Can I mix Boveda relative humidity percentages?
No. When they say, don’t try this at home, they’re referring to mixing Boveda RH levels or using Boveda with other humidification products, like gels, beads or PG solutions.
If you mix RH levels or products within the same humidor, you’ll create an inefficient and unsustainable environment and risk ruining your cigars. So within a humidor, stick with just one RH. Choose among 65%, 69%, 72% OR 75% RH for cigars.
