Diy 100% H2o2

would this work on isopropyl?

I think you guys don't smoke enough! You all seem to have retained way to many brain cells. I don't even know why one would need rocket fuel for a grow. Never mind all the chemical mad science talk in this thread.

All I know.. is I used to be a model rocket enthusiast for years, and suddenly I feel like getting back into it..

Damnit

I know the Twinkie is back, and I believe in the slush theory

What Im saying is out of one pint or 473 ml of normal off the shelf peroxide, you can obtain 14 .19 ml of 100% peroxide by placing it in the freezer and locking up the water.Then remove the pure h202 and dilute it to whichevr strenth you choose.Its a very basic concept I think its just over looked.

H2O2 =

97% water

3 % H202

Yield of 100% h202 = 14.19 ml

If you wanted 50% strenth just add 14.19 ml of water to yield 28.38 ml of 50% h2o2

@ a cost of about .99 cents

basically, you will be paying $1 for 28ml 50% H2O2, that's way way more than what it would normally cost. damn, I buy 30 Liters of 35% peroxide for like 40$. this method is like removing fat from soap and trying to resell it to soap manufacturers, just doesn't have any merit whatsoever

And to think all this time I've been using perlite to allow better drainage and a more oxygenated soil. I must be missing something here cause my brain doesn't get why you would put peroxide into your soil. I have heard of using a diluted solution of it for things like powdery mildew. Maybe I'm just way off track.

From where? I've yet to see 35% for less than ~$10 per liter and I could use a restock.

It is usually used in sterile hydroponic systems...in soil, I'm not too sure. Maybe as a one or two-time wash to get rid of bugs?

I call bull shit! the freezing point of H2O2 is -0.43 degrees Celsius. that's less then 1 degree difference from the water that the h2o2 is mixed with. So, unless your freezer is exactly 32f (which it isn't) you just get one block of ice. i tried. its not like alcohol.

Damn...I read through 3 pages of Bullshit to get to a competent answer at the very end ... thanks (I think!) P.S. we need a Cannabis "Myth Busters" crew, want the job?

The twinkies is back. At least there was some useful info here.

Personally, i say put seeds in soil, water, eat twinkies and watch them grow. But man i love to read about being stoned and building shit! You guys are great. Ive built half of the stuff ive read about on here (even tho i didnt really need the product) and only about 10% of it actually worked, but i dont care, i have entertained the shit out of myself! You guys keep smokin and designing stuff (grow rooms inside of twinkie boxes is what im working on now) and ill keep smokin and reading! Peace!

Not really something that should be treated as a "toy". I would hate to see your skin after exposure to 100% H2O2... I find 35% to be bad enough.

Hydrazine is also rarely, if ever, used in "toy bottle rockets".

They use it in commercial satellites for a reason. Unlike black powder bottle rockets.

My thoughts exactly; I was going to warn of that myself.

Well problem with 100% Peroxide is that its a mutegen at that high of a concentration and will damage the cells dna aka could cause cancer.

Im new so maybe I'm just revistitng something here.

Simply place 3% peroxide into the freezer to lock up the 97% water and now simply decant off the remaing 3 percent that will now be 100%, dilute per needs. This beats paying for the horto grade hands down.

Should also add if you really must do this it be cheaper to buy the 29-35% peroxide at a hydro store then extract it. At say Walmart you get 225Ml of peroxide for $3.99 at the LHS you pay around $10 per 1000ml for 29% (Canadian peroxide % limit for retail sales you can sell higher concentration but have to get a special free license from the gov, same license for selling Potassium Nitrate)

somewhere i read that in a side by side test with h2o2 and clorox bleach that the bleach did a better job at keeping the res sterile and pathogen free. I dont buy into the h2o2 scheme anymore ive been running clorox for a year now at a rate of 1/2 ml per gallon every 3 days same bottle i bought a year ago. my roots stay nice and white.STOP wasting your money on h2o2. shit will burn ya too!

Well the bleach will kill all bad and good microbes so yah I'd imagine it would work at small doses although plants do react to bleach. H2O2 will kill most but then it could boost other things as it breaks down to oxygen. Not sure what happens when bleach reacts with Ammonia in some of the plant food products.

Not sure either bud all i know is that ive had several succesfull runs with it. I do know that it will react to the h2o2 so if your allready running h202 you need to let it desipate out of the res before trying the bleach. it will react. growing is just a never ending science project. we all have a hypothesis. but what is the conclusion ?
