As you reach the bottom of your cannabis stash, you’ve probably noticed that your buds have gradually dried out. Preventing dry-out and keeping your cannabis at the ideal moisture level has a few benefits:
- The smoke/vapor is more palatable and a bit cooler
- Ground cannabis is easier to manipulate and roll into joints
- Better preserved flavor and potency
Naturally, the best way to prevent your cannabis from drying out is to take care of it in the first place, so let’s first go over some of the best preventative techniques for keeping your green fresher, longer.
Preventing Dry Cannabis
With these two easy precautions, you can extend the shelf life of your cannabis significantly.
Air-Tight, Away From Light
UV rays and oxygen are the enemies of fresh cannabis. Sure, sunlight and oxygen were this plant’s best friends before it came off the stalk, but once the cannabis is dried, cured, and packaged, you want to limit its exposure to the elements as much as possible.
For people buying cannabis in bulk (i.e. 1/4 oz. or more), it’s prudent to portion out your cannabis to keep each pack at peak freshness instead of cracking open the same jar every time, exposing those fresh nugs to the unforgiving composition of your local atmosphere. Think ahead and keep your greens fresh!
Glass Jars Over Plastic Bags
A flat of tiny, air-tight jars only costs about $10, and glass storage make a world of difference when it comes to keeping cannabis fresh. These don’t have to be anything fancier than a mason jar, but you can obviously find some pretty slick containers to house your stash.
A plastic bag will work in a pinch or if you have nothing else. Just be sure to remove as much air as possible from the bag before sealing. My preferred method is to roll the bag up from the bottom-like a rolled taco or crepe-toward the seal.
These simple techniques will keep your fresh bud fresher, but what if you get a dry bag of herb or you stumble across an old stash?
How to Re-Hydrate Dry Cannabis Buds
Re-hydrating your cannabis is a delicate process that requires patience, but not much more. Here are a few methods that I’ve used and have gathered from cannabis aficionados around the web.
Distilled Water Method
Distilled water is not that different from other water, but it is an extremely important ingredient when re-hydrating your cannabis. Distilled water, unlike tap water, has been evaporated and recollected to remove impurities. This chemically pure water is also used in some humidors.
Whether your cannabis came in a jar, Mylar bag, or a medicine bottle, this method will work about the same for each.
- Find a container with a lid that is large enough to fit your jar/bag/bottle of cannabis with a little room for your damp, folded paper towel.
- Wet a fresh paper towel with just enough distilled water to get it about 70% damp. Don’t get your paper towel too wet, because excess moisture can lead to mold.
- Place your open container of cannabis and your paper towel in your designated container and seal for 2-12 hours.
This process should slightly improve the relative humidity of your cannabis. This isn’t a silver bullet for dry buds, but it should help.
Note: This method is not a long-term solution—the more times the bud is re-hydrated, the more susceptible it is to mold. Be sure to replace your paper towel and clean your container between hydration attempts.
