Boveda provides 2-way Humidity control for your medicine. Perfect for any air-tight storage containers or jars. Every Boveda RH is accurate to +/- 1% in an air tight environment. It's common that the actual RH of your humidor/container will stabilize up to 5 points lower than the Boveda RH you're using, due to container quality and ambient dryness. That's why we offer Boveda in two different RH levels- 58% and 62%. So you can use the RH that achieves the humidity you and your extracts prefer.
