will cannabis seeds go bad in an air tight container

Does weed go bad? Myth and reality

Who hasn’t found a weed bag that you thought was lost? This happens sometimes when searching through your wardrobe or drawers and you don’t know if consuming it would be dangerous or not. For this reason, it’s important to know when marijuana is apt for consumption to avoid future problems. But, does weed go bad?

After harvesting, the first step is to dry it. If carried out in perfect conditions, in a fresh place and with humidity levels ranging at around 50%, you’ll obtain a good quality product, making the most out of the yield.

Once the flowers are completely dry, it is time to start curing them. This process consists of placing the previously trimmed flowers in air tight containers and storing them in a fresh, dark and dry place. Checking humidity levels daily is highly advisable in order to minimize possible problems.

As a general rule, if marijuana is preserved in optimum conditions, it can last for various months without going bad. Although, as it happens with any other plant, as time goes by, it loses some flavor and properties.

Does weed go bad?

The answer depends on its preservation. If not stored properly, it can get overly dry or moldy. However, one of its qualities is that it doesn’t go bad, although it will lose some of its potency, flavor and quality. At least one of the following circumstances will take place without proper preservation methods.

  • Containers exposed to sunlight. Cannabis chemical compounds can change when stored in a place with too much heat and sunlight. THC, its psychoactive component, starts off as THCA, until its carboxylic acid content gets heated. Same thing happens with THC when exposed to ultraviolet lighting, because the chemical reactions won’t stop.

Slowly but surely, THC starts losing its potency and transforming it into CBN or cannabinol, a cannabinoide that relieves pain and insomnia, boosts bone growth and acts as a very strong sedative. When cannabis loses some of its properties, it produces a very strong sedative and relaxing effect.

  • Containers placed in a humid and hot place. In this case it has probably grown mold. This weed is not suitable for human consumption as it would be very harmful due to its microbial spores. Ingesting cannabis with mold can produce serious adverse effects, including a pulmonary infection.

If it grows and cures under proper conditions, it’s unlikely for cannabis to grow mold. Although, if you don’t care for it properly, then such problems are likely to arise.

How long does marijuana last for?

When properly stored, weed can last for months or even years. Normally, if the jars aren’t stored under direct sunlight in a humid place, there shouldn’t be any problems. Oxygen and light are the two main causes of cannabis degradation, therefore, avoid them.

To slow this process, it is best to preserve cannabis in a dry, fresh and dark place, using an adequate recipient, airtight if possible. A glass jar filled to 80% of its capacity is a good way to avoid humidity, as if there is too much air left inside the jar, buds can get too dry.

How to recognize marijuana that has gone bad

You can detect if cannabis is in a good stage by its flavor and aroma. Be especially attentive to the following aspects to make sure it is suitable for consumption.

1. Aroma

Terpenes are the first cannabis compound to be affected by its storage. They are very fragile and start disappearing, which affects aromas. The best way to find out if terpenes are still around is to smell it. Its aroma should be pungent and intense. In certain cases, it can have some earthy touches.

If it’s not the case, there is no need for concern. However, if it smells rancid, similar to used socks (with sour touches), it’s most likely because it has mold. In that case, throw it away.

In both cases, you’ll need to use alternative conservation methods to prevent it from happening again.

2. Looks

If after smelling it, you still have doubts regarding its consumption suitability, take it out and have a close look at it using a magnifying glass. You could be facing two possibilities:

  • The product is yellowish. Old cannabis is brittle and degrades easily. If when you take it out it looks harsh and yellow, leaving behind a great amount of dust, it means its harvest took place a long time ago. It won’t harm you to smoke it, but it will produce a very different effect to what you’d be expecting, making you very sleepy. Flavor wise, it won’t be great either.
  • The product has a white dust. A clear sign of mold is that the buds feature a layer of white powder. If you notice any white or dull stains, it is best to not consume it and throw it away instead, as doing the opposite would pose a huge health risk.


By squeezing the bud you can perceive if it’s fresh or old. A fresh bud is firm and sticky. If on the contrary, it breaks easily, it means that it is too dry and old.

If when pressing it you feel it is soft, humid or wet, open it up and inspect it carefully for any signs of spider webs or yellow/grayish fluff. These types of residues resemble powder sugar and aren’t suitable for consumption.

4. Flavor

Finally, if after smelling it, touching it and observing it, you are still not sure if you can consume it, then flavor will provide the final hint. Take a small sample and try it out. If it tastes badly, similar to old cheese, throw it away immediately.

How to recover weed that has gone bad

Not everything is lost with old cannabis. Some tricks can help restore some properties and improve the flavor and smoke, such as adding an orange peel to the recipient.

There are different ways to rehydrate overly dry buds at home. Some methods include iceberg lettuce, sliced bread or apple. Apples and lettuce are both known for their high water content, therefore, they can be a good solution to rehydrate buds quickly.

