Well,
To be honest, I think it will be difficult to keep the temp below 70 this time of year (especially with us reaching 106-108 every day here in Dallas). My best recommendation for you would be to get a wine fridge set up or freeze all of your cigars to prevent beetle infestation. I have a desktop unit that holds about 60 cigars and I use a Cigar Oasis Ultra for the humidification. A lot of guys on here are big fans of the beads, but I don't have much background with them.
