Thank you,
fan is 4,7" computer fan ( good one ), and 2 food grade containers are 13"x10" and 2" high.
Rubber band is good to keep cloth tight.
You need low voltage power supply where you can change output voltage (adjust fan speed -> humidity ).
Because there is electricity and water so I use it my own risk.
And remember low electricity 2-12volt transformer ( it must be ).
