Using Mini Canna Lab for R&D Testing

Mini Canna Lab was originally developed for the homegrower and home medicine maker.  However, after spending time with those in the industry, I have a set of specific guidelines for using this home test kit to accurately analyze cannabis flower or product in order to compare it to lab results. Mini Canna Lab will NOT measure down to the tenth of a percent and is not suggested for verifying Hemp legality.  However, there is still value for those in the hemp industry, read on. 

First a little background on testing in general:

Labs using HPLC will test flower in its raw state.  Giving reading of all of the acid profiles (example THCA, CBDA, CBGA, etc) and then multiply these numbers by .877 (specific gravity of a carboxyl group) to get the POTENTIAL activated cannabinoids.  

THCA x .877 = THC

Flower in its raw state also contains moisture that will add to the weight of the sample (samples are based on weight of the product) and skew results at times.  Many labs are doing what they call "moisture content" readings by removing the moisture or taking it into account in a mathematical way. 

Seeds also add to the weight of the sample.  Because of the small sample size of Mini Canna Lab, if there is a seed in the Mini Canna Lab sample it will skew the results.  Does your lab samples contain seeds? 

Sample size is the biggest factor in lab consistency.  A small sample size is great for measuring tight flowers or buds.  Results will be high in all cannabinoids.  If the sample size contains leaves, stems, or flower with less trichomes, the cannabinoids will be low.  Know what results you want and calculate accordingly.  If the state is choosing the samples, understand what they are collecting and how it affects your results. 

In many states, THC is now broken down into both delta8 THC and delta9 THC or total THC.  So it is important to understand what your lab is testing.  

Comparing to Mini Canna Lab

1. Use the same lab every time you test.

2.  Understand how the lab tests.  See above.

3. When using Mini Canna Lab, decarb flower samples the same way every time.  Pick a time and temperature in the same oven or toaster oven in the same muffin tin or whatever procedure you like, do it the same every single time.  The most accurate cannabinoids profile is from a fully decarbed sample. If you are unsure if your sample is decarbed or want to know more about decarboxylation please click here.

4 . Compare a few chosen lab results with Mini Canna Lab and dial in the potency chart.  The chart is typically within 1% of the lab but you need to compare a few tests to make sure you are using the chart properly for your lab comparisons.  

5.  Make sure to spot the plates on the dots and remove them from the developing chamber at the line.  Removing too soon or too late will slightly skew the results.   

6.  Use the overall cannabinoid profile to assess your product.  Processors can affect the overall profile significantly.  Learn to differentiate your product by marketing different cannabinoids.  For example, here is a distillate that has a significantly high percentage of CBG. Here are a few samples that I decarbed on the plate.  This high temp brought out CBDV and CBDN which were not present in the same sample that was decarbed in the oven at 240 for 40.
