Hanna HI98331 GROLINE SOIL/SUBSTRATE EC & TEMP TESTER AND RELATED PRODUCTS

“MY LEAVES ARE CURLING! SHOULD I FLUSH? HOW MUCH SHOULD I FLUSH”

“I’VE READ THAT MY ROOTS DON’T LIKE WARM TEMPERATURES, SHOULD I WATER MORE OFTEN TO KEEP THEM COOL UNDER THESE NEW LIGHTS?”

 

How To Measure EC with your Direct Soil EC Meter

  1. Pick your testing location.
  2. Rinse the testing probe with water, and make sure it is dry.
  3. Check the soil and ensure that the soil is fully saturated.
  4. Insert your soil conductivity tester directly into the soil, and take your measurement. 
  5. Record a few values to get an average in each pot.
  6. Learn that “happy” plants in your garden have "X" EC and temperature values.
  7. Feed or flush “non-happy” plants to match the values recorded from happy plants.
  8. Spend less time testing runoff and more time quickly testing root masses.
  9. Know what your roots see and take the guesswork out of flushing.
