One of the prerequisites is therefore to have a syringe of liquid culture of the mushroom variety of your choice. It is possible to provide it on the link [https://breizh-bell.bzh/produit/syringue/ following].

| − | '''Introduction to the mushroom cycle'''
| |
| − | | |
| − | What is commonly called "mushroom" is in fact only the temporary and visible "fruiting body": the [https://fr.wikipedia.org/wiki/Sporophore sporophore] (formerly called "carpophore").
| |
| − | | |
| − | It is the result of an organism with a more durable and more discreet character, formed of filaments generally invisible to the naked eye when they are isolated: the [https://fr.wikipedia.org/wiki/Myc%C3% A9lium mycelium.]
| |
| − | | |
| − | The sporophore is often in the form of a [https://fr.wikipedia.org/wiki/Stipe_(mushroom) foot] wearing a [https://fr.wikipedia.org/wiki/Hat_(mushroom) hat] .
| |
| − | | |
| − | | |
| − | To cultivate a mushroom, we try to reproduce the natural external conditions. Mushroom cultivation is divided into three main stages.
| |
| − | | |
| − | #Inoculation: addition of mycelium (in the form of spores or in liquid or agar culture) in the substrate
| |
| − | #Incubation: the mycelium propagates in the substrate
| |
| − | #Fructification: the mycelium wants to reproduce by forming a sporophore
| |
| − | | |
| − | | |
| − | '''Liquid inoculation?'''
| |
| − | | |
| − | In myciculture, inoculation by liquid culture consists of injecting mycelium contained in sterilized sugar water onto a substrate.
| |
| − | | |
| − | | |
| − | '''Why is it awesome?'''
| |
| − | | |
| − | There are several ways to start a mushroom crop. Liquid inoculation is one of the easiest because you just need to spray a substrate with a liquid culture. In addition, the risk of contamination is less than with other methods.
| |
| − | | |
| − | | |
| − | | |
| − | '''Receiving the liquid inoculation syringe'''
| |
| − | | |
| − | Upon receipt of the syringe containing the mycelium, place it immediately in the refrigerator, it must be used within two weeks!
| |
| − | | |
| − | You have two choices :
| |
| − | | |
| − | #Liquid culture copy: The goal is to copy the liquid culture to achieve even more culture! The liquid culture copy is <u>optional</u>!
| |
| − | #Grain inoculation: This consists of depositing a liquid culture on a substrate. Seed inoculation can be done in a jar or in a bag
| |
| − | | |
| − | {{Info|When copying liquid culture, you can only make this copy once. The mycelium weakens with the copies and your crops will not produce correctly.}}

| − | Mycelium: filamentous body of the fungus

| |
| − | |Step_Content=It is very important to have the most sterile conditions possible, throughout the manipulations. Indeed, there is a biological struggle between living species. If the environment is contaminated, the fungus will find itself in competition with other organisms, so it will be too fragile and will lose. We will seek to create ideal growing conditions to promote the fungus.
