What Is the 60 60 Rule for Drying Cannabis

The 60-60 Rule for drying cannabis is a guideline used by growers to ensure an optimal drying process. It refers to maintaining:

✅ 60% Relative Humidity (RH)
✅ 60°F (15-16°C) Temperature

Benefits of the 60-60 Rule

Prevents mold growth by avoiding excess moisture.

Slows down drying to enhance terpene retention and smoothness.

Reduces chlorophyll breakdown gradually, improving flavor.

Typically 10-14 days, depending on factors like bud density and airflow.

Select a professional industrial-size dehumidifier for precise humidity control.

Ensure it's sized appropriately for your drying space.

Install the cannabis dehumidifier outside the direct airflow of the buds to avoid uneven drying.

Keep it near humidity hotspots (e.g., near freshly harvested plants).

Ensure proper air circulation by using oscillating fans, but avoid direct airflow on buds.

Start at 60% RH and monitor with a hygrometer.

Avoid dropping humidity too quickly—gradual drying is key for preserving terpenes.

Use an air conditioner or HVAC system if the temperature rises above 60°F.

Avoid using space heaters, as they can dry buds too fast.

Many dehumidifiers come with built-in humidistats—use them to maintain a steady 60% RH.

Avoid over-drying by adjusting settings as buds lose moisture.

Empty the water tank or set up a drainage hose for continuous operation.

Clean filters regularly to maintain efficiency.

Check for clogs or buildup in the drainage system.

Use multiple hygrometers in different spots to detect microclimates.

If RH drops too low, use a humidifier or slightly increase plant material in the room.

If RH rises too high, increase dehumidifier power or improve ventilation.
