PH and TDS Meter/Advice Questions

Discussion in 'Growing Marijuana Indoors' started by tony clifton, Aug 22, 2007.

  1. Is there any decent combo PH/TDS meters?

    Are meters generally divided into soil vs. water? It would be nice to find one that I can use when I graduate to hydro college.

    Any particular recommendations for these? Looking for decent quality, but not EPA work.

    Would everyone generally agree that 6.3 PH for soil is the way to go?

    Read that lime/lemon juice work well for PH down. Any backup on this? What about PH up? Have not seen these products in town Lowe's or at the Wally World (and as little hydro shop buying as possible is hoped for).

    Thanks in advance,
  2. Come of folks, I now some of you know the answers and have some favorite meters or recs.
    Greatly appreciated,
