Whether you grew it yourself or you buy from a dispensary, you can protect your investment in your cannabis stash by putting small Boveda packs in your storage jars.
These little packets work like magic and are a must for long-term cannabis storage. Put a packet in your jar and you have turned that jar into a small humidor with automatic 2-way humidity control. Meaning regardless of whether the climate where you live is too dry or too moist, inside your jar of marijuana, you will always have perfectly controlled humidity.
I like to use the 62% for freshly harvested cannabis, but the 58% RH (relative humidity) packs also work well. It's really a personal preference which you chose. The packs are available in a variety of sizes from about the size of a sugar packet -- perfect for small personal stashes -- all the way up to HUGE packets meant for storing large commercial grows.
Boveda packs are inexpensive and last a LONG time (ours from last season are still going strong). It's almost silly NOT to invest in a few Boveda packs, even if you do nothing else when it comes to cannabis storage.
If you grow your own or buy in larger quantities to save money, you will DEFINITELY want to get some Boveda as it will keep your cannabis fresh and perfectly cured, even after LONG TERM storage. I recently smoked some 3 year old cannabis that was properly stored in a light proof container with Boveda, it tasted as good as it did when first cured.
If you are tired of dry crumbly weed, or if you are worried about overly moist cannabis and mold growth, these are worries of the past once Boveda enters your life.
