Turn one spore or culture syringe into 30 syringes!

Our liquid culture expander kit saves you time and money by allowing you to easily turn a single 10ml culture or spore syringe into 300ml of liquid culture without the use of expensive equipment. Formulated for swift spore germination and rapid mycelial growth, our sterile, nutrient-rich “expander broth” was formulated by mycologists and is the ideal environment for growing mycelium.

Rapid spore germination and mycelium cloning

In just 7-14 days, your “expander broth” will contain vibrant liquid culture which can be refrigerated for up to 4 months. Use liquid culture to inoculate a variety of sterile substrates (including sterile grain bags, grain jars, and all-in-one grow bags). A simple, cost-effective solution for both large and small inoculation projects!

Note: A culture or spore syringe is required to use this kit.

Kit includes:

  • (1) Jar with 300ml sterilized media
  • (1) Lid with self-healing injection port and 0.22 micron filter
  • (1) Reusable silicone jar lid cover
  • (1) Sterile 60cc syringe
  • (1) Sterile 14 gauge needle
  • (2) Alcohol wipes
  • (1) Instruction manual

Recommended add-ons:

Upon arrival:

Liquid Culture Kit is best used within one month of receipt. We recommend waiting at least one week after arrival before injecting your Liquid Culture Kit to ensure it wasn’t compromised in transit. If the liquid appears cloudy, it is compromised and should be replaced. (We guarantee replacements – just reach out!)

Storage:

Store in a dry place at approximately 50-70°F until use. Once fully colonized, the liquid culture can be stored in the refrigerator for up to four months!

Note: Do not refrigerate pink oyster or almond agaricus.

Works Great!

I’ve bought a few of these and only once have had an issue with contamination. That’s why the recommended letting it sit. Luckily I let it sit out before I used it and dint waste my spores. Northspore customer service was top notch and sent out a replacement right away. Remember to keep the jar, it’s reusable. Reason for the 4 and not a 5 star review is honestly these should come with a magnetic sir bar.

Very simple and easy but effective

Instructions were easy to follow for someone who has never used before. Took but a minute to read and understand. Another minute to perform the task. Already seeing results!
