Cannabis Cultivation Course

Lesson 1 • Airflow and Ventilation Design

Details oscillating fans, exhaust sizing, and negative pressure rooms. Proper airflow strengthens stems and prevents hot spots and pathogen buildup.

Lesson 2 • Lighting Systems and Spectrum Management

Compares HPS, CMH, LED, and fluorescent technologies for each growth stage. Proper spectrum and intensity drive photosynthesis efficiency and yield.

Lesson 3 • Temperature and Humidity Control

Explains stage‑specific VPD targets and basic HVAC sizing. Maintaining stable temperature and humidity prevents mould, stress, and yield loss. Includes compact charts for seedling, vegetative, and bloom stages, plus sizing guides for chillers, humidifiers, and exhaust fans.

Lesson 4 • Environmental Monitoring and Automation

Introduces sensors, controllers, and integrated grow management systems. Automation reduces human error and enables data-driven environment optimisation.

Lesson 1 • Coco Coir Cultivation Principles

Explains coco's inert nature, buffering requirements, and high-frequency fertigation. Coco enables precise nutrient control with faster growth rates than soil.

Lesson 2 • Hydroponic System Types

Compares DWC, NFT, ebb‑and‑flow, and drip systems for cannabis, emphasizing speed, control, and scalability. Summarises water volume, nutrient turnover, and root‑zone oxygenation to guide growers in choosing a setup that fits space, cycle length, and automation goals.

Lesson 3 • Container Selection and Sizing

Guides pot volume decisions, fabric vs. hard containers, and transplant timing. Container choice affects root air pruning, moisture retention, and plant size.

Lesson 4 • Root Zone Health and Oxygen

Addresses dissolved oxygen, root rot prevention, and beneficial microbes. Healthy roots are the single greatest predictor of above-ground plant performance.

Lesson 1 • Organic vs. Synthetic Nutrient Systems

Compares mineral salts, organic teas, and biostimulants for cannabis feeding. Each approach has distinct cost, complexity, and end-product quality implications.

Lesson 2 • pH and EC Management

Explains how pH governs nutrient availability and EC measures solution strength. Maintaining correct ranges prevents lockout and toxicity simultaneously.

Lesson 3 • Macronutrient Roles and Ratios

Details nitrogen, phosphorus, and potassium functions and stage-specific ratios. NPK ratios shift from veg to flower to support different metabolic demands.

Lesson 4 • Secondary and Micronutrient Functions

Covers calcium, magnesium, sulfur, iron, and trace elements. Micronutrient deficiencies often mimic other problems; accurate diagnosis is essential.

Lesson 1 • Cannabis Genetics and Heredity

Explains Mendelian inheritance, dominant/recessive traits, and polygenic expression. Enables breeders to predict offspring phenotypes accurately.

Lesson 2 • Plant Anatomy and Physiology

Reviews roots, stems, leaves, and reproductive parts, linking anatomy to nutrient uptake, light capture, and yield. Understanding vascular pathways and leaf shape lets growers fine‑tune irrigation, fertilisation, and lighting to boost biomass and cannabinoid production.

Lesson 3 • Sex Determination and Hermaphroditism

Details chromosomal sex determination and environmental triggers for hermaphroditism. Critical for maintaining sinsemilla crops and seed production.

Lesson 4 • Cannabinoids and Terpene Biosynthesis

Outlines biochemical pathways to THC, CBD, and terpenes, connecting genetics and environment to flower profile. Mapping key enzymes like MEP, MVA, and terpene synthases lets growers adjust light spectra, temperature, and nutrients to achieve desired potency and aroma.

Lesson 1 • Mainlining and Manifolding

Teaches symmetrical branching structures that create uniform cola development. Mainlining requires longer veg but produces highly predictable, even harvests.

Lesson 2 • Low-Stress Training Techniques

Covers bending, tying, and ScrOG methods to spread canopy without wounding. LST increases bud sites while maintaining plant vigour and recovery speed.

Lesson 3 • SCROG and SOG Systems

Compares screen of green and sea of green for different space and clone scenarios. SOG maximises turnover speed; SCROG maximises per-plant yield.

Lesson 4 • Lollipopping and Defoliation

Details lower canopy removal and strategic leaf stripping to improve airflow and light. Reduces popcorn buds and concentrates energy into top colas.

Lesson 1 • Vegetative Growth Phase

Covers node development, canopy spread, and root growth. Explains how photoperiod, nutrient ratios, and veg training affect internodal spacing, leaf area, and root mass, influencing the plant’s ability to produce abundant bud sites during flowering.

Lesson 2 • Flowering Initiation and Progression

Details photoperiod triggers, pistil development, and bud site formation. Connects light cycle management to flower density and resin production.

Lesson 3 • Germination and Seedling Development

Explains seed viability, germination cues, and early seedling care. Highlights optimal moisture, temperature, and sterile media to promote uniform cotyledon emergence, strong taproot growth, and reduced damping‑off risk, establishing a solid foundation.

Lesson 4 • Ripening and Harvest Readiness

Teaches trichome assessment, pistil colour changes, and calyx swelling as harvest indicators. Ensures peak cannabinoid and terpene preservation.

Lesson 1 • Biological Control Agents

Introduces predatory insects, beneficial nematodes, and microbial pesticides. Biocontrols form the cornerstone of sustainable IPM without chemical residues.

Lesson 2 • Organic and Chemical Pesticide Use

Compares neem oil, insecticidal soaps, spinosad, and synthetic options by efficacy and residue risk. Pesticide selection must consider harvest proximity and safety.

Lesson 3 • Common Cannabis Pests Identification

Covers spider mites, fungus gnats, thrips, aphids, and russet mites. Early identification through scouting prevents population explosions and crop loss.

Lesson 4 • Fungal and Bacterial Pathogens

Identifies botrytis, powdery mildew, fusarium, and pythium by symptom. Environmental control is the primary defence against all major cannabis pathogens.

Lesson 1 • Harvest Timing and Execution

Covers trichome assessment tools, whole-plant vs. staged harvest, and sanitation. Harvest timing is the final determinant of cannabinoid and terpene peak.

Lesson 2 • Dry Trimming and Manicuring

Covers dry trim timing, hand vs. machine finishing, and quality grading. Dry trimming preserves trichomes better but requires more labour than wet trimming.

Lesson 3 • Drying Room Setup and Management

Details temperature, humidity, and airflow targets for a 10–14 day dry. Slow drying preserves terpenes and prevents harsh smoke from rapid moisture loss.

Lesson 4 • Bucking and Wet Trimming

Explains branch removal, wet trimming workflow, and machine vs. hand trim tradeoffs. Trim quality directly affects bag appeal and market value of flower.
