In this article, we will answer the question, “What is the shelf life of mushroom spores?” and discuss the best method for storing mushroom spores.

What is the shelf life of mushroom spores?

Mushroom spores can live for up to two years, depending on the type and variety of mushroom.

If you bring them out to germinate after a few years and they don’t respond, rehydrate them and then germinate.

Months-old spores should always be rehydrated before germination.

Mushrooms should only be stored in syringes for one month. After one month, there is a greater chance of bacteria growth in the water. Refrigeration is the best option for extending the shelf life of a syringe.

Unless they will be used quickly, liquid culture syringes should always be kept in the refrigerator. They should be stored at room temperature, with the exception of the Pink Oyster cultures.

On liquid culture syringes, we provide a 45-day viable guarantee. On spore prints and spore syringes, we offer a 60-day viable guarantee.

Most vendors in this industry offer 30 days or no guarantee at all on spores, so we believe 60 days is ample time to determine whether or not there are any issues.

Can mushroom spores spoil?

The term “viable” refers to mushroom spores that have gone bad. It means that the spores are in a similar state to when they were discovered in nature.

However, it is estimated that mushroom spores can last for many years if properly preserved and not contaminated.

Many factors influence the storage and preservation of mushroom spores, including:

Are the spores in print or in a syringe?

The temperatures at which the spores are stored, the type of mushroom from which the spores are collected, and the strain’s unique characteristics
If we make a comparison between the print and the spores from a syringe. Print spores typically have a longer shelf life.

It has been discovered that print spores have a very long shelf life, lasting up to a few years. With some anecdotal evidence, you can extend it to a total of ten years.

What is the best way to keep a spore print?

The best way to store it is in an airtight bag and then in the fridge until needed.

Because the spores die at 122 degrees Fahrenheit or 50 degrees Celsius, it is best to keep it at low temperatures to avoid spoilage or before it becomes viable.

Spore prints Spore prints are primarily used to preserve spores.

Another use for spore prints is mushroom cultivation, identification of the mushroom class or strain, and preservation.

How long can spore syringes be used?

Because the culture may also grow other bacteria, spore syringes should be stored in a cool, dark, and shady location.

If you intend to study them for research purposes, keep them for no more than 30 days.

This is a broad and speculative hypothesis; according to some studies, these spores can be stored in the refrigerator for many years.

Spore syringes are widely used because they are simple to use and store. Despite their shorter shelf life, amateur microbiologists used them for this reason.

Is it possible to freeze spore mushrooms?

It all depends on the type of mushroom you’re preserving. If they contain psilocybin, freezing or refrigerating them is not a good idea.

There is a chance that the spore will survive at this temperature, but there is also a chance that it will not, so do not freeze them to save money.

Other mushroom spores can easily withstand this temperature because they are not affected by freezing. They simply gain viability.

The type of freezer you use is the second most important factor in freezing. The temperature in a typical household freezer is higher than in a deep freezer.

The freezer at home can cause cracking and damage to the aqueous solution. While the other keeps the temperature constant throughout.

To summarize, do not freeze mushroom spores.

The best way to keep mushroom spores

The best method is to keep them in the syringe in a cool, dark place, such as a refrigerator, and to study them as soon as possible. Otherwise, you’ll only have about 30 days before they spoil.
