Product brand: North Spore
The details
Multiply any spore or culture syringe into 30 syringes!
Our liquid culture expander kit / spore booster 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 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
For best results:
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:
Our Liquid Culture Kit is best used within one month of receipt. 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.)
