.snot a gimmick it chemistry man...you don't need a catalyst unless you are making it then its platinum electrodes all tha way. The chemistry is simple...H2o2 is a reactive oxygen species and a very powerful oxidizer this means it wants to steal electrons from most of what it touches the electrons are e- in the following equation 2H2O2 + 2e- => 2H2O + O2 so it breaks down into water and pure oxygen (cf 21%atmospheric) this increses the oxygen in tha soil an kills a few microbes...use very dilute....don't chuck...and icm your plants look ok they have plenty of N and look nuted not def.
Please, don't give me it's not a gimmick it's chemistry and then spout me an advertising leaflet.
What you've got to ask yourself is......
What concentration is the HP that I'm getting? (How much needed for how much oxygen)
What is the concentration of HP in my feed water after I've mixed up? (now it's watered down to fuck again however much is used)
At what rate does that concentration of HP decompose naturally without a catalyst?
What kind of soil/mediem levels of oxygen does this rate give and how long before dispersion? (Only ever until you water unless hydro but then it's pointless cos of the airstone)
What are the maximum levels of oxygen my roots can utilise at any one time?
What's the theoretical bang per buck I'll get from using it based on levels of oxygen vs level of utilisation?
In the amounts we're talking in the products available fuck all.
Coco + airpot's and your plants are all ready better than nature, if you want more oxygen to your roots than that then go hydro because that little bottle isn't bringing anything to the table in the real world given that context.
