Can I re-use the waste water?

[Rickcin]

I usually toss the runoff water when watering my girls and it just dawned on me that perhaps I could mix this with the already nutrient mixed water to water the girls the next day instead of tossing it? Thanks

Bad plan. Asking for pathonogens.

I don't think it would be cost effective. You would have to sterilize it, then test it to see what it's nutrient levels were.

You can use it outside on your grass pretty easily lol

If your wanting no waste go aquaponics and pick your biproduct.

I would only reuse wastewater from rockwool and even then it has to be filtered and UV treated before being fed back to the plants. Doable, I actually do it myself, but again I only do it with wool and UV.

So im curious to as if someone has ever put a uv light in their res, under the root structure lol. Wouldnt it stop root rot that light would normally cause? Retention time right? lol. . im assuming someone has done this. Just curious as to how it would work on sterile systems with chillers. I just find it wild how one spectrum can cause fungi growth, and one can eliminate it? Am I just confused?

Visible light is just radiation. UV kills living things. Oxygen gives life as O2. And kills as ozone. UV lights are encased and used to to sterilize aquarium water without shining on the fish. In hydroponic use its called a UV clarifier or something.

What Every Indoor Farmer Needs To Know About UV Clarifiers

UV clarifiers are good for controlling water biology in both hydroponic and aquaponic systems. See how a UV clarifier works in our indoor hydroponic system.

Why would you? It's really Wastewater.

Don't waste it. Use it on your outdoor veggies or other plants. If nothing else, add it to a garden sprayer and fert your lawn.
