Just found a baggie of bone-dry marijuana in the back of your closet or under a cushion on your couch? Don’t throw it away. Learn how to rehydrate weed to bring those buds back from the dead.
First off, avoid smoking dry, crumbly-to-the-touch marijuana. It’s harsh on your throat and lungs. It tastes terrible. It’s difficult — if not impossible — to roll into joints and blunts. It burns fast and unevenly. And it doesn’t cause a decent high.
In fact, overdried cannabis might not cause any high at all. Major bummer! But fret not, dear cannabis compadre. There is hope.
In this article, the ganja experts at Honest Marijuana give you simple DIY tips on how to rehydrate weed and get the most out of crumbly bits at the bottom of your stash.
Why You Need To Know How To Rehydrate Weed
It doesn’t matter whether you’re dealing with high-quality beasters, run-of-the-mill mids, or bottom-of-the-barrel regs, weed will dry out eventually. That’s just how nature works.
But, all too often, something you do — or something someone else did — will accelerate that process and make your buds dry out faster than normal.
That’s why it’s vital to know how to rehydrate weed: it will help you preserve a large portion of your stash and give you a better chance of using it all up.
Here are the main variables that make knowing how to rehydrate weed an essential skill for every cannaenthusiast.
Overdried To Begin With
The drying and curing process is as much art as it is science. Knowing when to move from one stage to the next is tricky business.
If, after harvest, the grower dries the plant matter too much before curing, the buds have a tendency to become crumbly and harsh much faster.
And, unfortunately, there’s no way you can tell what’s going on inside the cannabis just by looking at it.
Drying marijuana removes moisture from the inside out. So you may purchase the most beautiful, gooey, trichome-rich flower you can find, but if it’s overdried, the bud doesn’t have enough moisture left inside to maintain that appearance for long.
If you don’t consume it quick enough, it will dry out.
One of the worst things you can do to your marijuana is store it poorly. Keeping your buds in the wrong container allows water within the plant matter to “seep out” into the surrounding air.
Eventually, the once-healthy cannabis will dry out altogether and turn into the crumbly, harsh, foul-tasting powder that won’t get you anywhere near high.
To extend the shelf life of your cannabis — and to preserve the water content within the plant — store it in an airtight container away from direct sunlight.
A mason jar with a lid or a Tupperware container is ideal for this job. Avoid storing your ganja in a plastic bag.
Too Much Decarboxylation
If you’re smoking weed, decarboxylation occurs instantaneously when you apply an open flame to the plant matter.
But if you want to cook some edibles or whip up a concentrate, you need to “activate” the THC and CBD by decarboxylating at low temperatures (usually in an oven) so you don’t completely destroy the weed.
The problem is you can over-decarboxylate your cannabis if you leave it under heat too long or if you apply too much heat to it too quickly.
Should this happen, it’s great to know how to rehydrate weed so you can rescue and recover your stash from the brink of destruction.
The Theory Behind Rehydrating Weed
The theory behind rehydrating weed comes down to relative humidity. When you place a dry object and a “wet” object in a sealed container, you create a microclimate.
Within that microclimate — and because of the way molecules behave (Science, y’all!) — water moves from high concentration zones to low concentration zones until the system evens out.
So, for example, if you put a dry object with zero molecules of moisture in a sealed container next to an object with four molecules of moisture, the dry object will “steal” two molecules of moisture from the wet object.
Keep in mind that this is an extremely over-simplified explanation, but it gives you a basic idea of the science behind rehydrating your weed.
Before we get to the actual methods of rehydration, there is one variable you should always take into account: water type.
Always Use Distilled Water
Distilled water is water (duh!) that has evaporated, condensed, and passed through a filter. The process of distillation removes impurities, minerals, and chemicals that destroy your weed.
That’s why it’s crucial to always use distilled water when rehydrating your weed regardless of the method you choose.
With that in mind, let’s get to the meat — or moisture — of this article.
DIY Hacks For How To Rehydrate Weed
1) Moist Bread
One of the simplest ways to rehydrate weed is to moisten — don’t soak — a piece of bread.
Place the bread and the dry weed in an airtight container for an hour or two to allow the moisture to distribute itself. Check the bread and repeat the whole process if necessary.
When your marijuana is sufficiently rehydrated, remove the bread, reseal the lid, and store it in a cool, dark place (e.g., a cabinet or closet) away from direct sunlight.
2) Fruit Peel
Another great way to rehydrate your worn-out cannabis buds is to place them in an airtight container with your choice of fruit peel.
Lemon and lime are the two most common, but other choices include:
Using fruit to rehydrate your marijuana has the added benefit of introducing new flavors into the mix — via the transfer of terpenes and essential oils — that might not have been there before.
If you’re not too keen on fruit flavors, try fresh herbs like mint, cilantro, rose, rosemary, or thyme.
Any fresh plant matter sealed in an airtight container will transfer its moisture to the dry marijuana, rehydrate said weed, and add a zing of flavor in the process.
4) Terra Cotta Disc
Cooks use terra cotta discs to keep their brown sugar moist and pliable. You can use the same concept to rehydrate your weed.
Soak a terra cotta disc — available pretty much everywhere — in warm water for 30 minutes. Place the moist disc in an airtight container along with your dry marijuana and watch the magic happen.
5) DIY Rehydration Chamber
Here’s a simple way to create your own rehydration chamber.
- Boil water in a pot.
- Spread dry ganja evenly on a cookie sheet.
- Place the cookie sheet on the top shelf in your oven (oven OFF).
- Place the pot of boiling water on the bottom shelf in your oven.
- Close the oven door.
- Check every 15 minutes.
With this method, the steam from the boiling water rises to the top of the oven, cools, and falls onto the dry buds (Science, y’all!).
6) Humidity Control Pack
The ideal humidity (water content of the air) for marijuana is 55 to 62 percent.
You can maintain or restore this relative humidity — and rehydrate your weed in the process — by purchasing and using a self-regulating, disposable humidity control pack.
The exterior of the pack allows the moisture within to flow slowly out into the air around it. The dry weed absorbs that moisture and rehydrates.
Watch Out For Mold
Introducing moisture back into your dehydrated weed with one of the methods above is a great way to revive “expired” marijuana.
But it does come with some complications. Chief amongst those complications is that, while rehydrating does reinvigorate your weed, it also increases the chance that mold will form.
And you don’t want that.
Moldy weed can even cause some rather serious health problems, so it’s important to inspect your rehydrated marijuana before you smoke it.
The two most common types of marijuana mold are:
- Botrytis cinerea (a.k.a. bud rot)
Bud rot is the least dangerous of the two, although it can still cause serious health problems, like lung damage.
Inhaling aspergillus, on the other hand, can cause infection, aspergilloma (ranging from cough to severe fatigue to bleeding airway), and even invasive pulmonary aspergillosis, which can be fatal if not treated properly.
Avoid both of these molds at all costs.

Avoid The Need To Rehydrate
You can avoid the need to rehydrate by purchasing your marijuana from the best sources possible.
Honest Marijuana, for example, has perfected the drying and curing process and packages and seals their marijuana flowers in airtight, light-proof, humidity-proof canisters that keep the buds at just the right conditions to prevent them from overdrying too quickly.
So, as long as you don’t leave your cannabis uncovered in the sun for days at a time, you can rest assured that you’ll have the freshest, moistest (yes, moistest), most delicious ganja on the planet.
