- 7. Today’s discussion… ■ What is hemp? ■ Why grow hemp? ■ Growing for purpose ■ Hempin’ ain’t easy… ■ MONEY
- 8. HEMP IN THE USA ■ Hemp Prohibition: ■ 1970 Determined not different than Marijuana ■ Farm Bill 2014 (SC got involved) ■ Farm Bill 2018
- 9. What is “Industrial” hemp? ■ ALL Cannabis sativa ■ Hemp seed oil, fiber, seed & cannabinoid production (CBD) ■ 0.3% or less inTHC
- 10. Plant Biology
- 11. Cannabis sativa ■ Dioecious- male and female flowers occurring on separate plants. Hemp grown for CBD. ■ Monecious- male and female flowers occurring on the same plant. Hemp grown for seed/fiber.
- 12. Cannabis sativa (CBD production) ■ Female flower ■ Photoperiod: Short-day plant ■ Can be grown from seed or vegetative cutting
- 13. How do we induce flowering? Long days: 18+ hours of light Short days: Less than 12 hours of light Grown for 3 weeks Grown 8-12 weeks VEG Flower
- 15. Planting date July 20th June 13th
- 16. “Auto-Flower” “Day-Neutral” PROS ■ More harvests/year CONS ■ Expensive seed ■ Low CBD potency ■ Low availability ■ Smaller plants
- 17. Secondary metabolites ■ Cannabinoids: Resinous oils produced in trichomes of flowers. – THC andTHCA-Tetrahydrocannabinol- psychoactive – CBD- Cannabidiol – Over 100 cannabinoids **Mainly determined by cultivar selection** Trichome
- 18. Secondary metabolites ■ Terpenes: Compounds that attribute to smell – Ex. Limonene, Linalool ■ Extremely volatile! – Drying method important Trichome
- 19. Growing for purpose ■ Where? ■ For what purpose ~ what is your end product?
- 20. HOWWILLYOU GROW?
- 21. Process flow considerations… Finished Product • Flower • Concentrate ExtractionType • Solvent • Solvent-less • None Post-Harvest Conditions • Slow/low • Fast/high • None Cultivation Practices -location -cultivar selection
- 23. Solvent Extraction Methods ■ Solvent: – Hydrocarbon – CO2 – Ethanol
- 26. Post-Harvest
- 27. Water Activity Meter (Aw) Microorganisms have a limiting water activity level below which they will not grow.Water activity (AW), not moisture content, determines the lower limit of “available” water for microbial growth. Since bacteria, yeast, and molds require a certain amount of “available” water to support growth, harvesting at the proper AW is crucial. Scale 0-1 *Rotronic*
- 29. Water Activity during drying 0.8 represents the value in which Botrytis cannot continue to grow Days 1 14 AW 0 1 12 0.8 0.6 Consumer Preference Area in which enzymatic activity can continue (1-0.75) 2
- 30. Curing/Smokability Cultivator selection Cultivation Practices Post-Harvest Practices Moisture Content Speed of Drying Curing
- 31. Russet Mite ■ TINY ■ 20 to 170 µm long and up to 65 µm wide PROBLEMS
- 34. Cannabis products ■ Cannabis fertilizer 25x more expensive
