    Mason Jar-Cheap and Effective Weed Curing Method

    Technically, as long as it dried, you can smoke uncured weed. But, smoking uncured weed, to be diplomatic, is quite underwhelming. Because curing not being absolutely necessary to smoke weed, curing cannabis is one of the most underappreciated; yet essential steps in getting your weed ready for smoking.

    Curing 101-Mason Jar Curing Method

    This article is a how-to guide on curing weed by using a Mason or other type of airtight jar or container. The canning jar curing method is the most popular and proven method for curing bud. It is also among the easiest and cheapest ways to cure. First, though, I will go into the basics of drying before I explain the glass jar curing method.

    Drying Process

    Properly drying cannabis is essential to preserve its trichomes, terpenoids, and more. The weed drying process is an article on its own as there are several methods commonly used to dry bud. So, I will only briefly go over the three most common cannabis drying methods, which are the paper bag drying method, upside-down hanging method, and drying rack method.

    • Brown Paper Bag Drying Method -I wrote an extensive article on this method, which can be accessed here. This method is, as you hopefully guessed, is simply drying weed in a paper bag (Cardboard box also). For the home grower, with limited space, or those valuing privacy, it is an excellent solution.
    • Hanging Buds Upside Down -You hang your plants upside to dry, which is the preferred way for many growers. However, it requires a drying room or grow tent. Additionally, it also not as concealable as when using paper bags.
    • Drying Rack – A commercial drying rack is a preferred choice for commercial growers. A drying rack has advantages or organization, and less risk of mold and other contaminations than with other ways to dry. The disadvantages are mostly the same as with the “Hanging Buds Upside Down” method,” of more space being needed, and privacy concerns. A drying rack can also be quite costly.

    Quick Drying Methods -Quick-drying buds are not recommended. But, it can be done if you just can’t wait for your bud to be dried and cured. Some of the common methods for quickly drying buds are the microwave, oven, and food dehydrator.

    Notes on Drying Weed

    If your buds are too moist you will have mold problems. So, when drying weed, you’ll have to be patient. Most likely within five to 15 days, you’ll be able to get dry bud. On the other hand, buds that are too dry will burn far too fast when smoked.

    The number of days and the moisture levels are just rough guidelines, and should never be solely relied upon. Instead, you should do a simple test of simply taking off a small branch and bend it. If the branch breaks they are ready to be cured, and if it bends you will need to be a bit more patient and let them dry more.

    Can You Smoke Uncured Weed?

    As uncured marijuana is smokeable, curing cannabis buds isn’t absolutely necessary. However, uncured weed buds will leave you with an overall unsatisfying smoking experience

    Why You Should Cure Weed?

    Below are a few reasons why curing weed is highly recommended.

    Better Smoking Experience – Uncured buds have bacteria that when smoked give off an unpleasant, nasty taste. Curing eliminates this bacteria, which means an overall smoother smoking experience.

    Terpene Preservation -Terpenes will be more likely to be preserved when a marijuana bud is properly cured.

    Potency- Uncured buds are less potent.

    Preservation – Properly cured buds increases how long buds can be stored. Per Weed Maps, if buds are cured and stored correctly your stash will be more likely to be protected from mold and can even last up to two years with little or no change in the THC% or the flavor.

    What Is The Optimum Curing Environment?

    The Mason Jar curing method and all methods of curing should have the following environmental conditions inside the jar.

    Room Temperature – 70 degrees Fahrenheit

    Relative Humidity -60 to 65%

    Light -The room should be dark or an opaque jar can be used

    How Do You Keep The Humidity Levels Between 60 to 65%?

    A humidity pack is a cheap method for controlling the relative humidity in your curing jar. The typical humidity pack is made from pure water and salt and lasts up to two to four months. (They’ll last this long when they are placed into an airtight jar or other containers) All you do is put them in the jar and let them do their job and when they become stiff you take it out and put in a fresh one.

    The Boveda Pack

    The Boveda Packs are the most popular humidity packs and depending upon how much weed is being cured, they are quite cheap. What is especially impressive about the Boveda pack is that you are able to set the RPH between 58 to 68 relative humidity.

    Orange Peel

    An orange peel also can surprisingly control humidity in your curing jar. All you do is place an orange peel in the jar. Personally, I would just stick to Boveda Packs.

    Mason Jar Cannabis Curing Method

    Please, note, even though a Mason or canning jar is referenced in this method, almost any airtight container will work.

    TIP-Buy an opaque jar if you cannot place your curing cannabis in a dark area.

    Equipment Needed

    Glass Mason Jar -A simple mason or a sealable glass jar is the most common glass container-

    Humidity Packs -They will help make sure that the jar is kept at the optimum RH levels.

