Auto-SummaryLiquid Spawning or Inoculant 2014, developed by TV Casualty, is a revolutionary technique for colonizing quart jars in just 3 days. The method involves creating a slurry using a small mouth pint jar, a pressure cooker, and a blender. The slurry is then used to inoculate multiple jars or bags of substrate. Key points include:
- Results: 3-day colonization of quart jars
- Materials: pint jar, band, foil, blender base, pressure cooked butter knife, black plastic base, colonized jars
- Procedure: Prepare utensils, sterilize jars, sterilize and set up work area, blend cake into slurry, pour slurry into jars/bags
- Tips: Use 1/3 to 1/2 of the pint jar for slurry, avoid shaking jars, fully colonized jars/bags in 3 days without shaking

Liquid Spawning or Inoculant 2014:
First of all, TV Casualty is the man who invented this. This has revolutionized mushroom cultivation and everyone needs to know that you can successfully have fully colonized quart jars in 3 days.

tombosley8 results: Thanks tom for ignoring the haters and trying something new.
 
My results: but didn't take picture of the 3rd day. Ive tried this over 20 times with great successful fruiting of substrates used with the same spawn jars.

PROCEDURE FOR JAR INOCULANT
Materials:
- small mouth pint jar
- band for the small mouth jar
- foil
- oster blender base and blade assembly
- pressure cooked butter knife wrapped in foil
- black plastic base for the blender attachment
- one colonized 1/2 pint pf jar
- as many colonized grain jars as you want up to 100: wbs, rye berry, popcorn
- optional: you can also use this on grain prepared in filter patch bags
- pressure cooked foil large enough to set a pf cake on. this is wrapped in foil
Reasoning:
Usually this method works well when you have about 20-100 quart jars you want to colonize in 3 days. If you are only doing 10 quart jars then you wouldn't need to use about 90% of the slurry because you only need a small amount per jar. I will then use another method like P2G for fewer jars. However, if your using a smaller quart jar number you can easily add less water to the mix and make the slurry more muddy. This will reduce the risk of adding too much water to each jar. You only need a small amount per jar. I would compare this to the equivalent of about a tablespoon of slurry per jar. You also need to be careful that if you add too little of water, the cake won't properly blend in the jar. I would say 1/3 to one half of the pint jar is a good ratio. 1/3 on the muddy side, 1/2 on the more liquid side with more jars.
Procedure:
1. Prepare your utensils in the pressure cooker. I wrap a piece of foil large enough for me to flip a pf cake upside down on and cut it in half. I then wrap that piece of foil with foil and pressure cook it with other utensils.
2. As you can see the small mouth pint fits snugly to the bottom of the blade assembly. Fill the pint jar halfway with distilled water and place the blade assembly and ring on top of the assembly. Twist the ring so it is tighter but not too tight. Then place foil over that. Now it is ready for the pressure cooker. Some people have issues with the plastic grey gasket that hangs on the blade assembly. Mine is so old that it pretty much sticks to the blade assembly and i don't have to worry. However, you can also RTV silicone this directly to the lid in order to make things easier. You want to make sure that the bottom part that is touching the jar is not siliconed only the top attaching to the blade assembly.
   
 
3. Place your butter knife wrapped in foil along with your other utensils(pint jar with assembly) in the pressure cooker. Pressure cook for 30 minutes at 15psi. Let it cool. Then you can begin doing the clean work to do the liquid transfer.
4. Now that you have all your utensils sterilized and your grain jars prepared. It is now time to setup your clean work area. In my case I use a Shmuvbox or you can use a floowhood or SAB. I setup all my jars to the far right out of the way so I have room to place all my utensils up front in the shmuv. This is so I can easily reach the utensils. I wiped all the jars down with rubbing alcohol prior to sticking them inside the clean work area. You can see my foil wrapped foil in the middle, my foil wrapped butter knife in the middle and the fully colonized pf half pint on the right. You will also notice the black assembly that attaches to the blade assembly for the base of the oster blender. I wiped this down with a bleach wipe prior to putting it in the shmuv.

5. You also want to setup your blender close by. I wipe the whole thing down from top to bottom with bleach wipes and even spray it with lysol.

6. Now you can prepare everything to ensure a quick transfer. This process involves taking off the foil and band lids to the pint jar or jars. You will also take the lid and foil off of your colonized pf jar. I place the items to the side out of my working area. But you can also take them out of the shmuv completely. Although if you remove your hands, always clean them thoroughly before placing them back in.

7. Now I am about to dump the pf cake upside down on my sterile foil.

8. Unwrap your butter knife and cut the pf cake in half. Now I am doing this because im trying a less slurry or muddy mix to see if it still works. You can simply use one pf cake and dump it upside down into the pint jar. This is a technique view of the 1/2 pint jar flipped upside down on the pint jar so that the cake slides right into the jar without touching anything. If you have to move the blade assembly be sure to set it face up not touching anything on the blade. You can hold it in your hand and flip the jar at the same time but you need to be careful not to touch it on anything. You don't want to introduce any contaminants into the jar.
 
9. Now if your using one pf cake for less jars. Simply flip the jar upside down shown in the previous step. Or if your making multiple jars for liquid spawn or liquid inoculant you can use your sterile knife to cut the pf cake in half. You have placed this pf cake on the sterile foil which you just unfolded. Work clean and fast. You then spear the side of the cake with the knife, open up the blade assembly touching only the outside and place the cake into the jar. You can position the cake so that you can simply use the cake edge against the inside edge of the jar to use as leverage to pull the knife out and the cake will drop right in. This takes about 3 seconds max.
 
10. Now I place my black blender attachment assembly on the top of the metal blade assembly. I clean the area so that when I am about to do the transfers, there is clear room to work clean and fast.
 
11. I now take the jar and assembly out of the shmuvbox but still in my cleaned work area and use the blender to blend the cake into slurry.
  
12. Now the slurry is ready to pour into each Jar or bag.
13. You simply bring your jar back into your work area. You have all your quart jars and bags with loose lids ready for transfer.
14. With one hand slightly lift up the blade assembly lid with your fore finger and you will then open the quart jar lid with your right hand. You pour about 1 tablespoon of slurry into each jar. The key is to quickly close both lids simultaneously after you do the quick transfer. This minimizes contamination.
15. After you have inoculated all of your jars and bags. You simply shake the jars for 20 seconds each. You want to distribute that extra water you poured into your grain jars as much as possible so that you don't have any issues after this. At first you will get a little scared because your jars will look like there is pooling water at the bottom once they have sat on the shelf a few hours. Be patient, wait it out. The idea is to have fully colonized jars in 3 days without a shake and it works.
FOR THE SLURRY IN A HURRY TEK DO NOT SHAKE THE JARS. THE KEY HERE IS TO HAVE FULLY COLONIZED JARS/BAG SPAWN IN 3 DAYS WITHOUT SHAKING THE JARS AT ALL. !!!!
