Description

Please Dry the Herbs Before Curing

Drying (Before Using the Curing Jar)

Purpose

Remove most of the surface and internal free moisture to prevent mold and bacterial growth.

Process

Usually carried out in a well-ventilated space at a moderate temperature (around 18–24°C / 65–75°F) and relative humidity of 45–55% for several days to two weeks, until stems snap rather than bend.

Use

Prepares the material for curing and prevents spoilage or quality loss during storage due to excess moisture.

Curing

Purpose

Under controlled humidity and temperature, allow remaining moisture in plant tissues to slowly redistribute, while breaking down chlorophyll, sugars, and starches. This reduces harshness and enhances flavor, aroma, and overall user experience.

Process

Typically done in an airtight container, “burping” (briefly opening) daily to exchange air, maintaining humidity at 55–65% and temperature at 18–21°C (65–70°F) for 2–8 weeks.

Use

Improves taste and aroma

Stabilizes chemical compounds (e.g., terpenes, active ingredients)

Extends shelf life

Tips

A. Please put dried and trimmed buds in jars

B. The curing jar itself cannot regulate the temperature and humidity inside the jar. Additional tools may be used if necessary.

Temperature

Regulate the temperature inside the tank by adjusting the temperature of the environment in which the tank is placed using air conditioning, heaters, or other devices.

Humidity

A two-way humidity pack between 55% and 62% can be placed inside the tank as needed. It is recommended that the humidity pack be replaced every 90 days.

C. The jar does not actively draw in fresh air. However, because of the built-in vacuum system, a small amount of air will naturally flow in. For optimal curing results, we recommend opening the jar at regular intervals to allow a full exchange of fresh air.