    Hygrometer -Used for the daily measurement of RH inside the jar.

    Curing Steps

    1. Pack It-Place trimmed and dried cannabis flower into the container around 2/3rds full.
    2. Hygrometer-Be sure to put a hygrometer and a humidity pack or orange peel into each jar.
    3. Store It-Store the curing jar in a pitch-black, darkroom. Alternatively, if you do not have any dark areas available, an opaque jar, or a specialty curing container will do the trick.
    4. Check It and Burp It-Periodically check your weed for the correct humidity and temperature and also remember to burp the jars. (Look below for a description)
    5. Wait For It To Be Cured– Per Leafly, two to four weeks in the bare minimum. And some growers will cure their buds for up to a month. Additionally, some cannabis strains could benefit from curing for a half year or even more.

    What in the Heck is Burping?

    Burping allows moisture and oxygen to escape from the curing jar. Burping both removes potentially harmful gas pressure from the jar and also moisture.

    How To Burp Weed

    If you can take a lid off of a jar and put it back (and give it a light shake) you can burp cannabis. Alternatively, with a bit more work, you can pour your buds out of the jar onto a paper towel to air them out, and after a few minutes, put them back into the jar.

    How Long And When Should I Burp The Buds?

    This rule varies between growers. Newbies though should stick to these industry-standard rules until they feel confident to experiment. The rule of thumb is that the jars should be “burped” or opened at least once a day for at least ten seconds.

    Time May Vary

    The time and how much to burp will vary greatly. But, factors such as the RH levels could mean that you will need to either open the lid for between 30 minutes daily. Some growers state that burping is only needed on a weekly or bi-weekly basis. On the extreme, one book published in 2001 said (they were using a can) you should remove the lid for six hours a day!

    How Long To Cure?

    The amount of time to burp depends greatly upon who you ask. Some growers, treat bud curing like a fine wine in that they believe the longer the cure the better the buds will be. However, the “fine wine theory” for bud curing is not proven. If you use the once per day for around ten seconds curing method, your weed should be ready to be smoke in around three weeks to a month.

    Final Thoughts

    The curing process is a skill that will take time. But, this skill is well worth learning. As I’ve stated much time in my previous articles, first learn the basic or industry standards to cure weed. Then, after you’ve been successful you can try to experiment with a few jars. For example, try to cure your weed for a long time than a month. Try the six-hour, burping method, etc. Eventually, with time you will be able to find a way to cure that works well for you.


    What Is The Best Hygrometer For Curing Bud?

    As stated, curing is not necessarily mandatory. Curing though will allow your crops to reach their fullest potential. If not done correctly, curing can ruin a successful grow. For example, too high humidity can cause mold. Luckily, though curing buds though isn’t that complicated. To be successful you will however have to ensure that your curing container is at the correct temperature.

    The humidity level and temperature are measured by a hygrometer, as such, they are mandatory for curing. The good news is that perfectly acceptable one are quite cheap. The only thing that you need to remember is that you should have a hygrometer for every weed curing container. Below is a highly rated hygrometer that can be purchased in bulk.

    Individual Hygrometer

    An individual hygrometer needs to be small enough to be able to be fit in a curing container. This isn’t a problem though as, on Amazon, and elsewhere there are numerous mini-hygrometers available that are quite cheap. As an example, these highly-rated hygrometers come in a pack of 12.

    A potential problem with these is that there are several complaints that the humidity and temperature are not accurate. One reviewer stated that each separate hygrometer had different readings. However, they have very high overall ratings and are quite cheap. So, these and other similar ones should be suitable for the hobbyist or small-time grower.

    Built In Hygrometer Containers

    There are several airtight containers are specifically designed and manufactured for curing. One of the most popular is the CRYPT

    CRYPT-A Metal Container Specifically Designed For Curing Pot

    CRYPT - Cannister for humidity controlled storage with built in Hygrometer – Airtight Jar & Water Proof Keeps Herbs Fresh (1.5L)

    The CRYPT is a metal container, resembling a pressure cooker that is specifically designed for curing weed. They come in the following sizes:

    • 20 oz or 600 Ml
    • 32 oz or 950 ML
    • 42 oz or 1.25 L
    • 50 oz or 1.5 L

    Over glass jars, the CRYPT has the advantage of durability (it will not break as easily as glass), is lightproof, and has a built-in hygrometer.

    At first glance, the CRYPT, when compared to a plain Mason Jar, and other similar humidity control curing containers seem quite expensive. However, if your average hobbyist growers these containers may not be that expensive.

    Storing Cannabis

    The glass jar also provides a convenient way to store weed, and a glass jar is a preferred way to store cannabis. The reason is that over time a plastic bag, metal container, and even a tobacco humidor will negatively affect the cannabis flower’s taste.
