  1. Does anyone know if these ph testing stips work or not?

  2. I'm sure they work (those the kind that you stick in soil?) ...I've never used them cuz i've always done hydro. When you can, you should get a digital ph meter and TDS meter (about $20 apeice on ebay). I'm assuming your doing a soil grow??? just test the ph and ppm of the nutrients before watering plants. to be more precise you can also test the runoff.
     
  3. yo foreal.
     
  4. yeah they work, but they're a pain in the ass to use compared to a digital meter.
