Growing Guide
Hi and Welcome. Ever wondered: “How to grow mushrooms”? After completing, you can grow most decomposting mushrooms such as Pleurotus, Hericium and Psylocybe species. Start by setting up your work environment cheap, go to the phases of cultivating step-by-step and find all the necessary materials in a shopping list. This is my Hometek.

The SAB (Still Air Box)A SAB is just a clear box with 2 holes for your hands in it. You wipe everything down and put it inside the box. Then you spray it out with soap water, so the box and the air inside are free from contamination. Work slow inside and never hold your hand above anything, you and your skin are bacterial breeding grounds. Experienced cultivators who use hepa filters also are in need to have a SAB nearby. Laminar flow hoods would spread contaminations through the air, so only useable on clean cultures. SAB is best.

Step 1: Agar
Normally you receive a culture on agar, as spores or as liquid culture. Back them up on agar or clean them out. LMEA (light malt extract agar) can be use for a huge variety of species and it is available nearly anywhere.
Recipe:
-500mL cold water
-10g agar-agar powder
-10g light malt extract powder
Mix together and pour into a container. Liquid needs less time in the pressure cooker, because the water acts at itself as sterilizer:
-with a 15 psi model, which are typical in the US 30-60 min
-EU pressure cookers are working standard 0,8 bar (11,6 psi), i sterilize arround 90 min

Step 2: Breed
You could just pasteurize the substrate and create clean grain spawn. You could also use your waste to grow them on. They are decomposers, but we wanna have the lowest effort. So let’s use proven substrates and throw everything together in grow bags.
Different species, favor different substrates. But most of them like rye berries. Use any grain to breed your fungi.
Setup before makeing fruiting blocks
Pressure cooking times:
-in the US for 90-120 min @ 15 psi
-EU pressure cookers are working standard 0,8 bar (11,6 psi) that means 200-240 min

Step 3: Fruit
If you followed my guide, you successfully made a sterile fruitingblock, with only the mushroom culture inside of it.
Let it bee some time and do not mix the top layer of the grain untill its fully colonized.
In the meantime we can do the fruiting chamber.
In an unmodded tub you can grow the most dungloving species, also reishi, shiitake & others. Take a look at the CO2 level in the fruiting phase, it must be higher. Besides that i spray the walls of my tubs when they are dry, nothing more.
Some species like more oxygen, mostly woodlovers, then you need to add FAE & humidity

On the World
The world’s an inn; and I her guest.
I eat; I drink; I take my rest.
My hostess, nature, does deny me
Nothing, wherewith she can supply me;
Where, having stayed a while, I pay
Her lavish bills, and go my way.
-Francis Quarles (1592–1644)
