How to Store Mushroom Spore Syringes & Spore Prints

At PNW Spore, Co., we take great care inspecting and packaging each individual P. Cubensis multi-spore syringe, spore print, and gourmet/medicinal liquid culture syringe before shipment. Here are some Spore Storage Tips for your new syringes!

What is the best way to store mushroom spores?

Spore syringes can be stored at room temperature, out of direct sunlight, but they last significantly longer when placed in the refrigerator. Ideally, you would keep your syringe(s) in the original packaging and place in the refrigerator until you begin your research.

It is important to store your mushroom spore prints in a sealed container and in a dry, cool location that is out of direct sunlight. The spores that make up the print can be exposed to contamination and activation if exposed to air exchange and humidity. If you live in a high humidity environment, prints can be stored in an airtight plastic pouch and in the refrigerator. Do not freeze your prints as this could damage the spores. Spore prints can remain viable for years is properly stored.

If you are beginning your research right away (within a week or two), room temperature, out of direct sunlight, is just fine.

Can spore syringes be frozen?

Spore syringes should NOT be stored in the freezer as this will damage the syringe, making microscopy research difficult.

How long do mushroom spore syringes last?

High quality spore syringes from a reputable company can be kept in the fridge for 18-24 months. However, some researchers have stated that they have stored spore syringes for multiple years and have found them to be viable for microscopic research.

How long do liquid culture syringes last?

Our gourmet & medicinal liquid culture syringes should be kept in the refrigerator in the same manner as our Psilocybe Cubensis spore syringes, and should be used within approximately two to three months. The variables for longevity of a liquid culture syringe are highly dependent upon nutrients present in the solution. 

We produce our liquid culture syringes in small batches at great frequency to ensure a nutrient-rich solution. See more customer FAQs here about Pacific Northwest Spore, Co. spore syringes, including shipping & more.
