How to do a slurry test on plants.

Gardeners often wonder how to do a slurry test for plant soil. There are probes and meters made for making these reading of ph or ppm a very simple. We prefer to do a slurry test to dial in the ph to 6.4 for optimum nutrient delivery. Its unbelievable to see plants to cannabis grown with this technique of perfection. Below you will find 2 ways you can do this with our choice of Bluelab meters or comparable.

(NOTE! The meters below are for demonstration only, When choosing a meter be sure you get a Bluelab combo meter which will read both ph and ppm. Then you could buy a Bluelab leap probe and replace the standard probe (backup) on factory unit for best option. Or get one Bluelab multimedia meter and a handheld ppm bluelab meter.

Technique 1

Slurry testing with a Bluelab Standard Probe. 

  1. Get a jar or cup
  2. Place Bluelab standard probe inside jar or cup. (see below picture)How to do a slurry test on plants
  3. Fill 25-40% with soil from potted plant soil or field
  4. Fill slowly with Purified or ro water till reading appears.
  5. Refer to YOUR SLURRY pH in the Gold line1 left to right
  6. Now line 2  in dark blue is what you will be feeding or watering to get to 6.4 ph. Just take Gold line (YOUR SLURRY pH) and simply refer to the numbers directly below in Blue line then (Feed or Water) in at to get to 6.4
  7. Done. Now take ppm the same, happy growing.

Technique 2 (Best Choice)

Slurry testing with a Bluelab Leap Probe.
