am building. While looking into it I have read something about using "food grade hydrogen peroxide." I am wondering if there is a difference between a food grade hydrogen peroxide and the hydrogen peroxide that you find in the pharmacy first aid section for putting on cuts. Also, if the first aid hydrogen peroxide is something I should avoid using.

From what I've read there are different strengths and the drug store solutions are pretty weak. They are also stabilized with some other ingredients that might not help out the plants. Maybe try sourcing it from where science labs buy their chemicals from?

Actually, if it is labeled hxdrogen peroxide at 35%, it should be H2O2 and nothing else. Otherwise, or if there are any additives, - they should figure on the label. Low concentration H2O2 may use some stabilizers, but I've read studies where "stabilzed" low concentration H2O2 was used to disinfect setups .

As it is a powerful disinfectant and antiseptic, it kills every living organism but the plants, if used in the right concentration (dilution).

Though, if using hxdrogen peroxide one should be aware that all micro organisms in the systems get killed- also beneficial organisms or fungus die. As I add Trichoderma harzianum to my reservoirs, I am obviously avoiding the use of H2O2.

I just thought I would post an update in case it helps anyone. I had e-mailed General Hydroponics with the same exact question and there response was:

"Hello,
I think the only difference is the concentration. Food grade is 10 times stronger. It is also ten times more expensive.
Thanks"

I am not concerned with the concentration because I won't be using that much to go to the time and effort of finding a source for the 35% concentration. One bottle of the 3% from walmart for $1.06 will probably last 6 months. If not whats another $1.06.

The drug store stuff in a small system is perfect, the 35% stuff will burn your skin. seems like every time use the stuff i get some on me. very bad stuff at full strenght.

Try it on your hair, to see how tough it is

i think its also used in www.gofast.com jet pack. they spray it acroos some type of metal and it turns to steam and produces the equevelent of 800 hp for a couple minutes. very cool flying videos

The links not working for me.

JET P.I. - Jetpack International - Home of the Go Fast JetPack try this one. the cool part is there is no combustion so there is no pollution.

That works.

Not sure If you know but the "about us" page of the site was what the link was to. It didn't tell me anything about the fuel used, but I just back tracked to their homepage.

The video on the home page did say what they were using the 90% (very unstable giving it a short shelf life, I'm sure,) hydrogen peroxide on precious metals for the chemical reaction for the thrust. I checked out a few of the videos in the gallery section of the site. I must say I am very impressed with how much control he has, landing that softly on a dime. The only problem is he only has about 30 seconds of fuel if I understand correctly. Not sure it will ever become that useful due to the short fuel time, and the use of the precious metals making it expensive. But that's how good ideas start. Taking an idea, making it work, then refining it to be efficient.
