Water Quality

Many cannabis growers spend too much money and time with water treatments that do not add to the value of their crops. We can help you make good decisions about the water you use for growing. 

Testing for water quality adds to your data and supports a complete picture of your growth media. Our process here encompasses: 

  • Chemical and mineral analyses of the water sample.
  • Recommendation for adjustment/amendment of filtration or irrigation water, based on the data.

We  test water for: pH, conductivity, sodium adsorption ratio, calcium, magnesium, potassium, sodium, iron, carbonate, bicarbonate, chloride, sulfur, salt concentration and boron. We offer price breaks for three or more tests.

Following the test, we will use your data to make recommendations on aspects such as adjusting filtration, irrigation, or the treatment of your water.  

Sampling Water: How to Do It

The key to the success of a water sampling program is proper handling and preservation of samples. Sample Containers:

  • Use only clean plastic containers for holding water samples
  • No glass
  • No pesticide, surfactant, or fertilizer containers
  • Container and cap should be rinsed at least three times prior to sampling, using the water to be sampled.


  • Samples from streams should be collected from running water, well downstream from tributaries.
  • Collect from the center of the stream, where the velocity is average and chances of solids settling is minimal.
  • Samples from ponds or pits should be collected when they are in use for irrigation. Take samples at various depths.
  • Well water should be collected after the well has been pumped for a period of 1 to 2 hours.

Handling and Storage:

  1. Fill to the top of the bottle to limit air exposure.
  2. Squeeze air out of bottle before putting on lid.
  3. Seal sample bottle tightly.
  4. Ship to lab within 24 hours.
  5. If sample is to be held longer than 24 hours, keep refrigerated.
