Questions about dryboxing

In the summers here, the humidity can get quite high so I have been thinking about dryboxing. I really have no clue how to go about it though so I had a few questions and I was hoping someone could help me out.

Question 1- Can I use a cigar box, or does it have to be a humidor?

I have a small 20 count humi and a few spare boxes. Obviously I would like to use a plain box so I can keep the humi for cigars . I know that boxes wont hold humidity that well, but I wasn't sure if it would be as much of a problem when dryboxing.

Question 2- Do I need humidification?

Well I guess the real question would be what is the optimum humidity for dryboxing, and do I need humidification for it?

Question 3- Assuming I get a drybox up and running, how long should I do it for, or how do you know when they are ready?



Thanks for reading and advice! Cheers!
