How to Store Shrooms

March 26, 2020

You’ve gone through all the trouble of making your own substrates, cultivating your fungi in mushroom casings, and now your bountiful harvest of fresh psilocybin mushrooms are ready to be dried and stored.  What’s next? Drying and storing your homegrown magic mushrooms can seem like an annoying chore, but these are crucial final steps that if overlooked can lead to disaster.  Mold, rot, harmful bacteria and a slew of other problems can crop up if you don’t spend the time & effort on drying and storing your mushrooms properly.

There are many ways to store your mushrooms, but the setup you choose will likely depend on your financial or spatial resources, and whether you’re storing fresh or dried mushrooms.  If you don’t devote enough time to storing magic mushrooms you might risk diminishing their potency, quality, flavors or even speed up the rate at which they decompose.  Ask any stoner or shroomer and they’ll tell you: just like storing & curing cannabis is an absolutely essential step to achieving the highest quality product possible, storing psychedelic mushrooms effectively can ultimately decide their potency and quality.  Think of storing mushrooms as sealing or locking in the active compounds, flavors, textures and aromas of your mushrooms.  If you don’t control the environment within your storage containers and maintain ideal conditions for preserving potency, all that work of making substrates and growing your mushrooms from spores to bloom could be for nothing.

When you’re learning how to store psychedelic mushrooms it might seem like the best ways to store shrooms are obvious or straightforward – using air-tight containers, keeping them out of direct sunlight and maintaining favorable conditions.  This is true for most experienced mushroom growers, but when you’re starting out you need to take the time and extra effort to ensure you’ve rigged up stable conditions, securely sealed containers and controllable storage rooms.

It’s time to learn the best way to store shrooms so that your psychedelic journey isn’t thwarted before you even have a chance to get started.  Let’s pry open the lids of some of the best storage containers and methods for storing mushrooms.



There are basically three different schools of thought on storing mushrooms: storing fresh mushrooms, dried shrooms and frozen psilocybin.  Some people have very strong opinions about which way to store shrooms is best, but ultimately it is up to you.  When you’re considering what kind of mushroom storage to invest in, you should first consider a few factors:

  • What kind of space do you have available? An entire fridge/freezer? A dark, cool room? Room in the garage for a container?
  • How many mushrooms are you growing? One crop or several at a time?
  • Will you be consuming your mushrooms fresh? Or drying them to have over time?
  • Are you microdosing psilocybin? Or seeking psychoactive effects?
  • Do you have a medical need for magic mushrooms? Or do you consume them recreationally?

Answering these questions first will help you to determine which way of storing mushrooms will suit your needs.  Do you grow your own psychedelic mushrooms for an important, medical reason? Are you an experienced enough cultivator that you can handle multiple mushroom blooms at one time? How much psilocybin will you be consuming, and how often?

Your available space, equipment, know-how and ability to DIY vs purchasing necessary items will also go a long way in determining what kind of mushroom storage you use.  Fresh mushrooms will require a lot more temperature & moisture controls in addition to container space than dried or freezer stored shrooms.  On the contrary, not everyone has a large deep-freeze in their garage, or rooms where they can easily dry and store shrooms.  You don’t have to spend a lot of money to properly store your mushrooms, it simply depends on what kinds of setup & materials you have available in your home.

Without further ado, let’s look at the different techniques on how to store magic mushrooms.


Storing Fresh Mushrooms

To begin with, many people who are proponents of magic truffles and prefer the tastes & textures or fresh mushrooms will store them right after harvesting.  Storing fresh mushrooms can be simple and easy, but you still need to make sure you’re monitoring them often and continuously maintaining the right conditions.  Because fresh mushrooms have not been dried, they can be more susceptible to mold, bacteria and other issues of decomposition.  That being said, if you’re storing fresh shrooms then you’re probably planning on consuming them fairly quickly (as they don’t keep more than a month or so).

Fresh mushrooms need to be stored in the fridge, but if you have no fridge space available the important thing is to maintain a temperature range below 5℃.  Typically, 3℃ is a good middle point, but you need to constantly observe your mushrooms when they’re being stored fresh – any sign of too much moisture, or not enough, can lead to various problems.  If your mushrooms are stored with too much moisture, they might develop mold or harmful bacteria which in turn break the fungi down and reduce their potency.  Conversely, if there is not enough moisture present, your truffles or fresh shrooms might dry out and lose some of the flavors.  Magic mushrooms that dry out too quickly might also lose some potency, so if you’re worried that they are not moist enough simply spray a bit of water vapor on them with a spray bottle (but be careful not to overdo it, remember that it’s a balancing act with moisture).

Fridges are ideal for fresh mushrooms storage because they are inherently moisture controlled environments.  As is common with many of our food storage appliances, moisture build-up can occur over time.  To prevent these happenstances from affecting your shrooms, including some paper towel beneath them will help to soak up any excess moisture.  For instance, many experienced shroom growers will store their magic mushrooms in a container inside the fridge, adding another barrier to excess moisture.  First, put a layer of paper towel in a tupperware container, then place your mushrooms/truffles on top, covered by another thin layer over top of the shrooms.


In order to extend the shelf-life of your shrooms, you can use a vacuum sealer/packer.  These helpful contraptions suck out all the air and moisture, and seal your mushrooms in a completely controlled state for many weeks.  When you use a vacuum sealer, you can stretch your mushrooms’ freshness, potency and consumability by months (typically, vacuum sealed food items can last 2-3 months before diminishing in quality).  You need to dry your mushrooms out, even just a bit, before vacuum sealing them, however, because any resident moisture can lead to bacterial growth even in this air-sealed environment.

