Dankubator DIY Cannabis Drying System
Don't Hate, Dankubate! State of the Art Cannabis Drying System for $500!
The Dankubator is similar to a Cannatrol or other drying systems. Dankubator measures up with the most sophisticated drying system by targeting a consistent VPD. VPD is controlled by managing the temperature and RH of the environment.
Instructions will be posted at this link
Dankubator consists of (exact parts list will be shared at the bottom of this post)
- A modified food-grade storage container
- Electronic dampers
- Thermoelectric Coolers
- Fans
- Atmospheric Pressure Sensor
- Temperature Sensors
- Humidity Sensors
- Rasberry Pi or other controller
What makes Dankubator unique?
- Reverse pressure for lower temperature moisture extraction
- Targets VPD so regardless of ambient temperature or RH we can find the right combo for optimal moisture extraction rates
- Commercial-grade software algorithms running in Python
How does it work?
- VPD tells us how fast or slow moisture will be extracted from the bud
- Hotter temps increase the rate of extraction, colder reduces it
- Less humidity increases the rate of extraction, more reduces it
- Too much moisture can cause mold
- Too much heat, cold, or dryness can damage cannabinoids and terpenes
- Danukubator takes all of this into consideration and targets a configurable VPD (default is about .8 kPa) while trying to also stay within optimal temps and humidity for healthy trichomes, terpenes, and flavonoids.
- It uses variable power to coolers and fans, by using PWM technology and a PID algorithm, to adjust power to the proper controls in proportional to the error rate.
- The code is open source and the plans are completely free.
