In hydroponics, yeah i think it likely has a root protectant benefit but im not sure what else it really offers. I personally dont think its all that much. As far as I know, sulphur is the main nutrient responsible for producing aroma, which matches my experience pretty well. One of my stinkiest crops was flowered with very short 15 min sulphur burns nightly through the first 6 weeks of flower. Short enough that the plants are able to use up all of the sulphur by taking it in by absorbtion through the leaf, and consuming it as a nutrient. Made an enormous difference in flavor too. Only stopped because of the risk, too much can, (and did on other crops) burn the stigmas and stunt growth.Dude I love having you around. You come at it from the other direction, lay down some knowledge, and always make me think. Easy to get tunnel vision, you are like the Anti-Elon tunnel buster.
Here's what I think I know.
Fungi that grows on roots is effective in both hydro and soil to increase root surface. (there is a bit more to it than that obviously)
Bacteria that grows in soil is responsible for making nutrients in a form the plant can use. They do many other things as well.
Plants feed bacteria in a symbiotic relationship, evolved in dirt.
We do not need bacteria to ionize nutes in hydro if we use chelated synthetics.
Good bacteria colonies out-compete bad bacteria and fungus to hopefully prevent root rot.
Are you thinking all this beneficial bacteria stuff is only good for preventing root rot in hydro? All the other perceived benefits like stinkier weed is just placebo? If the only benefit is to prevent rot, H2O2 works identically?
Also having tried a few different types of micros over a few grows using Great white and RAW microbes in numerous types of media, I didn't really notice a whole lot of difference. Maybe they did something behind the scenes? I'm not sure. Nothing noticeable by any means.
