Pre-Harvest Testing

TESTING Pre-HARVEST
YES, EVEN BEFORE PLANTING

ACS is Florida’s largest DEA licensed laboratory and designated by the Florida Department of Agriculture and Consumer Services to provide sample collection and testing services.

Potency of cannabinoids

ACS tests seedlings for THC potency as well as the presence of 16 other cannabinoids including CBD, CBG and CBT.

safety & Contamination

Before planting, we test soil to be sure it’s free of harmful toxins. We also check for contamination on indoor surfaces and in the water you use throughout harvest.

Growth
Potential Analysis

We conduct tests before planting to make sure your soil is full of the nutrients it needs. We’ll identify issues right away so you can ensure a healthy harvest.  

POTENCY DETECTION

To comply with legal requirements, you must select seeds from AOSCA certified suppliers with low THC genetics. However, your harvested flower won’t always match the seed’s expected genetic profile. This can lead to accidentally growing hot hemp. 

That’s why ACS tests seedlings to estimate the THC potency; as well as for  potency of up to 16 other cannabinoids. Through vegetative potency tests, we can analyze plants early in their life cycles to help enable rapid, high quality development.

HOW ACCURATE ARE THE RESULTS?

Seedling potency tests provide the expected cannabinoid ratio, which verifies whether or not the seed’s genetics are performing as planned. The results are directionally accurate, and extraordinarily helpful for R+D purposes. However, uncontrollable environmental conditions may cause the final cannabinoid content to be slightly different from the results.

SAFETY TESTING

Soil

As hemp plants grow, they can draw in elements from the soil, which can contain heavy metals and other chemical agents. If left unchecked, these plants will grow to become contaminated hemp flower, oils or isolates. This is not a risk you want to take. You want to provide a high-quality hemp or cannabis product that is clean, safe, and delivers results. That’s why it’s so important to test your soil prior to harvest. Previously organic land could have metals in the soil. 

 

Water

Along with soil, the water you use to produce plant food and throughout harvest is your crop’s life blood. If the water is contaminated with heavy metals, pesticides, or mold for instance, your crop may also become compromised. When water is contaminated, it changes the growing conditions and can accidentally harm or kill an entire plot.

Room & Surfaces

If you are growing indoors or in a greenhouse, you want to be sure that the surfaces in the facility are 100% clean. That means testing for microbial contamination such as mold, mildew, bacteria and salmonella. At ACS, we conduct thorough swab tests of every surface to verify that your building is safe for growth.

CONTAMINANT TESTS INCLUDE

Am I required by law to test for all of the above contaminants?

Pre-harvest tests are not legally mandated however, they are vital to mitigate potentially devastating issues early in the growth cycle . At ACS, we recommend all hemp and cannabis growers consider testing their soil, water, and any surfaces they may be using to grow or process crops. 

We also have this article available for more information on when to test hemp.

Growth Potential Analysis

Plants need the right ratio of nutrients to grow properly and produce the desired results. That’s why we recommend analyzing growth-potential before harvest to ensure the plant is getting proper nutrients and is free of mineral deficiencies that can affect cannabinoid development. 

At ACS, we empower growers with the information they need to ensure healthy growth and development.

MICRONUTRIENT TESTS INCLUDE

  • pH Level
  • Conductivity
  • Micronutrients
  • Bicarbonate Level
