1. Should I use a dehumidifier in my drying room?

Using a dehumidifier in your drying room can be beneficial to achieve ideal drying conditions. It allows you to control the relative humidity, keeping it at an optimal level (usually around 45-60%) to prevent mold growth while allowing the cannabis to dry properly.

2. How do I lower the humidity in my dry room?

If the humidity in your dry room is too high, there are several ways to lower it. One common method is to use a dehumidifier, which removes moisture from the air. You could also improve ventilation or use materials that naturally absorb moisture, such as desiccants.

3. Should you leave a dehumidifier on all the time?

Whether or not to leave a dehumidifier on all the time depends on the conditions in your drying room. If the room tends to maintain high humidity levels, then continuous operation might be necessary. However, if the humidity levels fluctuate, a dehumidifier with a built-in hygrometer can switch on and off as needed.
