14 Best Weed Jars and Storage Containers for Weed in 2020
There are many options when it comes to storing your cannabis and keeping them potent and clean. Over the years, many cannabis growers or users have eventually learned the importance of storing weed the right way. The most common method among growers used to be storing weed in large plastic garbage bags, then putting them inside tubs or bins. But eventually, many growers have realized that their storage method isn’t exactly pertinent to their process. Which is why buds are extremely dry or weak when you get them. Many cannabis growers also longed to secure more reliable and sealed storage since some states mandate that the cannabis is kept in airtight and properly sealed jars or containers. Proper and appropriate weed storage method should help mitigate the evaporative loss of potency or drying out. In writing this post, we carry the goal of being able to provide you with great choices for weed jars and best storage containers for weed.
Ideal conditions for storing your weed
Best relative humidity (RH) for storing Cannabis
Relative humidity (RH) is the ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a prescribed temperature. The best relative humidity when it comes to storing cannabis is 55% to 62% RH. Studies have shown that cannabis will retain a higher terpene and cannabinoid content when this range of moisture is present for a prolonged period of time. Storing your cannabis in this RH range will surely retain a more robust flavor and a great high.
Ideal Temperatures for Storing Cannabis
Fungi and bacteria are very harmful not only to cannabis but to other plants as well. They promote the growth of mold and mildew and you would never want them on your cannabis. These molds grow at temperatures above 75 degrees and these harmful organisms can ruin your weed. That is why your cannabis needs to be stored at temperatures below 75 F or 24 C. Find and store them in an area where the temperature doesn’t fluctuate too much but remains around 65 F, or within ten degrees of 65 F at all times. This can be in areas such as a cupboard, drawer, or closet.
Previous conducted studies like “The Stability of Cannabis and its Preparations on Storage,” conducted by J.W. Fairbairn, J.A. Liebmann, and M.G. Rowan from the Pharmacology Department in the School of Pharmacy, University of London in 1975 found that that the best long-term weed storage method required keeping cannabis at room temperature in a dark and sealed container. It is ideal that you limit light exposure to weed that you intend to store. Light is actually considered to be the main factor that causes weed degradation. UV rays and intense light from many sources will break down cannabinoids. Therefore, choose a dark place to store your weed, a closet or drawer that doesn’t receive much light. Also, use a dark glass container when storing batches of your weed.

Some weed users and growers may not trust the use of vacuum sealing when it comes to storing weed. While some claim vacuum sealing, properly, with plastics which don’t contain BPA, is a great way to keep your bud fresh for a very long time. Others claim that plastic will ruin your weed and vacuum sealing will suck out your cannabinoids and damage your trichomes. Although, you can vacuum seal smaller individual doses, then store the individually sealed doses in a glass jar in a cool dry place so that it is still protected from temperature extremes and light exposure. You could even use a light-resistant plastic; however, you would need to be extremely careful to know the chemicals in your plastics because they can end up in your weed.
Weed storage Dos and Don’ts
- Remember to use an airtight container. A clear mason jar will be okay but remember to store it in a dark cupboard or cabinet.
- Keep your stored weed away from light.
- It is ideal to use containers made of materials with a neutral electrical charge. An example is a glass jar. This is to avoid static.
- Always keep different strains in separate containers to avoid mixing chemical compounds and aroma.
- Store filled containers in a cool and dry place. It should be at 70 degrees Fahrenheit and away from direct sunlight.
- Maintain an optimal range of 55% to 62% relative humidity (RH) in the storage container.
- Maintain relative humidity by using Boveda packs or VaporBeads.
- Store weed inside a chiller or freezer. This will result in dry, brittle, and tasteless weed.
- Keep weed in tin cans. These tin cans let in too much oxygen, which degrades THC over time.
- Store your weed without a humidity element.
- Keep weed in sandwich bags. The plastic has static that will pull off the trichomes, which contain the cannabinoids.
- Add fruit and mix them inside your weed jars. This will eventually create a too high RH and will result to molds in your buds.
