 ==== '''Day 1 Prepare agar medium flat jars''' ====
+Objective: Prepare a versatile nutritional medium for mushroom cultivation.
+Materials: Flat jar, wadding, agar-agar, malt extract powder, marker, distilled water, pressure cooker, precision scale (0,1 g), aluminum foil.

+<u>Part 2: Weigh Ingredients And Mix Into Flask</u>
+* Use a scale to measure the required ingredients accurately.
+* Construct a container using clean aluminum foil or paper.
+* Combine the ingredients in a flask or jar, ensuring thorough mixing.
+* Create a hole in the lid and insert cotton wadding to enable pressure cooking and facilitate air exchange for the mushrooms.
+* Pour enough of the mixture into each container to cover the bottom adequately. (A thicker agar layer consumes more materials but prevents drying during long-term fridge storage.)
+* Seal the jars and cover the lids with aluminum foil to prevent microbes from reaching the air filter later on.
+<u>Part 3: Sterilize In Pressure Cooker</u>
+* Add a few centimeters of water into the pressure cooker, ensuring the vessels are submerged but not floating. Close the cooker and reach the designated temperature and pressure point (121°C, 15 PSI). (Avoid using airtight containers in the pressure cooker to prevent bursting; always refer to the pressure cooker manual for proper usage.)
+* Reduce the heat to maintain a gentle boil and keep it at the minimum temperature to ensure the water continues to boil.
+* Wait for 40 minutes from the point when pressure and heat are reached.
+* Turn off the heating source and allow the cooker to cool down naturally. HINT: Avoid releasing pressure suddenly as it may cause the medium to overboil.
+* Once the cooker is slightly warm, release the remaining pressure (there should be none), open the lid, and carefully remove the medium.
+* Let the jars cool down naturally before storing them in the fridge.
+<u>Part 4: Add  Mycelium</u>

 ==== '''Day 3 Preparation of a Small Bag with Substrate''' ====
+Objective: Prepare a sterile small bag to expand mycelium for fructification, fabrication, or as an inoculant for larger vessels.
+Materials for 1 bag: See below, bucket that can hold 5 L (for mixing), jar with clean grain spawn, substrate, '''alcohol(?)''', autoclavable plastic bags, gloves, distilled water (approx. 2,5x the dry weight of the substrate).
