Overall Winner: Anchor Hocking 2.5 Gallon Montana Glass Jar
The large size combined with the low price point make it the best value in large curing containers.
This jar is made of thick glass and has a large capacity that can hold up to about a pound of weed. We have been using these jars to cure weed for years and are very satisfied.
Pros:
Low price:
These 2.5 gallon Montana Jars used to be sold on Amazon for $25-$30 in the 2.5 gallon size, but recently the price has has jumped considerably. At over $40 there’s not as much value but its still a great jar for that price.
The 1.5 gallon Montana Jar or the 2 gallon Montana jar are a good alternative to the 2.5 gallon jar when the price spikes. I prefer the 2.5 because the large size and super-wide mouth makes it easy to gently rustle the buds during curing. But the 1.5 gallon or 2 gallon jars work just as well and are worth considering if the 2.5 prices are crazy.
Large size: The 2.5 gallon glass jar holds about 10-16 oz. (can vary depending on the size and density of your buds) of weed when filled about 3/4 full for curing. For long term storage you can fill right to the top and easily get more than a pound in here. It’s perfect for home growers running a small grow tent or grow room with a few plants.
Super wide mouth: You can easily fit your hand in, and the large mouth lets you mix up your buds to avoid wet spots.
Easy to clean: The glass jar is easy to reach into to scrub, and the lid lets you unscrew the knob and separate the rubber seal for easy cleaning
All of the Anchor Hocking Jars have a rubber gasket seal. It’s tight enough for curing but not as airtight as a mason jar.
Cons:
Lid seal: The lid seal is fairly tight but not as perfectly airtight as glass mason jars. The Anchor Hocking jar’s lid doesn’t leak odors, but the inside rubber seal isn’t completely tight either. It’s perfect for curing and short- to mid-term bud storage, but for storage beyond a few months it’s better to get cannabis curing jars with an airtight seal.
Not light-proof: Exposure to UV light can impact THC, so you’ll want to keep clear glass jars out of direct sunlight and away from your grow lights. Storing in a cool, dark place is best.
The first couple of times when we bought the 2.5 gallon Montana Jars on Amazon the prices were below $30 range. Most recently they were more like $50 and up to $80, with that price changing every day for a week.
If you can find one under $40 then buy it right away. Above the $50 price point they’re just not worth it, you’re much better going with the more durable stainless steel CVault if you’re looking to spend that much on large curing containers.
When you’re choosing a curing jar for weed, you want to balance cost-effectiveness with both performance and ease of use.
The classic half-gallon mason jar has an airtight seal, moderate storage capacity, and a wide enough mouth to allow you to easily insert and remove very large colas. They’re pretty cheap and available at many hardware and craft stores which is nice for people who don’t live near a grow shop.
Note: Online prices for large sized mason jars are a bit more than the local store prices in my area – presumably because they’re a pain to ship. You can get a pretty decent price on large mason jars for curing if you buy bulk — sometimes.
You can buy half gallon mason jars in a 2-pack, 3-pack, a 6-pack, or a 12-pack. The prices have been jumping around lately on Amazon, and sometimes it’s cheaper to buy multiple smaller packs than to buy the bigger pack. So look around there for deals.
Each of these mason jars holds about 2-3 ounces of curing weed.
Pros:
Low price: If you can find them locally they’re very cheap. Not too bad when ordered online in bulk, most of the time. But avoid individual bottles on Amazon, they go as high as $25 apiece which is a ripoff.
Airtight seal: Mason jars with 2-piece lids are very air tight, great for long-term storage.
High availability: Can be found in most hardware stores, Walmarts, and places with a canning section.
Cons:
Size: Since you only fill the jars 3/4 of the way when curing, for even a small grow with a few plants you will need a bunch of these jars. You can fit 2-3 oz per jar, depending on bud density and size. Curing in mason jars is best when you need containers for a few plants of different strains, so you get a few jars of each. But for larger plants you’re better off with one of the large curing jars or a CVault.
