When To Test
Maximize Yield & Quality.
To avoid costly issues, growers should consider plant health testing at key stages.
Early In The Season
Performing plant tissue and soil tests helps establish baselines for nutrient needs
Mid-Cycle
Run-off and nutrient water analysis are useful tools to ensure your dosing is accurate and prevent nutrient deficiencies.
If Disease Is Suspected
Targeted tests like Pythium, Fusarium, or Hop Latent Viroid can confirm infection early.
Before Harvest
Heavy metal testing ensures that crop material meets safety and compliance standards.
If you are thinking about plant health testing for your grow, consider the following. You may need testing if:
“The plants look healthy, but yields aren’t where we want them.”
“We're seeing inconsistent results, even with the same genetics.”
“Our plants seem to stall out in late flower.”
“We’ve been tweaking the fertigation recipe, but it’s still not dialed.”
“We had a great run last cycle, but this one is way off.”
“We’re noticing salt buildup or clogging in the lines.”
“We’re getting weird pH swings in the root zone.”
“The EC of our runoff is way higher than what we’re feeding.”
“We recently switched water sources.”
“We’re having trouble keeping plants consistent across zones.”
Testing Catalog
Labs Tests Details
We will ship the appropriate sample holder and accompanying instructions, along with a return label (if requested) for sending it back to our facility. Test results will be available within 2 to 3 business days, or 1 to 2 weeks, depending on the test, after which one of our Cultivation Advisors will contact you to discuss the next steps.
Plant Tissue Analysis
In the Field: Starting point for diagnostic testing. Can determine nutrient related issues.
Soil Analysis
In the Field: Beginning of Season test for outdoor growers to help them determine fertilization strategy.
Run Off Testing
In the Field: Check to see what Nutrients are present in run-off to make adjustments on fertilization program.
Pythium ssp. Testing
Pythium ssp. is a water mold fungus that causes a variety of plant diseases, including damping-off, root rot, and cottony blight.
Water Analysis
In the Field: A sample of Tap Water and RO Water can help us determine if RO System is functioning properly.
Nutrient Water Analysis
In the Field: Check to see if nutrient batches are properly mixed.
Heavy Metal Testing
In the Field: Check to see if there are unsafe levels of heavy metals that will not pass compliancy testing.
In the Field: Grow media testing to ensure there are not unsafe levels of heavy metals present that plants can absorb.
Hop Latent Viroid (HLvd)
HLVd is a plant viroid that causes growth deficiencies and stunting/dudding of the plant.
Fertilizer Analysis
In the Field: Checking to ensure fertilizer mix is within acceptable range.

Plant Health Lab Tests
Our Lab reports test results within 2-3 business days of the sample arriving at our lab.
Test Results
Consultation call with a Cultivation Advisor.
After you receive your results, expect a consultation call with a Cultivation Advisor who will walk you through the findings in detail. They will help explain what the results mean for the specific stage of the grow cycle, identify any nutrient imbalances, pathogen risks, or environmental concerns. The goal of the call is to turn lab insights into actionable next steps tailored to the grower’s unique operation.