- Use sandwich bags for storage, they generate a static charge and will result in your buds having an unpleasant plastic taste. Your weed will also be smelled since they are not airtight.
- Keep near heat and electricity sources. They will dry out your cannabis.
- Pre-grind and store for a very long period of time.
Things to Consider Before Buying a Weed Jar or Storage Container
There are a few things to consider before you invest in one of these products. Below are some aspects to keep in mind to ensure you invest in the right model.
An important thing to consider is the size of the weed jar or storage container. Sometimes these products might be too big or too small for your needs. Because of this, it’s ideal to closely look at the size. For instance, if you plan to have a lot of weed on hand and don’t want to transport it around, a larger jar or container might be best. On the other hand, if you want a jar or container to carry around with you in a bag, a smaller and more compact size might be ideal.
If it’s Airtight
You should also always make sure a weed jar or storage container is airtight. This will prevent moisture from seeping into it which can ultimately destroy the contents inside. Moisture can invite mold and harmful bacteria as well as reduce the flavor of your weed. Due to this, always make sure the jar has an airtight lid.
If it Protects Your Weed From Sunlight
Just as with moisture, sunlight can also be a problem. The UV rays emitted by the sun can cause your the color of your weed to fade which ends up leading to it being less flavorful. If you plan to keep your weed jar or container in a sunny spot, it’s a good idea to make sure it has a UV protection feature.
If it’s Smell-Proof
Another thing to consider is if the model is smell-proof. While a model might say it’s airtight, this doesn’t always mean it will help to prevent smells from escaping. Because of this, it’s important to ensure that the jar or container doesn’t leak smells when you use it.

Other Things to Keep in Mind
There are a few other things you’ll want to keep in mind before investing in a weed storage container or jar.
One is the price of the product. Depending on your needs, you’ll either want to invest in an affordable or expensive one. If this is your first time buying a weed container or weed jar, you might want to start out with a cheap one just to make sure it works for you. On the other hand, if this isn’t your first time, a more expensive one might be ideal.
Clean it Out
It’s always a good idea to make sure to clean your jar or container out often. This will not only help to prevent odors from forming, but can keep your weed fresh. Leftover particles inside might end up destroying the flavors of fresh weed. It can also be a hazard to your health as dangerous resin could coat the walls of the jar or container.
To clean out your storage container or jar, you can take a clean cloth or paper towel and wipe it out. This method is perfect if you don’t want to do a deep clean.
For a more intense clean, you can rinse the jar or container out under warm soapy water and then dry it out. Keep in mind though that this might not be possible for all container or jar types as it could ruin them. Because of this, make sure to check beforehand.
Be Careful with It
While these items are usually very durable, you still want to make sure to be careful with them. Too much bumping around could lead to scratches on its exterior ruining its appearance. It could also mean that the container or jar is more likely to fall out as it’s not being carefully watched. Due to this, just make sure to keep a close eye on it, or keep it in a special pocket or bag to help better protect it.
Don’t Put Extra Materials Inside It
As mentioned in the section in the beginning of this article, it’s a good idea to not put extra materials, like a plastic bag, inside of the product. This will not make it a bit harder for you to get your weed out, but could lead to static which can hurt the taste of the buds. It’s always important to put the weed inside of the containers or jars by itself.
Growing cannabis is not an easy task, and we know that. Which is why it is really important to store and keep them fresh in a good container. Finding a great stash jar or container might not be an easy task, especially for the beginners. However, we are pretty sure that after you read this post, you already have an idea which container is best for you. You have the option of choosing glass, metal or even plastic to store your weed. Storing your stash especially if you are a grower, using weed for medical purposes, or just a heavy stones, or someone who handles a large amount of weed is an important part of preserving the taste, aroma, and freshness of good cannabis. Therefore, invest in a good storage container to ensure you enjoy the full cannabis experience. Having a great permanent storage container also makes it more hygienic and easier for you to find your stash.

What’s the Best Pot? Containers Explained
Table of Contents
Which growing container works best for cannabis? What is it that makes some containers better than others?
