Question to Gemini: Is VDP a good measurement to follow when drying cannabis

Answer: No, VPD (Vapor Pressure Deficit) is not generally considered a good measurement to directly follow when drying cannabis.
Here's why:
  • Different goals: VPD is ideal for regulating plant growth and health. Drying cannabis focuses on moisture removal to preserve the bud while minimizing degradation.
  • Static vs dynamic environment: VPD thrives in a dynamic environment where factors like temperature and humidity can fluctuate slightly to achieve the targeted VPD. Drying cannabis requires a more static environment with specific temperature and humidity ranges to promote slow, even drying.
What to focus on instead:
  • Temperature: Aim for a cool drying space, ideally between 60-68°F (15-20°C). Higher temperatures can accelerate drying and degrade cannabinoids and terpenes.
  • Humidity: Maintain a relative humidity (RH) between 50-60%. Too high and you risk mold growth, too low and the buds dry out too fast, affecting quality.
Alternative methods for monitoring drying cannabis:
  • Feel: The buds should feel dry to the touch but still have a slight give when squeezed gently.
  • Stems: The small stems inside the buds should snap easily when bent.

Is VDP a good measurement to follow when drying cannabis

Vapor Pressure Deficit (VPD) can be a useful measurement to consider when drying cannabis, but it's not typically the primary measurement used for this process. VPD is more commonly used during the growing phase to optimize environmental conditions for plant growth.
When drying cannabis, the key factors typically monitored include humidity levels, temperature, airflow, and light exposure. These factors collectively influence the drying process and the quality of the final product. Here are some considerations:
  1. Humidity Control: Maintaining the right humidity levels (usually around 50-60% relative humidity) helps prevent mold growth and ensures a controlled drying process.
  2. Temperature: Moderate temperatures (around 60-70°F or 15-21°C) are generally ideal for drying cannabis. Higher temperatures can speed up drying but may degrade cannabinoids and terpenes.
  3. Airflow: Proper airflow is crucial to ensure even drying and prevent mold. However, too much airflow can dry the cannabis too quickly.
  4. Light Exposure: Cannabis should be dried in a dark environment to preserve cannabinoids and terpenes.
While VPD could theoretically guide humidity control during drying, it's more practical to directly monitor and adjust relative humidity using a hygrometer. VPD is more relevant in the context of cultivation where it helps optimize conditions for plant growth and transpiration.
In conclusion, while VPD is not typically used as a direct measurement during cannabis drying, understanding basic principles of humidity, temperature, airflow, and light exposure is essential for achieving a high-quality final product.

Does anyone know if a camara's IR night vision lights would impact flowers in any way during the dry cycle? I thought it might be cool to hook up a wyze cam and do a time lapse inside a Koolatrol. Thoughts?

I don’t have scientific data, but from everything I’ve read it’s the uv light that does the most damage to thc, so i would think the ir light from a camera would have little to no effect. The heat generated by the lights and camera may be a different story. I didn’t cover the glass on my koolatron because it blocks uv, and for me that was good enough.

Thanks, thought it would be cool to get a timelapse of flowers shriveling. I'll think about it.

I got my fridge and got everything wired up and my racks zip tied with grill mesh. Doing a 24 hour run with baking soda in my garden shed as a test. I set it to 58 and it started out with 80 reading. Just checked on it and it's reading 58 and it's 101 in the shed. VERY surprised. I won't be leaving it there but wanted to see what it could handle. Harvesting tomorrow!

My ac infinity probe actually clocks it 2 degrees lower than my fridge usually says.

Im gonna be using an ac infinity too. Have the probe wired but haven't powered it up yet. Waiting for the plug for the dehumidifier.

Got mine hooked up and the ac infinity probe is clocking 1-2 higher than the fridge display. Where did you guys fix your probe inside the fridge?

After back to back crop failure due to bud rot during the drying process, with another crop at least a month from harvest, I just bit the bullet and bought the thermoelectric wine cooler and dehumidifier. I already have the Inkbird, still in its box.

Going to be studying this thread closely. Appreciate the work yall put in to make this so straightforward.
