Indoor Next up - Barney's Watermelon Zkittles

Hey @420autoflower , I have a 335 ppm from the well. Anything I can do to lower it? What is a good number to be at or below?


Thanks!!!
Hey Darren!
I don’t think there’s anything you can do to lower the ppm except to run your well water through a simple R/O device.
I’m curious to see what your ppm is after you add your normal amount of nutrients in.

I use a countertop R/O unit that I can move around the house and hook up to any faucet or even a hose bib. The water coming out is right around 15 ppm and that gives me a lot to work with and no risk of over fertilization.
