Welcome to the most extensive and up to date Cannabis cultivation guide

The 9 factors that determine cannabis growth (and yield) are as follows: (in order of importance)

• Light
• Nutrients
• Water
• Humidity + Temperature (Vapour pressure deficiency)
• Oxygen
• CO2
• Wind
• Root temperature

These factors are all connected! Raising the temperature can increase relative humidity, increasing light intensity will require more nutrients to support photosynthesis, poor soil pH can lead to nutrient lockout etc.