The answers are contained in the roots of your cannabis plants. The idea behind choosing the right container is to pick one that is going to provide the best possible environment for your cannabis roots. Your roots are like the “heart” of your of your cannabis plant. They need to be healthy for your plant to get nutrients and grow.
What do marijuana roots want?
Happy cannabis roots want…
Moist at all times – roots die when they dry out! Good watering practices combined with a great growing medium will make sure your roots never dry out
Oxygen – your roots “breathe” oxygen, so one of the best things you can do for them is make sure they always have access to plenty of oxygen – more oxygen to the roots = faster growth
Nutrients – your roots “find” nutrients at the roots, and then deliver them to the rest of the plant, so making sure your plant has easy access to nutrients will help your plants thrive and make buds
pH Management – Some nutrients are sensitive to the pH of their environment. When exposed to the wrong pH, the molecular form of these nutrients actually changes. Nutrients in the wrong chemical form become unavailable to your plant roots. Exposing nutrients to the correct pH reverts them back to a form your roots can take in.
Bottled Cannabis Nutrients
Managing pH is especially important when using bottled nutrients.
Using bottled nutrients gets the nutrients to your plant faster (which equals faster growth), but it also means you are in charge of managing the pH.
These systems deliver nutrients directly to the plant roots in their simplest form, but there is no “middle man” between you and the plant roots, leaving you in charge.
So if you’re using bottle nutrients, make sure you manage your pH!
Amended & Composted Soil
When starting your cannabis grow with properly amended and composted soil, pH isn’t as important for you to manage. Instead of managing pH, you need to manage and care for the bacteria and microorganisms in the soil. In a proper composted soil setup, the microorganisms deliver nutrients to your roots in the right form. They become the “middle man.”
Types of Containers
There are many kinds of popular rowing containers for cannabis gardens…
Standard plant container with saucer
Here’s a breakdown of those different container options…
Standard plant container with saucer
This is a container with a hole at the bottom for drainage, plus a saucer to catch the water.
Tried and true method
Easy to find at any gardening store
Saucer captures runoff water for easy disposal
Smart pots (fabric containers)
More oxygen to the roots
Prevents plants from getting “root-bound” via “air-pruning” from the sides
Since growing medium dries out from the sides, smart pots make it difficult to overwater your plants, but that also means you will end up watering more often
Since smart pots dry out faster than regular cannabis containers, you should get double the size as your normally would, and it’s recommended your final size should be at least a 5-gallon container (anything smaller than that dries out in just a day or two!). So if you would normally get a 2-gallon container, you’d want to get a 5-gallon smart pot.
Need an extra large saucer or a tray to capture runoff water – smart pots don’t come with a saucer or tray and they seep out water from the sides
More oxygen to the roots
Helps prevent plants from getting “root-bound” via “air-pruning” from the sides
Since growing medium dries out from the sides, air pots make it difficult to overwater your plants, but that also means you will end up watering more often
Although water seeps out the sides when watering, air pots are tall and thin so you can use a regular size saucer for each container
Like a regular plant container except instead of having drainage holes out the bottom, they are located near the bottom on the sides
This leaves a small pool of water in the bottom of the container after watering
Need to water less often with hempy buckets, which is a great advantage when growing larger plants that drink a lot
Can sometimes lead to root or nutrient problems since stagnant water can sit at the bottom of the container and any nutrient buildup never gets rinsed out
How to Catch Water Runoff
The two most popular ways of capturing runoff water in small containers are…
Individual saucers for each container
Trays to catch runoff from several containers
Most regular plant containers come with a matching saucer. These are placed under the plant and catch the runoff water for each individual plant.
When using a container that lets air in through the sides (such as a smart pot or air pot), you will need a larger than normal saucer to capture all the runoff water, since water will be seeping down the sides of the container.
One of the problems with saucers is you usually remove them from under the plants to empty the runoff water (always remove runoff – never let it sit so it’s seeped back up into the growing medium!). This is easy with just a few plants, but can become a problem when growing with a lot of plants in a small space. It can be difficult to get to the saucers in the back after the grow space has been filled up with plants.
