Harvesting cannabis is one of the most important phases of the cultivation process, directly determining the potency, flavor, and overall quality of your final product. While growing cannabis demands time, effort, and attention to detail, harvesting is where all your hard work pays off. By mastering the timing, techniques, and post-harvest processes, cultivators can maximize their yield and create a product that stands out in quality.
In this guide, we’ll explore the optimal cannabis harvest time, step-by-step harvesting methods, drying and curing techniques, and some common pitfalls to avoid. We’ll also discuss advanced tips to help even experienced growers refine their processes.
Why Proper Cannabis Harvesting Matters
Harvesting cannabis at the right time and using the correct methods is crucial for several reasons:
Maximizing Potency
Cannabinoids like THC and CBD are at their peak potency only during specific stages of the plant’s maturity. Harvesting too early can result in lower levels of these compounds, while delaying too long can cause THC to degrade into CBN, which has less psychoactive effects and a more sedative quality.
Enhancing Flavor and Aroma
Terpenes are responsible for cannabis’s distinct aroma and flavor. These volatile compounds can easily degrade if the plant is harvested too late or mishandled during drying and curing. Proper harvesting ensures the preservation of terpenes, which enhances the sensory experience for consumers.
Preventing Loss of Quality
Mature cannabis plants left unharvested for too long begin to lose their cannabinoids and terpenes, resulting in buds that are less flavorful, less potent, and less enjoyable. Harvesting at the right time ensures that your hard work yields the best possible product.
Identifying the Optimal Cannabis Harvest Time
Timing is everything when it comes to harvesting cannabis. Observing physical changes in your plants is the best way to determine readiness.
Trichome Color Guide for Harvesting
Trichomes are tiny, mushroom-shaped crystals on cannabis flowers that house cannabinoids and terpenes. Observing their color under a magnifying tool (like a jeweler’s loupe) is the most reliable way to determine if your plant is ready:
- Clear Trichomes: Indicate the plant is still maturing and not yet ready.
- Milky or Cloudy Trichomes: Signal peak cannabinoid levels. Harvesting at this stage provides the most potent effects, particularly for strains high in THC.
- Amber Trichomes: Suggest that THC is starting to degrade into CBN. Harvesting now will produce a more sedative effect.
Observing Pistils for Readiness
Pistils, the hair-like structures on cannabis flowers, can also provide clues about maturity:
- White Pistils: Immature flowers that need more time to develop.
- Orange or Brown Pistils: When 70-80% of pistils have darkened and curled inward, your cannabis is typically ready to harvest.
Note: Some strains may still produce white pistils even though the trichomes show it is ready to harvest. For the best accuracy, look at the trichomes.
Additional Tips for Timing
- Check plants daily during the final stages of flowering, as trichome color and pistil development can change rapidly.
- Harvesting at different stages of trichome maturity can produce varying effects, giving you greater control over your cannabis’s final result.
Step-by-Step Guide to Harvesting Cannabis
Step 1: Gather Your Tools and Set Up Your Workspace
Preparation is key for a smooth harvesting process. Ensure you have the following tools and supplies ready:
- Sharp pruning shears or scissors for cutting plants and branches. We recommend the AC Infinity 6.6” Stainless Steel Curved Pruning Shears for the best results.
- Disposable gloves to prevent contamination.
- Drying racks or hangers to hang plants during drying.
- Glass jars or Curing bags to cure your buds in. We highly recommend using TerpLoc Bags for curing and storing your cannabis.
- A clean, dark, and well-ventilated workspace to minimize the risk of mold and other contaminants.
Step 2: Cutting the Plants
There are two primary methods to harvest your plants:
- Whole-Plant Harvesting: Cut the entire plant at the base. This is ideal for growers with plenty of drying space.
- Branch-by-Branch Harvesting: Cut one branch at a time, which works better for smaller drying setups. This method also allows you to selectively harvest buds that have reached full maturity while leaving others to continue ripening.
