Any ideas?

Ask in alt.smokers.cigars Lots of humidor building knowledge in there,
even for these big humidors.

On the whole though, I wouldn't bother. Use simple 50% propylene glycol
as a humectant and let equilibrium chemistry keep the humidity correct.
Monitor it electronically if you like, but unless this is a shop humidor
with a large _turnover_ in contents, then once the humdity is correct,
it will stay stable. Big ones are even more stable than small ones, so
long as the humidifier is large enough.
