most of those machines in front of grocery stores are 7 stage ro water the stuff i get for 25 cents a gallon tests at 0-3 ppm and 6.5-7.0 ph i buy it for coffee ,drinking,humidifier, and sometimes the plants get it, usually its just clones and seedlings, and if my tap is testing over 400ppm i dilute it by half ,im on well water and with the exception of some iron and calcium its pretty good, no chlorine or chemicals
