How to determine if your plant is ready for harvest
Trichomes
Trichomes are tiny, hair-like structures found on the surfaces of plants that produce and secrete various substances, including cannabinoids, terpenes, and flavonoids. The maturity of trichomes is one way to determine when a cannabis plant is ready to be harvested.
You will need a magnifying tool such as a jeweler's loupe or a handheld microscope to monitor the trichomes. You can then examine the trichomes on the plant's flowers (buds) and leaves. As the trichomes mature, they will change color and become more transparent.
When the trichomes are clear or milky white, this indicates that the plant is not yet ready to be harvested. When the trichomes turn amber or brown, this means that the plant is approaching peak maturity and may be prepared to be harvested. However, the best time to reap will depend on the specific strain of cannabis and the desired effects.
It is important to note that the maturity of the trichomes is just one factor to consider when determining when to harvest a cannabis plant. Other factors include the plant's growth stage, the buds' size and density, and the plant's overall appearance.
Harvesting Guide with Optimal Drying Temperature and Humidity Levels
Drying is crucial in preserving terpenes and cannabinoids, and the right conditions can make a significant difference. The ideal drying cycle generally ranges between 7 to 14 days, depending on various factors like environmental conditions and plant size. Below is a basic guideline for a 10-day drying cycle with optimal temperature and humidity settings for each day:
Day | Temperature (°F / °C) | Relative Humidity (%) | Notes |
1 | 65°F / 18°C | 55-60% | High humidity to start, avoiding quick drying. |
2 | 65°F / 18°C | 55-60% | Maintain a stable environment. |
3 | 65°F / 18°C | 55-60% | Watch for mold and ensure good air circulation. |
4 | 65°F / 18°C | 50-55% | Gradually reduce humidity. |
5 | 65°F / 18°C | 50-55% | Check stems for flexibility and adjust if needed. |
6 | 65°F / 18°C | 45-50% | Continue monitoring the stems. They should be less bendy. |
7 | 65°F / 18°C | 45-50% | Buds should feel drier to the touch. |
8 | 65°F / 18°C | 40-45% | Lower humidity to finalize drying. |
9 | 65°F / 18°C | 40-45% | Check for consistent drying across buds. |
10 | 65°F / 18°C | 40-45% | Buds should be ready for curing. |
Key Points:
- Temperature: Keeping a consistent temperature of around 65°F (18°C) is ideal. This temperature range is conducive to a slow, even drying process, which is critical for preserving quality.
- Humidity: Starting with a higher relative humidity (55-60%) prevents the flowers from drying too quickly, which can degrade terpenes. Gradually lowering the humidity throughout the drying period helps to avoid mold or mildew formation while ensuring a thorough drying.
- Air Circulation: Good air circulation is crucial throughout the drying process, but avoid direct airflow on the buds to prevent uneven drying.
- Observation: Regularly check the buds and stems. The stems should snap, not bend when the buds are adequately dried.
- Adjustments: Be prepared to adjust the humidity and temperature based on your specific environment and the condition of the buds.
It is also essential to handle the cannabis gently during the drying process to avoid damaging the trichomes and other delicate structures on the plant.
