So, you’ve inoculated your grain bag, and you realize you’ve got a lot more mushroom spores leftover than you thought.

Many first-time cultivators find themselves in this position and at a loss of what to do with the excess.

Do you throw your syringe away? 

Definitely not!

Instead, you can store your mushroom spores and use them again in the future. Not only will you save loads of money, but you can also start putting together your own strain library.

While this process may sound appealing, you can’t just toss a syringe into your cupboard and leave it there. 

You’ve got to preserve the mushroom spores correctly if you want to guarantee successful harvests in the months to follow.

Join us as we investigate how to store psilocybin spores effectively and how long you can expect them to last.

We’ll also take a look at how they germinate and common practices you should avoid, ensuring premium quality shrooms every time.

Without further ado, let’s venture down this rabbit hole.

 

Store Your Mushroom Spore Syringe

 

How Long Do Spore Syringes Last?

The first thing you’re probably wondering is how long mushroom spores in a syringe will last?

There are a few factors that determine the expiration date, such as the temperature and quality of the container.

For the most part, spores in a laboratory-grade syringe left out at room temperature will last up to 30 days.

Trying to inject the liquid solution into a grain bag after this period will produce incredibly low yields if any.

The above time frame is more of a recommendation to ensure customers get the most out of their chosen strain.

A recent discovery shows a single mycelium spore staying dormant for over 250 years, so anything is possible. 

You can significantly extend the shelf life of your unused spores by storing them in a cold, dark place.

When preserved in a fridge, syringes filled with mushroom spores can last between four and twelve months. This technique ensures successful germination and generous yields.

Extend this time by preventing light from reaching the plastic syringes and maintaining a constant temperature around them.

How to Store Mushroom Spores

While everyone puts their own unique spin on storing a mushroom spore syringe, the process remains relatively straightforward.

To ensure you have the best chances of preserving for favorite psilocybin strain, follow these simple steps:

  1. After inoculating your grain bag, use an alcohol wipe to sterilize the entire syringe.
  2. Put on the protective cap to ensure no solution drips out.
  3. Get one unused sealable plastic bag and sterilize it with more alcohol wipes.
  4. Place your mushroom spore syringe inside the bag.
  5. Try to remove as much air from the bag as possible before sealing it.
  6. Leave the syringe in an area of your fridge where it won’t be disturbed.

When you decide to inoculate another bag, remove the mushroom spore syringe and inject it as normal.

Another handy tip is to label your syringes and sealable bags to avoid mixing up strains. This method also makes it easy to start putting together a magic mushroom spore library.

 

Why You Probably Won’t Want to Freeze Your Spores

There’s a common misconception in amateur mycology, suggesting that storing a spore syringe in a freezer is ok.

Mycelium seeds don’t die when exposed to extreme temperatures. Instead, they go into a dormant phase.

With that being said, leaving your spores in a freezer is generally considered a bad idea.

As the liquid solution expands and freezes, ice crystals can rupture the structure of the mushroom spores.

Although a few strains of fungi can survive this method, it’s best to avoid it entirely.

If you insist on freezing your spore syringe using this technique, it’s recommended to use a chest freezer rather than a household unit.

 

When Do Spores Germinate?

Mycelium spores begin germinating when they’re exposed to water and oxygen, much like a plant seed.

It begins with a single mushroom releasing over a billion spores from its gills. These seeds then travel, usually via wind, until they land in a moist area.

Temperature plays a vital part in the germination of spores. Anything too hot or too cold will prevent this growing process from triggering.

Once the spore senses that the conditions and moisture levels are favorable, a network of individual threads, known as hyphae, spreads out.

As a collective, these growing tentacles are known as a gametophyte. It’s during this stage that the mycelium begins producing its reproductive cells and spreads.

The time it takes spores to germinate depends on the strain and can range anything from 5 minutes to 19 days.

This initial growing process occurs without the need for any external equipment. Everything the spores need to survive and germinate is located within them.
