I'm a full hydro, such as DWC, ignorant coco user and have a question: What is sterile hydroponics? Seems would be impossible to attain? Why ever want sterility? Are there actually downsides to adding beneficial microbes in DWC/full hydro, or ever?
Does this refer to real sterility, or to simply not adding nutrients or supplements with live microbes? Or does this refer to rigorously only feeding inorganic salts, nothing organic? How does a grower keep down microbial growth in nutrient-rich water, with lots of dissolved O2/air, with the plant roots shedding organics, etc.? Do you add anti-microbial agents, whether 'natural' or not, or otherwise work to limit microbial growth? For ex., add hydrogen peroxide to the water? Does sterile hydro include sterilizing the media at the start, as one would do for growing microbes (cell culture), making beer, etc.; or even running constant loop water sterilization, such as using UV or filtration"? Is the air supply filtered to remove microbes, as is done with 'clean rooms'?
