Seasoning of two identical humidors continues. At around 34 hours into the study, the Pouches (in blue) are 67% RH and the HumiForm Mini (in red) is around 77% RH, about 10% higher.
Rough calculations show the cost-of-ownership for pouches being about $75 in the first year and then $40/year afterwards. This assumes a cost of around $6.50 per pouch, a vented holder costing around $23, and each pouch lasting 2 months as advertised. By comparison, the Mini costs $49.00 and lasts for two or more years on a single gallon of distilled water.
