Harvesting and Curing

Harvest Signs

OG Sour Diesel plants are typically ready for harvest when 70-90% of the pistils have darkened and curled in. Trichomes should be inspected with a magnifying glass; harvest time is ideal when most trichomes are milky white with some amber. Clear trichomes indicate the plant is not yet fully mature, while too many amber trichomes can mean the plant is overripe.

Harvesting Techniques

Begin by cutting the main stem at the base using sharp, sterilized scissors. Remove large fan leaves to allow easier access to the buds. Proceed to cut away smaller leaves and branches, working from the bottom up, separating the buds from the plant. Trim over a screen to collect trichomes that fall off during the process. This kief can be used separately for its concentrated potency.

Drying and Curing

Drying should occur in a controlled environment with temperatures around 60-70°F and humidity levels at 45-55%. Hang the trimmed buds upside down in a dark room with good air circulation. Drying typically takes 7-14 days. Once stems snap rather than bend, buds are ready for curing. Place the dried buds in airtight containers, opening them several times a day for the first week to allow moisture to escape and fresh air to enter. Continue this process for 2-4 weeks to fully develop the flavor and potency of the OG Sour Diesel strain.

Storage

Store cured OG Sour Diesel buds in airtight containers, such as glass jars, in a cool, dark place to preserve their quality. Avoid plastic bags or containers as they can impart unwanted flavors and may not protect against humidity changes. Containers should be kept away from direct sunlight and any heat sources to maintain the integrity of the cannabinoids and terpenes.

Site Selection and Preparation

Location

Selecting a location for OG Sour Diesel requires attention to sunlight exposure, as the plant thrives in areas that receive ample daily sunlight.
