any opinions on a good humidifier for a humidor?
Check out www.cellarmate.com. I have seen many of these systems in very high end applications and the prices are somewhat reasonable.
I'm not trying to cool it just humidify it...thanks anyway
That's a real specialty, and unless you're designing a large unit for a store, you're better off buying one made especially for that purpose. Check out this page: http://www.humidor-guide.com/
