Easy Mushroom Growing: How to Make Grain Spawn Using Liquid Culture

In this video, I make grain spawn jars! My favourite way to cultivate a lot of mycelium reasonably quickly!
Materials: Grain Jar
A Big Jar
Silicon Injection Ports
Micro Pore Tape (.22 micron)
Aluminium
Glue
Punch/Drill/Screw Driver
Whole Grain Rice
Some Liquid Culture or Spore Solution
A Pressure Cooker
Preparing The Grain:
As we're using whole grain rice, we simply introduce the desired amount to boiling water and then cook for half the recommended time on the pack (Some brands a par boiled and cook much quicker....always check the pack!) Rice should be somewhat crunchy after cooking! Use the old taste test!!
Once the rice is cooked, quickly cool in water to prevent further cooking! Let the surface of the rice dry as much as possible.
Add the Rice to the jars and cover in foil. Place in the pressure cooker and sterilise for 2 hour to be safe!
Let the jars cool right down (I leave overnight) before removing from the pressure cooker.
Inoculate in your still air box!
Good Luck and Happy Growing!!!

It’s crazy how much they grow!

It's amazing that you can grow high-quality mycelium using just stuff at home! Your method is very helpful.

Yes! It always amazes and fascinates me when I get a healthy and rich mycelial growth

A paper punch like a single hole punch, or i guess 3 hole punches would work if it doesnt dent the lid... i just use the single hole punch for adding holes to paper for binder rings is perfect for 13mm injection ports for a friction fit and eliminates the need for glue. but i use mason jar lids that i can fit into thw punch

[@BigMush9000]

Good idea! I'm not such a fan of the friction fit though. With glue I can be 100% certain I have a perfect seal. The glue also prevents rust on the lids (I have no idea where I can find those plastic lids I see some growers use :D) Hole punch is a great idea though

@@BigMush9000 "Polypropylene (PP) and polypropylene copolymer (PPCO) containers can be autoclaved many times. Fluoropolymer products, such as Teflon PFA, FEP, or ETFE, can be autoclaved without problems." ... I still don't know if I like the idea of plastics but they do seem like a better solution... Altho rust is not an issue tbh but for you I guess making videos you want it looking presentable. The only issue iron oxide can cause is a bacterial contamination but it would only target the rust. PCing the rusty lids fixes that tho. There is 2 types of hard water, suspended iron particles and then the bacterial kind that starts with suspended iron particles. I unfortunately have the bacterial hard water so I had to learn aaaaaalllll about bacterial rust/iron rot. A little bit of rust isn't an issue, just for the peace of mind 👍👌

@lukeblizzard5909 Thanks for this mate! Im still relatively new to all of this, so I'm very grateful for your advice. Cheers man!

Best temperature for colonisation ?

[@BigMush9000]

@gizmorepairs anywhere between 18 and 25 or so Celsius works pretty well I try and keep colonisation temp on the lower side. It's slower for sure, but certain spores and things germinate at higher temps. I usually aim for 20c. This of course depends on the particular type of mushroom you wish to grow ;)
