Even though spore syringes and liquid cultures equally give indicates to inoculate substrates, you will find crucial differences:
one) Only Lower a little piece(s) of mycelium on agar employing a scalpel. Open up the jar with sterile liquid media and set the agar into it for more expansion. That is it!
After sterilization, transform off the warmth and allow the force cooker to cool down By natural means. Avoid attempting to quicken this method by opening the force valve or eliminating the lid, as sudden temperature or pressure changes could potentially cause the jars to interrupt.

At that stage you can possibly take a slice of your healthful mycelium and insert it directly to your spawn materials, or add it to liquid culture so as to continue increasing extra.
Now, inject the mycelium suspension into your substrate containers more info via their injection ports. A standard rule is to employ about 1-2 milliliters of liquid culture for every pound of substrate.
Then there’s The truth that it can be challenging to determine contamination in mushroom liquid cultures. That’s why reputable vendors check their cultures before sale.
Usually, a bit of the mushroom is chopped up within a blender and after that included for the liquid media. This system is particularly favored by farmers cultivating edible mushrooms.
