Marijuana Grow Basics

Pre-Flowering

Cannabis grown from seed grows pre-flowers after the fourth week of vegetative growth. They generally appear between the fourth and sixths node from the bottom f the plant. Cannabis plants are normally either all male or all female. However, occasionally an intersex plant with both male and female flowers will appear. Each sex has its own distinct flowers. Pre-flowers will be either male or female. Growers remove and destroy the males (or use them for breeding stock) because they have low levels of cannabinoids (chemical components of marijuana: THC, CBD, CBN, etc.). the most desirable female plants are cultivated for their high THC content.