On the other hand, there are various products to restore cannabis sponginess, like for example bovedas, which provide the necessary humidity to hydrate the flowers. These products provide a stable and constant humidity to correctly conserve and cure cannabis. Having said all this, even if cannabis doesn’t go bad, it can lose some of its properties. Avoid it with a good preservation system.

29 Seed Saving and Storage Jars and Containers

If you’ve been storing and planting seeds for a garden for a few years, you’ve probably at least once, probably early on, learned the lesson of planting or storing seeds incorrectly. The biggest disappointment about storing or planting seeds improperly is that you don’t find out you’ve done it until they don’t produce.

This can mean not only a delay in getting your garden started but also an unexpected hit to the budget when you have to go and purchase additional seeds to replace the ones which didn’t produce due to your error.

For the most part, any airtight container, made of glass, plastic, or metal can be used to store seeds. Containers for planting seeds are even more diverse.

But while there are many different types of containers that can hold your seeds safely, there are some other factors depending on your goal for the seeds.

Containers That Can Hold Your Seeds for Saving

Any container you intend to use to hold your seeds for saving should be airtight. The container itself can be made from plastic, metal, or glass as long as it is indeed airtight.

To properly save seeds, you also need to keep them in an area that is dark and stays cool without extreme fluctuations in temperature.

It’s also important to make sure seeds are dry before you place them into your storage container and that the area you choose to store them in is dry as well.

Seeds that snap in half when bent are dry enough for storage. Moisture is the primary enemy when storing seeds. Most seeds come in paper envelopes or seed packets.

You can leave them in the packets or take them out as long as your container is airtight. Below are some suggestions for containers that can hold your seeds for saving:

  1. Tupperware containers
  2. Vitamin bottles
  3. Glass jars
  4. Ziplock bags

Storage time is another enemy when storing seeds. Most seeds have a shelf life even when stored in optimal conditions.

  • Short Shelf Life (1 to 2 years) are things such as peppers, parsley, okra, sweet corn, parsnips, and onions
  • Medium Shelf Life (3 to 4 years) are seeds for watermelons, tomatoes, anything in the cabbage family, beans, carrots, beans, celery, pumpkin, squashes, turnips, peas, beets, peas, and spinach
  • Long Shelf Life (5 to 6 years) include radish, cucumber, and lettuce seeds.

Containers That Can Hold Your Seeds for Starting Plants

When it comes to starting your seeds or planting them, there are a wide variety of containers that can be used. The containers you use to hold your seeds for planting really depend on your budget and your imagination.

The only requirements for containers is that they are at least 2” deep and can provide good drainage.

This means that in addition to all kinds of store bought planters and pots, you can reuse just about anything to hold your seeds for planting.

We’ve listed a wide variety of containers to consider below. The containers you choose will depend largely on what you are planting and the types of seeds you are using.

  • 5. Aluminum or foil pans
  • 6. Plastic black flats
  • 7. Landscaping cloth bags
  • 8. Empty Butter Tubs
  • 9. Plastic deli containers
  • 10. Yogurt containers
  • 11. Cell packs
  • 12. Biodegradable Pots
  • 13. Styrofoam or Plastic Drinking Cups
  • 14. Soil blocker cubes
  • 15. Paper egg cartons
  • 15. Reclaimed plastic nursery pots
  • 16. Hydroponic Net Pots
  • 17. Peet Jiffy Mesh Pellets
  • 18. Cone-Tainers (store bought)
  • 19. Root pruning air pot containers
  • 20. Cottage cheese containers

Containers That Can Hold Your Seeds for Planting

Once you have your seeds started, they will be ready for planting. But sometimes planting your seeds directly into the ground just isn’t feasible.

Perhaps you live in an apartment building without much soil or only a rooftop area for planting. Or, maybe you are renting your home and your landlord is hesitant to allow you to till up the ground. In some cases, the soil where you live may be rocky or otherwise difficult to grow plants in directly.

Containers that can hold your seeds for planting are especially great in areas where the ground or topsoil could be contaminated by runoff or other toxins.

Reasons to Use Container Gardening

Container gardening is also really great for anyone who may be in a temporary living arrangement because planting in containers doesn’t disturb soil. It’s great for anyone who has limited ground space because it can be done in very small spaces rather than one large rectangular or square garden bed..

Planting your seeds in containers gives you the ability to make your garden portable or at least semi-portable. This is great for anyone who is hoping or planning to move to a new location but is uncertain of timing.

You can get your garden started in containers and simply move it with you when you relocate. Container gardening is also a great way for preppers to make part of even all of their garden portable in the event of a bug out scenario or SHTF event.

Using containers to hold your seeds for planting is also a great idea for anyone with limited mobility. Using containers nearly eliminates the need for weeding, it allows you to bring your garden to a convenient location near your home, and it elevates the plants off the ground which reduces problems with pests.

  • 21. 5-gallon buckets
  • 22. Laundry Baskets
  • 23. Old Boots or Shoes
  • 24. Clay Pots
  • 25. Terra Cotta Pots
  • 26. Plastic Planter Pots
  • 27. Window Planters
  • 28. Hanging Pots
  • 29. Sub-Irrigated Planters (SIPs)

When choosing the containers to hold your seeds for planting, make sure you consider plant quantity, initial container cost, the size of the plants you want to plant, and whether the container will be reusable or whether you will need to repurchase each year.

