Hmm, So I guess I should not be using it with Bud XL and Multi- Zyme huh? If it kills bacteria, will it kill my good enzymes and what not?
heres the thing.
h2o2 should be used as a last resort. it ultimately does not kill pythium or the majors....it only keeps it at bay. it basically oxidize whatever so its made available to the plant.....
furthermore, the use of h2o2 can kill off beneficial microbes and such in your roots whether fully chemical or not. Roots still are alive and kicking and have that 'organic' life to them regardless if you only use chem nutes....
moreover...h2o2 is nothing more than a chemical airstone with some added benefits.
h2o2 become very popular on the growing scene when hydroponics emerged. At the time, res chillers were barely heard of, let alone using them for growing....
as more and more knowledge came about keeping your res cool and obtaining max DO (dissolved oxygen) by having the nute solution circulating and 'chilled' you can obtain 14ppms of DO...things started to become apparent.
The reason why h2o2 is viewed as more economical in certain setups is because only a few systems are picky picky when it comes to certain res temps i.e. dwc, aero, nft shit like that....
of course any body of water can turn picky. picky in the sense of....if you dont maintain it....nasty pathogens WILL grow (trust me on this, i KNOW)
ebb n flow reservoirs are held to the same standard as any other body of water and its pickiness...however the roots are not dangling in the hot temps and they most of the time sit in pots of medium when in ebb and flow setups this is why you can get away with it.... furthermore....supplementing with h2o2 (35% as the 3-5% sold in stores are just unstable) can keep most ickies at bay by oxidizes nasties.
with all that said....this is why some growers chose not to use h2o2 cuz it can (keyword here, CAN) harm root life, and moreover will limit your options for nutes, additives, bloom boosters, etc etc
load your res up with goodies and you wont have to worry about nasties coming in. there is no way a bunch of goodies (beneficial) will let nasties take over. Its like a war of who has the most numbers...who is 'deeper', per se
but forget goodies. keep your res light tight, circulated & moving water, and last but not least....keep it cool and you wont have shit to worry about