Half gallon mason jars are a bit small for curing weed so you’ll need to burp a bunch of them. They’re best for small grows.
Many jars to burp: Since you have to burp your jars often when curing, having to open a bunch of little jars and stir up the buds is a lot more work than to open one very large jar like the 2.5 gallon sizes. It’s also harder to stir up the buds at the bottom if they’re sticking together than it is in larger containers. Consider a Burp Lids curing kit which eliminates burping and uses a pump to create a vacuum in your curing jars.
Not light-proof: Exposure to UV light can impact THC, so you’ll want to keep clear glass cannabis curing jars out of direct sunlight and away from your grow lights. Storing in a cool, dark place is best.
Hard to clean: Thin hands will easily fit inside to scrub them. Thicker hands can get stuck. If you do get stuck, apply soapy water to your wrist as you twist the jar off.
Check these links for the cheapest 1/2 gallon jar options we’ve found on Amazon. Sometimes they’re cheaper when you don’t buy from the Ball store. And good luck finding amber mason jars in the half gallon size, they’re often sold out.
You can also find 1 gallon jars with tight-sealing plastic lids. The plastic lid isn’t ideal, but if you’re looking for the best large curing container on a budget then these work well.
CVault makes midsize and large curing containers that are air-tight and easy to access. The CVault 21 Liter Stainless Steel Humidity Container ($150-$200) is an air-tight storage container that is perfect for curing weed in larger amounts.
The 8 liter CVault is a good size for most small tent grows (4×4 or 5×5). It holds about a pound of weed.
CVaults cost a bit more than the glass jars above for comparable sizes, but they will last a long time and won’t break if you drop them. The tight seal and solid construction make them the best large curing containers you can buy.
Watch our for price fluctuations. It comes in a few sizes:
Airtight seal: The 3 locking clasps on the lid ensure no odor or moisture escapes, so they’re great for stinky buds and for long-term storage after curing.
Large lid opening: Unlike glass jars, the CVault lids are as wide as the container. This makes it easy to stir your buds up when you burp them.
Built-in storage for humidity packs: The lid contains an area designed to hold humidity packs such as Boveda 62% Humidity Control packs, making it easy to re-hydate overly dried buds. This is also helpful for very long-term storage to ensure your buds don’t dry out and become powder when you grind them.
Durable: No need to worry about pulling shards of broken glass out of your buds after you accidentally drop your glass jar.
Stackable: If you’re curing large amounts of weed, you can’t stack large curing jars made of glass. But you can stack these suckers.
The 4 liter CVault is kind of small for curing but it’s good for long-term weed storage.
Cons:
Cost: These are made of stainless steel and are much more expensive than similarly-sized glass cannabis curing jar options. A 2-liter CVault container is comparable in size to the half-gallon glass mason jars, at more than 10x the price. But you’re paying for quality and functionality.
Worst weed curing containers
Sometimes growers just don’t have the option of using glass jars or stainless storage containers. If you absolutely must cure in plastic, you could use:
Tupperware containers or large storage totes: Can impart a “plastic” smell which affects taste, but are easily available and cheap. Their large capacity, low price, and easy availability makes this an option some growers choose. But certainly not ideal
Turkey Bags: Inexpensive and can hold a large quantity. Smell tends to escape the thin bag though.
Freezer bags: For the “use what you have on-hand” grower, these are an easy choice. Smell can seep through, and many times they don’t completely seal.
5 gallon buckets with lids: Look for food-grade if you go this route. Using a simple Home Depot orange bucket will impart a plastic taste.
The CVault 2 pack is good if you’re growing a few small plants of different strains.
Summary
While have had lots of success using the 2.5 gallon Anchor Hocking Jars are the best jars to cure weed, we certainly would prefer the CVault containers if price wasn’t an option.
When choosing a jar, look for an air-tight seal, easy access opening, and durability. Avoid using lots of small jars unless you really enjoy spending extra time monitoring them.
