Growth Technology ph buffer 7 question

Discussion in 'First Time Marijuana Growers' started by vibrationalprimate, Aug 11, 2017.

  1. so I have been gifted a bottle of growth technology Ph 7 buffer for calibrating ph meters though the bottle has no directions for use. Does anyone here know if I have to dilute the solution in water (if so what measurements) or do I use the solution pure???
  2. It's solution buffered to PH 7 providing it's not stored at extremely low or high temperatures. Pour some out into a separate short glass to prevent contamination and dip your PH pen in. If it doesn't come up 7, it needs calibrating.
  3. You will also need 4.0 calibration solution for you pH meter to be accurate.
  4. shot glass is what I use so I don't have to pour more than needed
