When we say sterile, its not the litteral meaning. A 'sterile res' is the opposite of using beneficial bacteria to prevent pythium. Tap water can range from .05 ppm to 5 ppm so the 2-3ppm most people run at is not going to harm the plants.

have you grown a plant in hydro using pool shock before?
chlorine is a nutrient for cannabis. some nutes contain it.
If that were true we'd sterilize our OR instruments with it. It isn't. It creates an aseptic environment.I think if you want to keep a sterile rez the best way to do it would be using an RO filter and adding an inline UV BEFORE the water gets into the rez.
This way the chlorines have been removed along with other things and pathogens have been killed off with UV. This way the water in your rez is "sterile" and when you add nutrients no additives are messing with the compounds.
Stealth-RO™ or micRO-75™ UV Sterilizer Kit—.5 GPM
Ultraviolet Sterilizer add on kit provides 100% protection against bacteria, viruses, cysts and pathogens in the product water. Great for well or surface water sources. Ensures the safest water. Includes UV unit with ¼" quick connect (QC) fittings, clips and transformer.
you would need to run res water constantly thru a uv filter. once roots contact the water, your "sterility" is gone.
How so? If there are no pathogens present in the water than for them to be present later on they would have to get introduced somewhere.
some pathogens laugh at uv light
Damn didn't even know that was possible
No matter how sterile the water is at first, bacteria will get to it, by contact with roots, by your airstones, by contact with the atmosphere. by contact with the container walls which have little pores where bacteria grows
from your media, from your room, from your roots, from what you just tracked in on the bottom of your shoes, from that sneeze as you left your room, etc.
Yup and worse the roots don't care for UV exposure and it's at the point of exposure you get the disinfectant actions. That's why Chlorine is such a good thing.
Just coming in contact with air. Pathogens are always present everywhere. Airstones are probably the worst. They pump air into the res and they have pores for bacteria to hide.
Have you noticed any impact on your plant's growth, etc.?
You would UV the water before adding the nutrients than when the nutes are added they are than given to the roots.
It's never sterile. Even the human biome is not sterile. Think in terms of asepsis. I would not use H2O2 because it's too fugitive. Chlorine gives the best bang for the buck if you're in hydro. If you're in soil you are working to cultivate your microbial herd which will assist with pathogen suppression and plant nutrition.
From the chlorine? Nothing detrimental or I would stop using it immediately. Beneficial? It's hard to say, but the fact that I see healthy bright white fuzzy roots and green leaves that pray, tells me it's not doing anything wrong.
So, what would you do in a SIP, hempy bucket, or Octopot where there is soil or coco, than roots below that are suspended in water?
