This curated kit will help you identify the physical and aromatic properties of hemp, so that you can train your eyes, nose, and trigeminal nerve for interpening marijuana.  The attached Interpening TAG™ Report will identify the physical and aromatic characteristics of each hemp flower and explain how those features would be a representation of marijuana within the broad to narrow leaf spectrum.

Trichome Institute curated this hemp flower interpening kit to guide interpening students through their education with hemp flower varieties representing the broad to narrow leaf marijuana spectrum. Additionally, this kit provides everyone with high quality smokable hemp mindfully selected with our partner, Project Hemp Flower.

The kit contains three eighths (3/8ths oz) of hemp separated into three categories: Broad Leaf Hemp, Medium Leaf Hemp, and Narrow Leaf Hemp.  

Each variety includes a full panel lab analysis by Project Hemp Flower. The flower is tested for heavy metals, mold, pesticides, and other toxins; and the lab test also includes the cannabinoids and some varieties include the terpene profile as well. Trichome Institute then evaluates the flower and issues it a detailed quality assurance TAG™ report for each variety.

The TAG™ process includes information about the health, ripeness, and density of the trichomes, identifies any visible mold, insects, or faulty characteristics that generally escape traditional lab testing. All hemp selected for the training kit must pass the stringent TAG™ standards.  At the end of the report you’ll also find information on how the hemp flower aids as a guide for categorizing the physical characteristics and trigeminal nerve stimulation.

How do I get the most out of my hemp training kit?

Answers to Your Hemp Flower Questions

What is difference between hemp and marijuana?

Based off of the 2018 Farm Bill and USDA regulations, the difference between hemp and marijuana is the amount of activated D9 THC. Hemp flower must have no more than 0.3% active Delta-9 THC. Otherwise, it considered marijuana. 

What comes in the hemp flower kit?
  • Three eighths of hemp flower (3/8ths oz.)
  • Certificate of Analysis for each variety
  • Notice to law enforcement explaining the samples are federally legal hemp
  • Getting Started Instruction Card with access to TAG™ Interpening reports
Why does my lab test show more than 0.3% THC?

Total THC includes THCA + THC. Some lab tests will have a total THC percentage over 0.3%. As long as the lab test shows no more than 0.3% D-9 THC, the hemp is federally legal. THC is the intoxicating form of the non-intoxicating THCA. 

Is it legal to buy hemp flower?

Yes, hemp (cannabis containing up to 0.3% D-9 THC) is federally legal. However, be sure to check with your individual state hemp laws and regulations, as they may vary. 

Can hemp flower make me high?

Many marijuana users do not get high off of hemp due to their tolerance. However, those who have low tolerances may experience mild intoxicating effects from hemp, which is primarily due to the terpenes in the flower- not the THC.
