Water/Fertilizer

Analysis

Our Water and Fertilizer testing allows you to see what your current nutrient levels are, whether that’s in your source water, fertilizer solution, or runoff.

 

We will test for: pH, Soluble Salts, Total Alkalinity, Total Nitrogen, Nitrate Nitrogen, Ammonium Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Iron, Manganese, Copper, Boron, Zinc, Molybdenum, Aluminum, Sodium, and Chlorides. Fluorides are available at request.

Water and Fertilizer analysis starts at $44 per sample.

Media Analysis

Our Media testing gives you insight to how your water and nutrient solution are meshing with your grow media. This way you can see what’s getting held up in the media, and what’s running right through it. Note this test is not meant for field soil.

 

We will test for: pH, Soluble Salts, Nitrate Nitrogen, Ammonium Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Iron, Manganese, Copper, Boron, Zinc, Molybdenum, Aluminum, Sodium, and Chlorides.

Media Analysis -

Physical

We offer three separate physical media testing services: Porometer, Moisture, and Sieve analysis.

Porometer - The porometer test standards were developed by North Carolina State University and are done in triplicate with results given as an average. This process takes longer than our other testing processes - our laboratory can only run these tests Monday - Wednesday, once the tests are run the typical turnaround time is 3 business days.  A porometer test includes the following: Total Porosity, Container Capacity, Air Space, Bulk Density, Moist Bulk Density, % Moisture, and Initial % Moisture.

Porometer testing starts at $80 per sample.

Moisture - Determined by loss on drying and expressed in percent. Typical turnaround time is 3 business days.

Moisture testing starts at $55 per sample.

Sieve - Sample is physically separated/sorted to determine various sizes of particles contained in the mix. Results are expressed as percentages of mix retained per specified sieve series. Please contact us at 1-866-522-5752 prior to submitting samples to let us know what screen sizes you require. Typical turnaround time is 3 business days.

Media Sieve- $55 per sample

Dry Fertilizer Sieve- $62 per sample

Sieve by pan- $18 per sample

Tissue Analysis

Our Tissue testing offers you insight to the hidden world of what’s actually going on in your plants. Curious if you’re seeing a deficiency or toxicity? Our analysis helps clear things up. This is the best way to know if your plant nutrition regiment is keeping your plants supplied with the optimum level of nutrients.

 

We will test your plant tissue for: Total Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Iron, Manganese, Copper, Boron, Zinc, Molybdenum, Aluminum, and Sodium.  

 

Tissue analysis starts at $40 per sample.
