Parts per million and reservoir question

  1. easier way would be to get a reverse osmosis filter set up.. zero ppm and 7ph after its filtered! (or close enough to that)

    but i've been growing with that kinda water my whole grow, if your on city water let it sit for a few hours b4 you use it ( to let the chlorine evaporate) other than that your fine :)
  2. nice tits. thanks for the advice.
