Since I first published this Boveda for Cannabis review in December, 2020, I have received countless thank you emails form people who who were just thrilled to learn about these little miracle packets.  That's because 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.  

Of course these are moisture control packs, but they can also work to add moisture back to cannabis that is too dry.  

That's right, 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. 

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!

How Does Boveda for Cannabis 2-Way Humidity Control Packs Work?  

It's not magic and it is all natural.  

Inside the packets is a mixture of water and natural salts, encased in a breathable reverse osmosis membrane (how's that for a scientific jargon?).  The bottom line is, it works to create an ambient relative humidity in the container in which the packet resides.

Boveda packets are used for far more than cannabis, and likewise are available in different relative humidity (RH) levels.

What is the Best Boveda for Cannabis? 

I like to use the 62% RH (relative humidity) for freshly harvested cannabis.  But the 58% RH packs also work well.  It's really a personal preference which you chose.

When it comes to the best size of Boveda for cannabis, that is completely dependent on you and your stash.  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.

How to Use Boveda 2-Way Humidity Control Packs

Using Boveda packs is as simple as putting them in a container, usually a glass jar, with your weed. 

Outdoor growers who grow a single crop a year, and likewise need to store that stash for the upcoming year, might also want to consider stainless steel Cannavault containers, which come with a built-in space to put your Boveda packets, for the ultimate in optimal storage.

Regardless of what you store your marijuana in, know that there is no limit to how many Boveda packs you can use (which is why if I have extra, I just stick them in one of my jars).  You don't need a bunch in one jar, but it as good a place to store them as anywhere.

What you do not want to do is to leave the packets out exposed to air for extended periods, as they will be attempting to control the humidity in your house and they will wear out quickly.  But in a closed container, they can last a year or two or even longer.

How to Tell When Your 2-Way Humidity Packs Are Wearing Out

When you buy fresh Boveda packs, it will feel like the packs are filled with gel when you squeeze them.  If you squeeze your pack and the contents feel hard, dry, or crumbly, you'll know that pack has lived out its use and it is time to replace it.

  • I totally agree with Cheri. I am 70 years young and have been useing Bovida for several years. I use the 62% packet and have never had bud rot or too dry of product. You can also rehydrate your packets by putting them in a ziplock with a damp paper towel. Great product!

  • These are fantastic and the price is great. I use the 62% as living in the dry desert southwest our rh is low. It is 30% today and that is after a 3″ snow. I accidentally over dried my last harvest and added the Boveda post cure. The cannabis is wonderful and smells like strawberry jam, so I know Boveda did help save it. I also put a packet in a jar of dried up dispensary weed we had and was amazed that it seemed to refresh it. At that point I am sure the THC had degraded quite a bit but we still got a decent smoke from it.

    My question is this: when they turn crunchy and hard in the jar is that time to toss it? I have only been using these for about three months.

    • Exactly. Crunchy and hard tells you it has lived out its usefulness. How long they last will have a lot to do with the humidity where you are and likewise how hard they have to work to keep it balanced. I have had some for years, but I live near the ocean.
