Why Use Liquid Cultures

Traditional cultivation methods can be tricky. Liquid cultures come delivered ready to use, saving you many of the time-consuming or difficult steps. Some of the advantages over traditional cultivation include:

 

  • Accelerated Growth: Substrates colonize up to 3x faster with liquid than with spores, bringing you results faster.
  • Higher Success Rates: Because the mycelium is pre-germinated, you get consistent results with significantly fewer failed batches
  • Multiple Harvests: Create dozens of projects from a single syringe through expansion to grain or liquid media
  • Cost-Effective: Since one culture can be expanded into multiple projects, your cost per harvest is lower. 
  • Cleaner Results: The established, vigorous mycelium reduces the chance of contamination compared to spore methods. 

Step-By-Step: Growing Mushrooms with Liquid Cultures

Getting started with our liquid cultures is an easy, five-phase process:

Prepare Your Workspace

  • Clean your work surfaces with 70% isopropyl alcohol
  • Get sterile gloves, a face mask, and a flame source (alcohol lamp or butane torch preferred) 
  • Turn off any fans or air conditioning to minimize contaminants from airflow
  • Consider using a still air box or flow hood for increased contaminant protection

Prepare Your Substrate

  • Choose a substrate – Grain (rye, wheat, millet), sawdust, or hardwood are common choices
  • Sterilize your substrate using pressure cooking methods (15 PSI for 90-120 minutes) 
  • Allow substrate to cool overnight before inoculation
  • Check cooled containers for signs of contamination before proceeding

Inoculate Your Substrate

  • Gently shake the liquid culture syringe so mycelium is evenly throughout the solution 
  • Sterilize the needle under a flame until red hot, then cool for 5-10 seconds 
  • Inject 2-4cc of culture per quart/liter of substrate, using multiple injection points 
  • Seal injection holes with micropore tape, to allow gas exchange while blocking contaminants 
  • Label the culture type and inoculation date on containers for easy tracking

Incubation Period

  • Store in a dark location with warm (70-75°F/21-24°C) stable temperature 
  • Look for white, rhizomorphic mycelial growth spreading from injection points 
  • Depending on species and conditions, full colonization typically occurs within 10-14 days
  • Shake grain spawn at 30% colonization to spread out mycelium and speed up colonization

Fruiting Conditions

  • Introduce fresh air and indirect light when fully colonized 
  • Keep humidity levels between 85-95% using a humidity tent or other system 
  • Harvest mushrooms when caps are fully expanded but before spore release 
  • Enable multiple flushes by maintaining proper humidity and moisture levels
