I have been using Boveda Humidity packs for a while now, and I love them. They keep your herb at a constant humidity level. This keeps your stash fresh, whether you live in a low humidity condition or high humidity. They last a pretty long time, seem to be durable, and are a good value.
It’s winter here in Illinois, and humidity in the house ranges from 20% to 50%; my marijuana dries out very fast, even in airtight jars. I don’t have that problem anymore, thanks to these Boveda’s. They also work for high humidity, like in Florida and other humid places. It is like magic, using some types of salts, but it works equally well for humidity leveling.
They come in various sizes and humidity levels; I use 62% for my cannabis, but I know of other people who use 58%. They are a must-have for your humidor, storing cigar and pipe tobacco, which use a higher humidity level. I also use 62% for my cigarette tobacco, which also dries out in these dry winter conditions. Just pop one in the bag, problem solved. They also are used to keep the humidity right for your musical instruments, such as expensive guitars, violins, etc. Just pop one in the case, and your all set.
Keep them sealed until you are ready to use them; however, once opened, you can keep them in an airtight container, and they will keep. A good solution is when your jar or container gets empty, put them in (as long as it’s airtight) and they will last a long time for you. you can also use airtight plastic bags, the sealable type. Also useful for CBD flower. If you are a grower, Boveda humidity packs are a must-have for your drying and curing process. You can tell they are used up when they get hard and stiff.
