Scientifically engineered to maintain a precise relative humidity in an enclosed space, Boveda humidity control packs will never humidify beyond the RH on the pack, so there’s no such thing as “too much”. You want to think in terms of using at least the minimum because the more you use, the more efficient Boveda works and the longer they last. You’ll know it’s time to replace when the entire Boveda pack becomes solid.
Simply place the correct number of Boveda inside your container to maintain a precise relative humidity. Each Boveda consists of a specially prepared saturated solution of pure water and natural salt. This saturated solution is contained within a water-vapor permeable “reverse osmosis” membrane. Within a closed container Boveda maintains a predetermined level of (RH) by releasing or absorbing purified water-vapor, as needed, through the membrane.
Boveda provides the cleanest and most purified humidity of all other products available on the market today.
Been using these over a year. They work perfect. Last months. Their containers are a steal also. High quality stainless. Will not be sorry.

Have multiple strains? - One small envelope in a 4, 6 or 8 oz canning jar keeps [dry material] perfect that would otherwise be long dry. Also I pre-grind small amounts of 6 strains, store in little .85oz glass jars, six jars with loose lids in a small 4x6 plastic container with two small envelopes -- perfect. Lasts for months.
I bought these 62% RH Boveda packs. I have the 4gr, 8gr and 60 gr packs. You can use it in simple glass jars and not only in official CVault products. 62% RH maybe is too much, I prefer 58% RH but boveda has only 49 or 62 (or more) RH packs. Boveda is accurate within +/- 2% of the RH level printed on the pack. It will last an amount of time that depends on how many times you will open your 'humidor', and from external moisture level. The contents of every bag is liquid, you'll have to replace the bag when the content will be solid.
Carefully choose which pack buy depending on how much medical herbs you should keep:
4 gram: 7-14 gr.
8 gram: 14-28 gr.
60 gram: 112-450 gr.
You receive 1 8-gram humidity pack for $3.25
Boveda are individullay wrapped in clear plastic to give them a two year shelf life.
Boveda Packs should last 60-90 days each. Once the packet solidifies, your Boveda will need to be replaced.
