Hydrogen peroxide is good for a lot of things, including killing that pesky algea that likes to grow on your medium. But you have to keep in mind that it will kill everything bacteria wise, including the good ones. Not a good thing if you are using organic nutes.
ill have to agree with what unique said ^^^^^^^

also, i THINK I READ you want to add h2o2 at a rate of 3% your total res amount.... so if you had 100 gallons, you want 2 gallons to be 50% hydrogen peroxide...

also, i heard the h2o2 dissipates relatively quick and wont stay in your res for more than a day or so..?????

i should have bookmarked that page with all the other h2o2 info....

later:peace:

I your quote is correct it would be 1.5 gallon @ 50%
your right. im kinda drunk right now. its friday night and i got a little shitty... my maths not so good after 6 drinks:mrgreen:, but 1.5 gals would equal 3% out of 100 gals. ill have to find that link


:peace:

you can use hydroge peroxide but you need to dilute it 100 / 1ml of water and it needs to 1% vol
ie if you buy a bottle and it 20 % you need to add only 1ml per every 2000ml
if you buy a bottle and it 10% you need to add only 1ml per every 1000ml


hope this helps its usually only added to kill incests and bugs

tablespoon per gal of 3 percent h2o2 best for hydro it kills beneficial organisns in soil grows. and from experience it does not kill fungus gnat larvae unless you use enough to hurt your plant. h202 is basically water with extra oxygen molecule or put another way it is acts like ozone in liquid form something we use in the aquarium industry. in concentrated form it will burn right thru skin. i not useing it on this soil grow because i am using tarantula and piranha. i do use a dilute mix to help germ seeds it keeps them free of bacteria/fungus and adds available oxygen it is very unstable and has to be changed frequently as it breaks down when exposed to organic material. i have heard i will de-chlorinate tap water that contains chlorine(i dont know if it works on chloramine) i have not tested this though. it is best to get 'food grade' h2o2 because the 3% at the pharmacy has additives and stabilizers i never noticed problems with the cheap stuff but who knows.:peace:

Another person from the aquatics trade, eh? You in L.A. perchance?

I wonder, then, since there's talk here of fungus among us, if methylene blue is ever used for fungus control as it is with fish eggs (it's also used in some types of surgeries to stain bad tissue that needs to be removed).

I tried using it on my hydro grow a couple of years ago. The plants freaked out big time! I posted the pics at that time on OG. The plants were a few weeks old at the time. The general concesus was the plants were too young and most felt the h202 wasn't really needed in hydro. I haven't tried it since though. Don't want to risk it. I was growing bagseed then and it was my virgin grow. I often come across post bringing up the question again. It appears many people find it helpfull. I would suggest if your not that experienced a grower you might want to forget it. Just my 2 cents!

also, if you dont have algae or bug problems than you dont need to use h202. if your DO in the res is up high enough you usually dont need to use h2o2 because you should NOT have algae problems.

yeah i worked at a aquarium spot on ventura blvd for 6 years. makes learning this much easier if you can keep a nice reef tank you can definetely handle cannabis. i miss having my 80gal salt fish only set-up. but cant afford now so it gathers dust in the garage.:peace:

I sold off most all of my aquarium stuff many, many moons ago. I can do reef, planted, ponds, whatever the boss threw at me I've worked with.

I saw a couple of incorrect posts and stopped reading so sorry if this is a repeat

Hydrogen peroxide, H2O2 is similar to a water molecule with an additional oxygen. It is a stable structure but not very strong - the oxygen will leave the remaining, stable H20 to bond to other compounds. It so happens most of the compounds are bad and incidentally the oxygen disrupts the structure, neutralizing it. Im not sure why some of the oxygen ends up by itself as a byproduct, all I know is that it does and that roots need oxygen to live, grow, absorb nutrients and water etc.. function..

(Ive heard the majority of experienced growers using 1-4t/gal)

hydrogen peroxide is different from hygrozyme. hygrozyme is an enzyme that breaks down dead root matter, which is a good thing. hydrogen peroxide is water with and extra hydrogen molecule. i have never used it, but i think it breaks down and gives the roots more oxygen (research yourself, don't take my word. i have never used it), and it kills some bad stuff. hygrozyme is NOT hydrogen peroxide, or H2O2.
I didn't read all the thread, but you're right.. I'm using it "occasionally" this year for 1st time because my plants were wet for about 60 days straight due to shitty weather..It seems to have helped, but that being said,more experimentation on my part is still needed.....

Tried it once on young plants and learned you should only add it to older plants. Many on here and elsewhere swear by the stuff for problem grows. I didn't see any benefit but my application was wrong.

Hey, I have algae on the tops of all the rockwool cubes in my aero system. I covered the net cups with white plastic, but i have also been thinking about adding hydrogen peroxide. The plants are really young, do you think this is a bad idea?

im am trying to figure out the same thing -- now i understand what it's for, but how much do you use? do you add a little bit too it or use it instead of water
*btw i'm a first time grower*

I grow in rockwool also. The algae growth is normal and you did the right thing by covering them with white plastic. It does not harm anything but can become a huge mess. Like I said before in a post young plants cannot tolerate the harshness of hydrogen peroxide.

30ml/gal (why the metric-standard measure, I don't know) when using the 3% solution is what I remember seeing posted for plants that need a boost.
