Why is measuring pH important for growing your plants indoors?

 

Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range.

 

From a water chemistry perspective, pH (potential Hydrogen) plays a pivotal role in making the nutrients in your solution soluble so that they can be accessed by your plants. That’s why if your growing solution becomes too acidic or too alkaline, the plants won’t be able to get access to the nutrients they need to grow. The temperature of your growing solution is equally important as having a solution that’s too hot or too cold can affect growth rate and structure.

 

To help your plants thrive, get the fundamentals right by measuring pH and temperature to ensure that these are always in the optimal range.

 

How to clean a Bluelab pH Pen

Regular care and maintenance of your Bluelab pH probes is important to ensure accurate readings. Salts and organic oils can build up on the probe blocking the sensors, so  if your pH readings seem incorrect, are fluctuating, or you have an error message on your pen, it's likely your probe needs some care and cleaning.

Check and clean your pen once a month for best results.

Steps to Clean a Bluelab pH pen

  1. For the Bluelab pH Pen, pull the cap to remove.
  2. Fill a small plastic container with clean tap water. Add a small amount of Bluelab pH Probe Cleaner or mild detergent to the water.
  3. Gently stir the probe tip in the mixture
  4. Ensure that you don't knock the pen on the side of the container as this might cause damage to the glass probe. Rinse well under fresh running water to remove all traces of detergent.
  5. If it requires removal of heavy contamination: Gently brush around the glassware with a few drops of Bluelab pH Probe Cleaner or mild detergent and a soft toothbrush. Rinse well to remove all traces of detergent.
  6. Calibration is required after every clean. 

 

Calibrating to pH 7

  1. Turn the pH pen or probe on 
  2. Press “power/hold” button.
  3. Place probe tip in fresh Bluelab pH 7.0 Calibration Solution. Wait for reading to stabilise to between pH 6.6 - pH 7.5.
  4. Long press the Cal button on the pen or meter until “CAL” is displayed. Release button. A calibration sequence will start, sequentially flashing "0" across the display. After "0000" stops flashing,  the sequence is complete, and “pH7” is displayed.
  5. Rinse pen or probe tip well in clean tap water and shake off excess. 

 

Calibrating to pH 4

  1. Place probe tip in fresh Bluelab pH 4.0 (or pH 10) calibration solution. 
  2. Wait for the reading to stabilise between 3.6 pH - 4.5 pH.
  3. Long press the Cal button until “CAL” is displayed. Release button. 
  4. A calibration sequence will start, sequentially flashing "0" across the display.
  5. After "0000" stops flashing, the sequence is complete, and “pH4” (or “pH10”) is displayed.

     
  1. Confirm calibration - A checkmark will be displayed at the bottom of the pen or meter screen to indicate a successful calibration. It will disappear after 30 days to indicate calibration is required.
