Harvesting and Curing

Harvest Signs

Jack 47 plants are typically ready for harvest when 50-70% of the pistils have darkened and curled in. Trichomes should be inspected with a magnifying glass; harvest time is optimal when most trichomes are milky white with some turning amber. Clear trichomes indicate the plant is not yet fully mature, while too many amber trichomes suggest the plant may be overripe, leading to a more sedative effect.

Harvesting Techniques

Proper harvesting of Jack 47 involves cutting the plant at its base using sharp, sterilized scissors or shears. Begin trimming away large fan leaves and then remove smaller sugar leaves to expose the buds. Trim over a screen or tray to collect trichome-rich trimmings for later use. Cut the branches into manageable sections to prepare for drying.

Drying and Curing

Drying should occur in a controlled environment with temperatures around 60-70°F and humidity levels between 45-55%. Hang branches upside down in a dark room with good air circulation. Drying typically takes 7-14 days; buds are ready when stems snap rather than bend. Curing involves placing the dried buds in airtight containers, opening them several times a day for the first week to allow moisture to escape and for air exchange. Continue this process for 2-4 weeks to develop flavor and potency.

Storage

Store cured Jack 47 buds in airtight containers made of glass or food-grade stainless steel, away from direct sunlight and in a cool environment.
