Importance of Humidity Control During Curing

Controlling humidity during the curing process is essential for several reasons:

  • Flavor: Proper humidity levels help preserve the terpene profile of the cannabis, ensuring a pleasant taste and aroma.
  • Potency: Correct humidity levels protect the trichomes containing the plant’s active compounds like THC and CBD from damage and degradation.
  • Texture and Feel: A well-cured bud should have a balanced moisture content to provide a smooth and enjoyable smoking experience.
  • Mold Prevention: Proper humidity control prevents mold growth, ensuring a safe and healthy product.

Tools for Measuring Humidity

Various tools are available to measure humidity in curing jars, including hygrometers and humidity packs.

Let’s explore these options in more detail.

Hygrometers

Hygrometers

Hygrometers are instruments used to measure the environment’s relative humidity (RH).

When placed inside a curing jar, a hygrometer can accurately read the humidity level.

Digital hygrometers are preferred for their ease of use, accuracy, and ability to display temperature and humidity readings.

Tips for using hygrometers:

  • Regularly calibrate your hygrometer to ensure accurate readings.
  • Place the hygrometer inside the jar to monitor humidity levels in real time.

Humidity Packs

Humidity packs, like Boveda packs, are two-way humidity control packets that help maintain a consistent RH level inside a curing jar.

These packs are available in various RH percentages and are easy to use.

Tips for using humidity packs:

  • Choose the appropriate RH percentage for your desired curing environment (usually 58-62% RH).
  • Replace the packs as needed to maintain consistent humidity levels.

Methods to Lower Humidity in Curing Jars

If the humidity inside your curing jar is too high, you can use several methods to lower it and maintain an optimal curing environment.

Desiccant Pouch Method

Desiccant Pouch Method

Desiccant pouches, like silica gel packets, can help lower humidity by absorbing excess moisture.

Place the desiccant pouch inside the curing jar, close the lid, and monitor the humidity level using a hygrometer.

Replace the pouch as needed to maintain the desired humidity level.

Moisture-Absorbing Substance Method

Moisture-Absorbing Substance Method

Moisture-absorbing substances like humidity packs, peat moss, or baking soda can lower humidity in curing jars.

Place your chosen substance in a small container or breathable pouch and add it to the jar.

Monitor the humidity level using a hygrometer and replace or recharge the substance as needed.

Potential Risks of High Humidity

High humidity in curing jars can lead to several issues, including mold growth, reduced potency, and loss of flavor.

Here’s how to prevent and address these problems:

Mold Growth

Mold thrives in high-humidity environments and can ruin your cannabis.

To prevent mold growth:

  • During curing, maintain proper humidity levels (between 58-62% RH).
  • Regularly inspect your cannabis for signs of mold and remove any affected buds.

Reduced Potency and Flavor

High humidity can damage trichomes and negatively affect the terpene profile, reducing potency and flavor.

To avoid these issues:

  • Maintain the appropriate humidity level throughout the curing process.
  • Store cured cannabis in an airtight container in a cool, dark place to preserve its quality.

FAQ

How do you control humidity when curing?

To control humidity during curing, use tools like hygrometers to monitor humidity levels and humidity packs or desiccant pouches to maintain the desired RH range (58-62%). Regularly “burp” the jars by opening them briefly to allow air exchange and ensure even moisture distribution.

What humidity is too high for curing?

Humidity levels above 65% RH are considered too high for curing cannabis, as they can promote mold growth and negatively affect the quality of your buds.

What should the humidity be in cure jars?

The ideal humidity level in curing jars should be between 58-62% RH. This range helps preserve the cannabis’s flavor, potency, and overall quality while preventing mold growth.

Is 50% humidity too low for curing?

A 50% humidity level might be too low for curing, as it can cause the marijuana to dry out too quickly, leading to harsh, less flavorful buds. Aim for a humidity level between 58-62% RH for optimal curing results.

Can mold grow in 50 humidity?

While mold growth is less likely at 50% humidity, it’s still possible if other conditions are favorable, such as high temperatures or poor air circulation. Aim for a humidity level between 58-62% RH and regularly inspect your cannabis for signs of mold.

Is 8 percent humidity dry?

Yes, 8% humidity is considered very dry. Low humidity levels can cause the cannabis to dry out too quickly, resulting in a harsh, less enjoyable smoking experience. To properly cure your marijuana, maintain a humidity level between 58-62% RH.