Whether you’re making magic mushroom edibles, you’re a savvy cosmonaut who prefers the freshest and best tasting psilocybin, or you’re planning on making your own magic mushroom products at a later date, fresh mushrooms might be the way to go – just make sure you keep a close eye on your precious shrooms during storage.

Storing Dried Mushrooms

If you’re cultivating numerous crops of psychedelic mushrooms, or you’re not planning on consuming them for long periods of time, you’ll need to extend the viable shelf life of your shrooms by drying/curing them before storage.  Dried mushrooms and truffles can be stored and still be potent for a few years (24 – 36 months is a general range for how long properly dried/cured shrooms can last).  The great thing about dried mushrooms is you don’t have to worry as much about moisture, and these kinds of psychedelic mushrooms are typically devoid of bacteria after the drying process.

Drying and curing psilocybin shrooms is a very thorough process, and it can require a lot of practice before you get it just right.  We won’t dive into this complicated procedure in this article but look out for guides on how to dry & cure shrooms in the near future.  In the meantime, the basics for drying & curing magic mushrooms involves removing moisture without using heat.  Why is heat bad for mushroom drying? When you introduce heat into the equation you might dry your mushrooms out too quickly, which can affect the active compounds (psilocybin, psilocin) in your shrooms.  Heat – and light – can alter the chemical composition of almost anything they come into contact with, especially organic materials like mushrooms.  How can you dry your mushrooms without using heat? Keeping them in cool, dry and dark places and using moisture-controllers like desiccants or humidity regulator packs will maintain consistency.  Time if also an uncontrollable element in the drying process, but one that is the most effectual – the more time you can devote to properly drying your shrooms, the better chances of success you’ll have.

When dried, mushrooms are not as susceptible to mold or bacteria growth because their moisture has been removed, and they don’t decompose any further.  Instead, you need to keep them in cool, dark and dry conditions in order to avoid unwanted chemical reactions (light or heat can initiate further decomposition and alter your shrooms’ psilocybin potency).  In order to store shrooms that have been dried, your main focus will be limiting heat or light exposure, whereas with fresh mushrooms you are chiefly concerned with moisture.  Too much direct light exposure, or introducing heat at any point of the drying or storing processes might reduce their potency.  As long as you’re storing them in a dark room/opaque container with a temperature gauge and moisture control pack, you can keep your mushrooms safe and potent for many years.

Storing Mushrooms in the Freezer

If you’ve got lots of room in your freezer or deep-freeze, and you want to go the extra mile when storing your shrooms, storing them in very cold temperatures can potentially extend the long-term viability of your psilocybin.  Freezers essentially suck out all of the moisture from the air, creating a very dry and cold environment where bacteria and mold can’t break down materials or speed up decomposition.

 We talked about heat and how it can diminish potency or affect the membranes of the mushrooms, well you don’t have to worry about any introduction of heat when you store it in the freezer! However, sub-freezing temperatures can also cause damage to the tissues of the mushrooms if they’re not properly dried first.  Never freeze-dry or store fresh mushrooms in the freezer, as the moisture content within the shrooms will be impacted by the sudden drop in temperature/humidity and can cause reduced potency over time.

Once you’ve gone through the drying process and you’re ready to store shrooms in the freezer, place your dried psilocybin in a ziplock bag or sealable container. This will prevent other particles or moisture from getting into your shrooms in case the freezer breaks down or is left open too long.  Make sure that you’re not putting anything on top of your shrooms in the freezer, as any heavy food items or ice-blocks can damage the mushroom tissues and cause the cells to break down.  Try not to check on your mushrooms too often and never remove them from the freezer en masse – when it’s time to trip or microdose, take out the individual pieces that you’re going to consume and don’t take the entire harvest from one environment to another.  The less you change their environmental conditions, the more likely your mushrooms will last as long and stay as potent as possible.

No matter which way you decide how to store psychedelic mushrooms, just make sure you’re paying close attention to the conditions and the potential risks, and you’ll be that much more likely to reap the rewards.


How do you keep mushrooms fresh for longer?

The best way to ensure that your mushrooms last the longest is to dry them first before storing them long-term.  Drying magic mushrooms can be a long, drawn-out process but when you properly dry or cure your shrooms you can extend their shelf-life from 2-3 months to 2-3 years!

Should mushrooms be kept in the fridge?

Fresh mushrooms that have not been dried can be stored in the fridge, but it is not typically recommended that you store dried mushrooms in this way.  Dried mushrooms are more susceptible to light exposure, whereas fresh mushrooms need to be kept in a moisture-free environment in order to avoid mold or bacteria issues.

How do you store mushrooms after washing them?

How to store magic mushrooms will depend on how long you want them to last.  Fresh mushrooms can last up to a month in regular conditions, or 2-3 months if they’re vacuum sealed.  Dried mushrooms can last 12 months or more, but need to be kept in a dark, cool and dry environment.  You can also freeze your dried mushrooms to increase their viability to 2-3 years, but they must be dried properly and left alone as long as possible.

How many days can mushrooms be stored for?

The best way to store shrooms and extend their shelf life will depend on how you consume them and how long you need them to last.  For instance, microdosing psilocybin involves very small amounts of shrooms, therefore you should dry them and store your mushrooms for long-term use (1-3 years).  On the flip side, if you want to experience psychedelic trips you might want to store your mushrooms fresh in the fridge for up to a month of use.
