As a preface: I live in a tropical country, and this is my first time winterizing my VFTs.
I still have a bit of time before actual winter season in the Northern Hemisphere, so I had been thinking of making a dormancy box for my plants out of an icebox and a thermoelectric cooling device (TEC) to more-or-less synchronize with the actual VFT growing season in the wild.
The main idea is to keep the plants in the icebox, with a light inside that should simulate sunlight, and the TEC to cool down the box. Sensors will be attached as well to monitor the temperature and humidity, and automatically cool down the box when it gets too warm or humid, and shut down when it gets too cold or dry.
What I was wondering about was:
- Is a range of 6-10 degrees C (43-50F) in the box okay?
- How bright is winter sunlight compared to summer?
- Do I really need to keep the humidity in check as well?
