Are  the chemicals mentioned for PH balancing harmful to my health if I'm smoking the buds?  Nitric Acid is added to pool water and you won't see me drinking any of that.  Is it safer, but more bitter to use vinegar to lower the PH in my solution?  Won't that affect the dank taste?  Is potassium hydroxide found around the house or should I just order it?

  " Nitric, phosphoric or citric acids (even vinegar) can be used to lower pH, while potassium hydroxide can be used to raise pH."
