How to Rehydrate Weed | 7 Methods for Rehydrating Weed

how to rehydrate weed

Dry, crumbly marijuana produces a harsh smoke that can irritate the throat and cause lung infections. In addition, it produces poor aroma and flavor.

So if you’ve found a bag of dry marijuana under your couch or in the back of your drawer, it’s time to rehydrate it before you smoke it.

But how do you rehydrate the grass to bring the buds back to life? There are many methods that can rehydrate your weed to help you get the most out of your bag of dried marijuana.

Why Rehydrate Marijuana?

Marijuana buds need a certain amount of humidity. When it begins to dry out, the terpenes and cannabinoids in the weed begin to break down, resulting in a loss of aroma and flavor. As a result, you no longer enjoy the aroma or experience the therapeutic benefits of the herb.

You must learn how to rehydrate the herb to preserve its flavor, aroma, and essential compounds.

However, these methods only apply to marijuana that has recently dried out. You cannot restore buds that dried up months ago because their terpene and cannabinoid content completely degrades over time.

How to rehydrate the grass?

There are many methods to restore the relative humidity of your cannabis buds. All methods aim to expose the marijuana flowers to moisture.

As grass is porous, it quickly absorbs moisture from the surrounding air and becomes soft with a flexible consistency.

Here are the different methods to restore the relative humidity of your cannabis.

Cannabis cellars

If you use dry marijuana regularly, it is best to invest in a high quality humidor. A cellar will help restore moisture to your buds. Additionally, humidors keep your cannabis at optimal humidity levels for months.

A typical humidor is a cedar-lined box fitted with a hygrometer which controls humidity. These humidors maintain the humidity level below 65%.

However, humidors maintain a relative humidity of 70%. Therefore, you should avoid them because excess moisture will do more harm than good.

To rehydrate your marijuana, place it in the cellar. Some humidifiers require a damp sponge or damp cloth. You must place them inside the box.

Next, calibrate the hygrometer and seal the cannabis inside the box for two hours. When you pull out the cannabis, your leaves should feel supple and soft.

Most humidifiers have different instructions. It would be best to read the instructions carefully before rehydrating marijuana.

Distilled water and airtight container

Another method to rehydrate your weed is to use distilled water and an airtight container to rehydrate your cannabis buds. It works like a makeshift humidor because you place the dry buds in a Tupperware container or mason jar with a tight lid.

The container should be of considerable size to hold the cannabis and a damp paper towel. First, soak the paper towel in distilled water.

Make sure it doesn’t drip, because you only need to moisten 75% of it. Excess moisture poses a risk of mold.

Next, place the cannabis buds and the paper towel in the container. Seal the container for two hours.

Only use distilled water to rehydrate weed as it is chemically pure and prevents marijuana contamination.

Fruit peel method

Using fruit peels is another great way to rehydrate your weed. Using fruit peels to rehydrate cannabis also introduces new flavors as it transfers terpenes. Therefore, you can use this method to improve the aroma and humidity of your dried marijuana.

Since fruit peels are naturally moist, they work as a preventative, short-term solution to rehydrate marijuana that has just started to dry out. However, this is not suitable for a long-term rehydration solution as it causes mold growth.

Start by peeling the fruit of your choice. More cannabis users prefer citrus peels. However, you can also use apple peels, grape peels, grapefruit peels, kiwi peels, citrus peels, and banana peels.

Place the fruit peel of your choice over the cannabis and seal them in an airtight plastic bag. Leave the cannabis and fruit peels in the airtight bag for two to three hours. Check for dry weed buds from time to time.

If the skin is drying out but the buds have not reached optimum moisture, you can remove the existing skin and replace it with fresh fruit peels.

You can also add herbs such as mint and rosemary to your sealed bag with dried herb to enhance the aroma of the buds.

lettuce leaf

Using lettuce is another popular way to rehydrate your weed. For example, you can use lettuce instead if you want to use the fruit peel method, but the peels don’t provide enough moisture to dry out the herb.

Lettuce leaves can rehydrate your cannabis because lettuce is mostly water. You should leave the lettuce in the airtight container or a ziplock bag for 12 hours.

Check the buds from time to time. Also, this method works well if you don’t want to introduce new flavors into the buds.


Using a slice of fresh bread to rehydrate dry cannabis buds works well. You can moisten a slice of bread and place it in an airtight container or glass jar.

Make sure the bread doesn’t come in contact with cannabis as you won’t like to smoke breadcrumbs.

This method of rehydrating cannabis works well, but you may need to repeat the process several times to get the best results.

Hot water

If you want to rehydrate your marijuana quickly, you can use a pan of hot water. Fruit peels, bread, and lettuce take hours, but the hot water method for rehydrating cannabis works in minutes.

However, this method can introduce too much moisture into your buds, so you need to be extremely careful. Here are the steps to hydrate grass using a pot of hot water.

  • Boil water.
  • Fill a saucepan with boiling water.
  • Place a cloth or paper towel over the pot and secure it carefully around the rim of the pot.
  • Place your marijuana buds on the washcloth and allow the cannabis to absorb the rising water vapor.
  • This porous plant absorbs vapors in 30 to 45 minutes.
  • Swirl the dry buds for a few minutes to ensure complete absorption.
  • Remove the cannabis from the cloth after 30 minutes if it has reached an optimal level of humidity.
  • Make sure the water vapors don’t overhydrate your weed.

Humidity package

When your cannabis dries out, you can restore the humidity by using a humidity control pack. The ideal humidity level for cannabis is 55-62%. You can rehydrate weed by purchasing a disposable humidity control pack to restore that moisture.

The exterior of the bag allows moisture to flow into the surrounding air. Because grass is porous, it quickly absorbs moisture and rehydrates.

If you like this method of rehydrating your weed, you might consider investing in a humidifier. Humidifiers are great accessories to make sure your cannabis buds stay fresh all the time.

Cannabis storage

If you’re concerned about the flavor and potency of your weed, you need to take some vital steps for proper storage.

First, you need to store marijuana away from pets and children. Beyond basic safety concerns, the right storage conditions can preserve your buds for longer.

Properly storing cannabis is vital if you want to preserve its aroma and flavor. You should always store your cannabis in an airtight jar or container, so that it does not lose moisture. Never place the sealed container in direct sunlight as cannabis loses its terpene and cannabinoid content.

Additionally, purchasing a humidor to store cannabis safely can prevent it from drying out. But if you want to use jars or containers to store cannabis, be sure to place them in a cool, dry place away from direct light so they don’t lose their moisture or texture.


If you open a bag of cannabis to find crumbly, dry weed, it’s time to rehydrate the marijuana using these different methods. But how do you rehydrate weed using the best method?

The best method of rehydrating weed is to purchase a humidor or humidifier, as this will prevent your cannabis from drying out in the future. Therefore, this long-term solution is ideal for preventing your cannabis from losing moisture.
