Cannabis cultivation

Botany and Species:

• Cannabis belongs to the genus Cannabis in the family Cannabaceae.
• Three main species: Cannabis indica, Cannabis sativa, and Cannabis ruderalis.
• Dioecious annual plant.
• Female plants produce THC with changing seasons.
• Existence of commercial hybrids with ruderalis, indica, and/or sativa genes.

Cultivation Requirements:

• Soil is essential unless using hydroponic or aeroponic methods.
• Nutrient importance indicated by N-P-K percentages.
• Optimal soil pH range of 5.8 to 6.5.
• Ideal day temperature range: 24 to 30°C.
• Humidity levels of 40–60% RH are optimal for growth.

Growth Medium and Care:

• Soil is required, with proper nutrients and pH.
• Temperature range of 24 to 30°C and humidity of 40–60% RH ideal.
• Watering frequency and amount crucial, avoiding over-saturation.
• Signs of water issues include leaf wilting.
• Duration, indicators, and readiness for vegetative and flowering stages.

Lighting and Nutrient Management:

• Use of sunlight or grow lights for growth.
• Light schedule impacts vegetative growth and flowering.
• Flowering triggered by darkness-induced hormonal reactions.
• Nutrient requirements, fertilizers high in nitrogen and potassium.
• Gradual increase in fertilizer strength as plants grow.

Advanced Cultivation Techniques and Growth Factors:

• Training methods like SCROG and SOG, super cropping, and LST.
• Specific systems used such as NIMBY no-dump, Hempy Bucket, and Krusty Freedom Bucket.
• Research in medicinal cannabis cultivation, focusing on medicines like Marinol.
• Factors influencing growth: plant size, light, space, strain, and micronutrient fertilizers.
• Strain characteristics affecting growth patterns and cultivation techniques.
