  1. how can i lower the ph of the water cause where i live theres no hydro store and the one that i order from takes for ever to deliver
  2. If you are growing in soil you can use vinegar to lower the PH. If growing in hydro do not use vinegar.
  3. Go to pet store and use the the stuff they sell there works fine.
    Thanks Dale
