Hey papa, awesome grow journal! Hope to start my own soon. Regarding your idea of using electrolysis for added DO, interesting idea but some things I humbly suggest considering: in swimming pools this technology is used to disinfect the water because along with H2 and O2, reactive oxygen species are created: H2O2 (peroxide) O3 (ozone) and OH- (hydroxyl radicals). Also, electrolysis will break down salts (in salt pools its breaking sodium chloride down into active chlorine). Aside from all this possibly sterilising your bennies and breaking down your nutes, it definitely will cause a change in pH (one last pool example: salt pools tend to shoot well past 9 if not buffered as the chlorine coming out the generator is 13!) Sorry for posting here,new to forums and can't find a PM function?