As long as you store your seeds properly, you can produce your own food to supplement your food stockpile and help feed your family. Using containers that can hold your seeds doesn’t have to break your budget either.

How To Store Your Marijuana

If your medical marijuana is currently sitting inside of a plastic ziplock bag, this blog post is for you.

We’re going to assume that when you go to the dispensary, you don’t walk up to the budtender and say, “Bring me the most dried-out, flavorless, weakest strain of cannabis that you have. I want the kind of stuff that’s going to make me cough my lungs out once I inhale it.”

No, you would never order something like that. You probably want the best quality of medical marijuana that you can afford.

So here’s the question: if you don’t want the worst quality of medical marijuana, why would you store it in such way that you get the worst quality?

Because when you store high-quality marijuana improperly, you might as just buy the low-grade stuff. That way, you’ll at least save money.

But if you want to preserve your cannabis the right way and keep it fresh for months (or some cases, even years), then it’s time to learn how to store your marijuana properly.

The 3 Enemies Of Fresh Marijuana


The reason: UV light will break down your marijuana’s cannabinoids and terpenes, severely impacting its potency.


The reason: Too much exposure to air will dry your marijuana out. It’ll lose its flavor and burn harshly when you light it. If you normally have trouble holding marijuana smoke in your lungs, dried-out marijuana is even worse.


The reason: Mold spores love environments with high humidity. If your marijuana is kept in a dank, humid environment, don’t be surprised if mold finishes off the rest of your cannabis before you do.

How To Store Your Marijuana The Wrong Way

1. Put it in a plastic bag

Marijuana is medicine; it’s not a sandwich.

Plastic bags are useful when you want to store food temporarily and eat it later in the day.

But they’re a bad choice for marijuana storage because air can move in and out of the bag far too easily.

In fact, if you fill a plastic bag with marijuana and zip it up, you’ll probably still smell the marijuana through the bag.

That means your marijuana’s flavor is literally leaving the bag. You don’t want the flavor to leave; you want it to stay in there so that you can enjoy it yourself.

And if the air inside the bag is getting out, it also means that the air outside the bag is getting in. That’s a recipe for dried-out, nasty-tasting marijuana.

Here’s another issue: household plastic bags can carry a static charge. This charge will pull the trichomes off your bud. Trichomes are responsible for creating marijuana’s cannabinoids and terpenes, so when you remove your cannabis from the bag and lose those trichomes in the process, you’re losing the most potent part of the plant.

2. Store It In a Refrigerator Or Freezer

Putting marijuana in the refrigerator is an all-too-common tactic. Unfortunately, it’s a bad one.

The key to preserving your marijuana is keeping it at a temperature that you can control. The temperature and moisture inside of a fridge are difficult to control, and that means mold might an opportunity to grown on your medicine.

Freezers aren’t much better. When marijuana freezes, its trichomes (those cannabinoid/terpene factories we were talking about earlier) become brittle and can easily break off and be lost.

3. Keep It Near Electronic Devices

Electronics are constantly emitting heat. If your marijuana is resting on top of your refrigerator, television or computer, it’ll absorb that heat and dry out more quickly as a result.

How To Store Your Marijuana The Right Way

1. Use a Sealable Glass Container

You really can’t go wrong with glass. Why? Because glass containers are impermeable, which means it’s extremely difficult for air to get in or out.

Of course, you’ll need a glass jar with an airtight lid. Mason jars are a great option, and you can easily get one from your local home supply store. Just be sure to get a jar that’s appropriate for the amount of marijuana you’ll be storing. You don’t want to store 1/8 of an ounce in a huge jar. That will leave more air inside the jar, and your marijuana will dry out more quickly.

2. Keep It Out Of Sunlight

Keep your medicine in a drawer, closet, cupboard, time capsule – whatever. Just as long as it’s something that will shield your medicine from those cannabinoid-destroying UV rays. For an added layer of protection, keep your medicine inside of an opaque or dark-colored glass jar.

And be sure to put your weed away after you’re done using it. It can be tempting to leave out your bud after you’ve smoked a bit. After all, you probably want to relax and enjoy some pain relief, not worry about keeping the place tidy. But it only takes a few seconds to put your cannabis away where it belongs; that’s a small price to pay for fresh marijuana.

3. Keep It In A Cool Dry Place

We said earlier that too much heat can dry your marijuana out. Once you add moisture to the mix, now you’re dealing with an even bigger problem: mold.

But you also don’t want the environment to be too dry; otherwise, you run the risk of your marijuana drying out.

You want the relative humidity level of your storage environment to be somewhere between 55 and 62 percent. It may be difficult for you to maintain that percentage range, especially if you live in a humid city or town. If that’s the case, consider investing in a cannabis humidor. These devices allow you to store your marijuana in a humidity-controlled environment that’s also protected from sunlight.
