| Temperature | Maintain 70-85°F (21-29°C) during lights on, and 60-75°F (15-24°C) during lights off. Avoid temperatures above 85°F which can stress plants. |
| Humidity | Keep relative humidity between 40-60% during flowering to prevent mold. Start at 65-80% for seedlings and gradually lower to 40-50% by late flowering. |
| Airflow | Ensure good air circulation with fans to strengthen stems and prevent microclimates that encourage pests and diseases. Avoid pointing fans directly at plants. |
| CO2 | Supplement CO2 levels up to 1200 ppm during flowering to boost growth. Increase levels gradually in line with light intensity. |
Common challenges include temperature and humidity fluctuations, insufficient airflow, and inconsistent light cycles. Monitor conditions closely and use a combination of ventilation, air conditioning, dehumidifiers, and environmental controllers to maintain optimal parameters. Adjusting lighting schedules and intensity can help simulate seasonal changes and control stretching.
Harvest, Dry, Cure Properly
Here is a brief overview of key harvesting and curing guidelines for cannabis:
- Harvest timing: The ideal time to harvest is when the majority of the trichomes on the buds have turned milky white and the pistils have darkened and started to curl. Harvesting too early can result in less potent buds, while harvesting too late can lead to a decline in quality.
- Harvesting techniques: Cut the plant at its base and hang it upside down to dry in a controlled environment around 60-70°F (15-21°C) with 45-55% humidity. Alternatively, cut individual branches and trim off fan leaves before drying on racks.
- Trimming: Trim buds by removing excess foliage to improve appearance and airflow. Wet trimming is done immediately after harvest, while dry trimming is performed after the initial drying phase. Each method has its pros and cons for ease, final quality, and trichome preservation.
- Drying: Dry buds slowly over 7-12 days, monitoring closely to avoid overdrying. Buds are ready for curing when small stems snap rather than bend.
- Curing: Place dried buds in airtight glass jars stored in a cool, dark place. “Burp” jars daily for the first week to release moisture, then less frequently over 2-4 weeks. Proper curing preserves potency and enhances flavor by breaking down chlorophyll and distributing moisture evenly.
Drying and curing are critical for achieving optimal potency, aroma, and flavor. Rushing the process can result in harsh, grassy-tasting buds that lack full cannabinoid and terpene expression. Proper techniques ensure a smoother smoke and more enjoyable experience overall.
