Cannabis Crop Management

Understanding CBD Crops

History of Cannabis Cultivation

CBD (cannabidiol) has a rich history spanning thousands of years. Ancient civilizations in China, Egypt, and Europe cultivated hemp, which is the primary source of CBD.

Understanding this historical context helps farmers appreciate the significance of CBD crops and their cultural relevance.

Understanding Cannabis Crops

Types of cannabis Crops

Industrial Hemp (Cannabis sativa L.):

  • Grown primarily for its fiber, seeds, and CBD content.

  • Contains low levels of THC (tetrahydrocannabinol), the psychoactive compound.

Cannabis (Cannabis indica, Cannabis sativa, Cannabis ruderalis):

  • Includes both marijuana (high THC content) and hemp (low THC content).

  • CBD can be extracted from specific cannabis strains.

Cannabis Crop Anatomy and Physiology

Familiarize yourself with the plant’s structure:

  • Roots: Anchor the plant and absorb nutrients.

  • Stems: Support growth and transport water and nutrients.

  • Leaves: Photosynthesize and produce energy.

  • Flowers: Contain CBD-rich trichomes.

Understand growth stages:

  • Germination (0-1 week): Seed sprouts and develops roots.

  • Seedling (1-2 weeks): First true leaves appear.

  • Vegetative growth (2-6 weeks): Plant grows rapidly.

  • Flowering (6-12 weeks): CBD-rich flowers develop.

Best Practices

Research Specific Needs:

  • Different CBD crop varieties have unique requirements.

  • Understand optimal soil pH, water, and light conditions.

Soil Preparation and Nutrient Management:

  • Ensure well-draining soil with adequate nutrients.

  • Regular soil testing helps maintain optimal conditions.

What to Avoid

Poor Soil Conditions:

  • Avoid planting CBD crops in soil with inadequate drainage or nutrient deficiencies.

  • Soil health directly impacts crop quality and yield.

Strain Selection and Breeding

Understanding CBD Strains

Strain Genetics:

  • Research strain lineage, genetic stability, and cannabinoid profiles.

  • Focus on high CBD content and low THC content.

Breeding Techniques:

  • Selection: Choose parent plants with desired traits.

  • Hybridization: Crossbreed strains to enhance specific characteristics.

  • Genetic Testing: Validate strain purity and stability.

Selecting the Right Strain

Consider the following factors:

  • Climate: Choose strains suited to South Africa’s climate.

  • Soil: Match strains to soil types.

  • Market Demand: Identify strains popular among consumers.

  • Local Regulations: Ensure compliance with hemp-specific laws.

Best Practices:

High CBD, Low THC:

  • Opt for strains with significant CBD content and minimal THC.

  • Legal limits must not be exceeded.

Pest and Disease Resistance:

  • Select strains resilient to common pests and diseases.

What to Avoid:

Improper Breeding Practices:

  • Genetic testing is crucial to maintain strain integrity.

  • Avoid haphazard breeding without proper evaluation.


Please Note: Adherence to South African regulations are essential. Farmers have to obtain a licence and permit from the South African Health Products Regulatory Authority (SAHPRA) to legally cultivate Cannabis. These licence and permit ensure compliance with the Plant Improvement Act (PIA) and other relevant legislation12.