If you’re having trouble emptying out all your plant saucers, you may want to consider an alternative to regular saucers…
If you want to capture the water from a lot of plants in one space, I recommend using a tray set one a slight incline, so the part of the tray furthest away from you is raised slightly off the ground.. With even a tiny incline, the runoff water will pool at the front of the tray, and a wet vac can be used to capture all the water from the plants. This can be a lot easier than emptying saucers, depending on your setup.
As a bonus to using a tray, you won’t have to move your plants around as much, which results in better and faster growth. Plants don’t like being moved around if you can help it.
How to pick up the water from your tray?
- Wet/Dry vacuum
- Water transfer pump
I found the “Bucket Head” attachment at Home Depot which costs about $25 and can be attached to any standard bucket, turning it into an ultra-cheap wet/dry vacuum.
Which Size Container?
Final Size Container for Desired Plant Size – General guide
When choosing the size of your containers, you must think about the final size of your plant. Bigger plants will need bigger containers, while smaller plants grow best in a relatively small container. You need to match the size of your plant with the size of your container.
A general guide is to have up to 2 gallons per 12″ of height. This isn’t perfect, since plants often grow differently, and some plants are short and wide instead of tall, but this is a good rule of thumb.
So if your final (desired) plant size is…
2-3 gallon container
3-5 gallon container
6-8 gallon container
8-10 gallon container
12+ gallon container
Lots of different types of containers will work for growing cannabis as long as it has good drainage holes out the bottom
If you’re using a Smart Pot (fabric pot) or any container that lets in oxygen from the sides, you’ll get faster growth than a hard-sided container. However you will also need to water your plants more often since the soil will dry out more quickly.
Therefore it’s recommended to get twice the normal size if you get fabric pots so the soil doesn’t dry out as fast.
Get twice the normal size if the container lets oxygen in from the sides (like fabric pots and air pots)
Which size container should you start with? Start Small
To start, your plants will do best in a relatively small container. This helps prevent the chances of overwatering (since the container is so small) and since a small container dries out quickly, it will deliver more oxygen to the roots.
Many growers start their plants in a solo cup or a 1-gallon pot.
As mentioned earlier, some growers start their marijuana plants in their final container, which is usually larger than a 1-gallon pot. Starting in a big container isn’t as simple as starting with a small container, and can cause slower growth at first, but here’s you can take to get a seedling to grow quickly in a large container.
Once the leaves reach the edges of the solo cup it’s time to transfer to a larger container. These seedlings are getting close!
How to water seedlings or clones in a too-big container
When starting seedlings in a big container (bigger than 2-gallon), it’s important to slowly give just a little bit of water at a time until your seedling “grows into” its pot. This prevents overwatering, which slows down seedling growth.
By watering the right amount in the seedling stage, you can speed up growth significantly, especially during that first week or two.
For new seedlings you should give water in a small circle around the plant instead of saturating the whole container.
Don’t give water again until the top inch of potting mix is dry to the touch (which should be less than a few days if you did your job right). This makes sure your seedlings get a perfect mix of air and water so it grows as fast as possible.
Make sure to give water slowly in a small circle around seedlings until you get runoff water out the bottom of the container. This makes sure that water is getting to your plant’s roots but isn’t over-saturating the container.
After plant has started to “grow into” it’s container, the top inch of potting mix will start drying out quickly (less than a few days). At this point, you can start normal cannabis watering practices which means you saturate the whole growing medium until you get about 20% runoff water
How to water cannabis seedlings or clones in a too-big container
This is for when you’ve just planted your cannabis seeds or clones in a too-big container. By giving your young plants less water at a time following the steps below, you prevent overwatering which can slow down seedling or clone growth in a too-big container.
- Pour water slowly in a small circle around the base of the seedling (I first pour my water into a solo cup so that it’s easy to pour water around each plant).
- The circle should be
2 inches in every direction from the base of your seedling (or if your seedlings are bigger, about the width of the leaves).