Step 3: Trimming
Wet Trimming vs. Dry Trimming:
- Wet Trimming: Immediately remove the large fan leaves and sugar leaves (the smaller, trichome-coated leaves near the buds). This method speeds up the drying process and reduces the chance of mold.
- Dry Trimming: Leave sugar leaves intact during drying to protect trichomes. Once the buds are fully dried, trim the sugar leaves for a more polished final product.
Note: Wet trimming is best in high-humidity environments. We recommend dry trimming unless wet trimming is needed to reduce the chances of mold.
Pro Tip: When trimming, use a Trim Bin to catch all the fallen material and sift it for you to collect dry sift hash.
Drying Cannabis for Optimal Quality
Drying is a critical post-harvest step that preserves the cannabinoids and terpenes in your buds. Here’s how to do it right:
- Temperature and Humidity: Maintain a temperature of 60-70°F (15-21°C) and a humidity level of 50-62%. A hygrometer can help monitor these conditions.
- Air Circulation: Use fans to ensure good airflow in the drying area, but avoid directing air directly at the plants to prevent uneven drying.
- Duration: Drying typically takes 7-14 days. The buds are ready for curing when the smaller stems snap cleanly rather than bending.
Curing Cannabis for Maximum Flavor and Potency
Curing is the process of slowly removing residual moisture from the buds while enhancing their flavor, aroma, and effects. Here’s how to cure cannabis properly:
- Transfer to Airtight Container: Place dried buds into airtight glass jars or curing bags, filling them about 75% to allow room for airflow.
- Burping the Jars: Open the jars once daily for the first week to release moisture and exchange air. Gradually reduce the frequency of burping over the next few weeks. Burping is not needed if you use curing bags.
- Storage Conditions: Keep the container in a cool, dark place to prevent degradation of cannabinoids and terpenes.
- Duration: Curing can take anywhere from 2 weeks to several months. The longer you cure, the smoother and more flavorful the final product becomes.
Avoiding Common Cannabis Harvesting Mistakes
Premature Harvesting
Harvesting too early results in buds with lower potency and underdeveloped flavors. Always wait until the trichomes and pistils indicate readiness.
Improper Drying
Failing to dry buds properly can lead to mold or overdrying, which diminishes the quality of cannabinoids and terpenes.
Skipping the Curing Process
Neglecting curing results in harsh, unpleasant smoke and unrefined flavors. Always take the time to cure your cannabis for the best results.
Advanced Cannabis Harvesting Tips
Morning Harvest for Terpene Retention
Terpenes are most stable early in the morning. Harvesting during this time helps preserve the aromatic compounds that define the flavor and scent of your cannabis.
Staggered Harvesting for Perfect Maturity
Not all buds mature at the same rate. Harvesting in stages allows you to pick each bud at its peak ripeness, improving the overall quality of your yield.
Monitor Drying and Curing Conditions
Invest in tools like hygrometers and climate control systems to maintain consistent temperature and humidity during drying and curing. Small fluctuations can make a big difference in the final product.
FAQs About Harvesting Cannabis
The best way to determine if your cannabis is ready for harvest is to observe the trichomes. Use a magnifying tool to check trichomes. Harvest when most trichomes are milky or cloudy with a few amber ones.
Harvesting too early results in buds with lower potency and undeveloped terpenes, leading to a less satisfying flavor and aroma. Harvesting too late can cause THC to degrade into CBN, which produces a sedative effect. Overripe buds may also lose their flavor and aroma.
Drying typically takes 7-14 days, depending on environmental conditions. Buds are ready when smaller stems snap instead of bending.
Maintain a temperature between 60-70°F (15-21°C) and humidity levels of 50-62%. Use a hygrometer to monitor these conditions.
Save sugar leaves as they often contain trichomes. You can use them to make edibles, tinctures, or cannabis concentrates like hash or kief.
Ensure proper airflow, monitor humidity with a hygrometer, and avoid overpacking the container during curing. Always dry your cannabis thoroughly before curing to reduce the risk of mold. If you live in a high-humidity climate, then it may be best to wet trim.
