We at the Fungi Academy believe in the potential of mushroom liquid cultures when it comes to home scale mushroom growth!
They are simple and inexpensive to construct, incredibly scalable, colonize grains far faster than agar cultures, and may be used to create an infinite number of liquid cultures or to inoculate grains in non-sterile conditions. That is unparalleled for small-scale producers when compared to other growth strategies.
In that spirit, we thought we’d give you a crash course in mushroom liquid culture.
What exactly is mushroom liquid culture?
A mushroom liquid culture is just live mycelium suspended in mildly nourishing water. 500 millimeters of filtered, non-chlorinated water coupled with 10 grams of honey, light malt extract, or any simple, readily fermentable sugar is a basic, standard recipe for this healthful water combo.
What is the difference between a liquid mushroom culture and a spore syringe?
As previously stated, a mushroom liquid culture is just mycelium growing in liquid.
Spores and spore syringes, however, are not mycelium. Before spores to produce mycelium, they must first germinate. When you inoculate a substrate with spores/spore syringe, it must germinate before it can start growing mycelium. When a substrate is inoculated with a mushroom liquid culture, it instantly begins to develop (additional) mycelium. Check f+ spore syringe for sale here.
What are the advantages of mushroom liquid cultures?
The most significant advantage of mushroom liquid cultures, in our opinion, is that once you have a clean mushroom liquid culture to work with, you may inoculate grains in a non-sterile setting such as your kitchen counter.
This eliminates the need for a Still Air Box or a flow hood, decreasing the barrier to entry into small-scale home mushroom farming significantly. Because the chance of contamination is minimal, there is less failure, which sometimes discourages novices from continuing on their mushroom gardening path.
Other advantages of mushroom liquid cultures are their rapid colonization rates (the more liquid culture you use, the quicker the colonization), simplicity of manufacturing and extending mushroom liquid cultures, and low cost of production. Even in today’s bizarre world, water and honey are rather inexpensive.
What are some of the difficulties associated with dealing with mushroom liquid cultures?
We’d be remiss if we didn’t point out a few disadvantages of mushroom liquid cultures. For one thing, when you initially create a liquid culture, it is vulnerable to contamination.
Then there’s the problem that contamination in mushroom liquid cultures might be difficult to detect. That’s why trustworthy sellers put their cultures through rigorous testing before selling them. However, for the novice, a sterile environment and some basic lab equipment and abilities are required. Purchasing a tiny syringe of liquid culture from a specialist and then expanding it yourself avoids this problem.
Another problem is that in order to maintain your liquid culture vibrant and healthy, you must agitate and oxygenate it, which necessitates the use of a stir plate. You could twist your culture by hand every day, but it’s not ideal.