Regular Watering Stage
Once your marijuana plants have established healthy root systems that can support the size of your container, you can start watering as normal.
- Once the top of the growing medium is drying out quickly, in less than than 2-3 days, you’re past the beginning stage.
- Switch to normal watering practices. This means that you are watering the entire container until you get 20% runoff every time. Then don’t water again until the top inch (up to your first knuckle) is starting to feel dry to the touch.
Important: Always wait until the top inch (up to your first knuckle) is starting to feel dry to the touch before watering your plant again. This prevents both overwatering and fungus gnats 🙂
Transplanting for faster growth
Transplanting means that you start your plants in a relatively small container, and then transplant the plants as needed so that their roots never run out of room.
Transplanting will provide your plants with faster growth if done right. This is because transplanting allows you to set up an environment where your roots are getting access to plenty of water and air. However, transplanting can stress your plants (and slow down growth) if not done properly. When transplanting, it’s important to carefully move plants so that their roots are not disrupted in any way. This means moving plants before they get root-bound, and creating a hole in the potting mix of their new container so the plants can be placed right in without disturbing the roots.
If you plan on starting your plants in a small solo cup and transplanting your plants to bigger containers as needed, take a look at this transplanting guide.
While transplanting makes it easier to give your young plants access to plenty of water and air, it can stress the plants if not done right, and it can also be too much work for some growers. So many growers start their plant in it’s final container.
When seedlings or clones are started in a large container, it can be difficult to get enough air to the roots until the plant is bigger and drinking a lot. Thisis because when the potting mix gets soaked, the seedling roots just won’t be able to drink it fast enough, and the roots will end up sitting in stagnant water with very little acces to oxygen. The growing medium has to dry out on it’s own, which can take a while, and your plant will be droopy and overwatered until the roots start getting access to air again.
Some growers start their seedlings or clones in a bigger pot, or even the final container they plan to use. While this can slow down growth of young seedlings, you can minimize this effect by watering young plants correctly when they’re started in a too-big container.
Here’s a very quick breakdown of some of the most common cannabis growing mediums for a hand-watered grow. This is not a comprehensive list, but should give you a place to start your research. Each of these different growing mediums have pros and cons.
Soilless (coco coir, perlite, vermiculite, etc)
Easy to find at any gardening store
You can start with nutrient-rich soil and transplant several times throughout the grow to give your plant what it needs after it’s used up all the nutrients in the soil in it’s current container. If you choose not to continue transplanting to give cannabis more nutrients, you will need to use cannabis nutrients to make sure plants are getting what they need
You will need to manage and adjust pH for a soil grow, especially if using bottled cannabis nutrients
Composted Soil – learn about composting your own soil
You will need to amend and compost your soil to use this method, which can take a lot of time, or buy amended and composted soil from a quality source
When done right, there’s no need for bottled nutrients or adjusting pH
Many growers claim that composted organic soil provides the best bud taste and smell
Soilless Potting Mix – (coco coir, perlite, vermiculite, etc)
Faster growth than growing in soil
Starting at the seedling stage, you will need to use cannabis nutrients made for hydro, since soilless mediums do not come with nutrients
Managing and adjusting pH is crucial to success in a soilless growing medium
Less likely to get pests or bugs
How much grow medium to get?
In the USA, a “3-gallon” plant container usually holds less than 3 gallons (same with 1-gallon, 2-gallon, 5-gallon, etc.). It’s a weird convention in the USA which means a direct conversion between listed gallons and gallons of soil (or conversion to liters) isn’t accurate. A “trade” gallon holds about 3/4 of a “real” gallon. This makes it easy to buy a lot of extra grow medium. To make things more confusing, in the USA not every 3-gallon pot actually holds the same amount of grow medium (it’s not totally standardized). Additionally, smaller companies often give the actual amount. Other factors change how much grow medium you need, including how high you fill the pot and how much it gets compacted. When in doubt, get the listed amount and you’ll always end up with enough or extra grow medium.
