my tap water is 330ppm - after refrigerator carbon filter , it is 300. it limits the amount of nutes you can add- i use rainwater. Don’t you get a Mauka shower everyday? Mahalo bra!
The filtered water I use comes to 210 ppm and I actually do get a lot of rain where I live which is why I don’t really want to grow outdoors. What are the advantages of rain water? I live way up in the mauka haha
