Pretty simple, I use the Pressure cooker without the lid for a big pot, I use a candy thermometer to monitor the temps and keep it around 165f. The big quart jar is filled with water to weigh down the wormcastings I have in that freezer bag. This keeps my castings from turning into mud as many other people have told me.
The tray is divided into 4 separate equal components. 1/4 Alfalfa, 1/4 coco coir, 1/4 wormcastings, and 1/4 Colonized wild bird seed. Their are five total layers. 3 bulkstrate layers and 2 colonized spawn layers.

The alfalfa straw and coco coir are both pet store bought. Brand name of the alfalfa is LIVING WORLD and the coco coir is Bed'A Beast, both bought at PETSMART: Land of animal exploitation.
Here is the filtering system. 2 bottled water jugs, 1 with the neck cut off so the other fits inside it, and the other has the bottom removed. A thick wad of polyfil is stuffed into the top jugs lip. Water rushes through polyfil like its not even there.
Unfortunatley the success of the filtering filtering device prompted my cocky nature and I overfilled the top jug and spilled the contents all over the dirty kitchen floor..... What to do? Guess it's time to stick the the stuff back in the pot for another 2 hours to completely pasteurize it again. I omitted the worm castings though and stuck them in a sealed tub for when I was ready to use them.
K here is the mix in the pot without any worm castings added yet. I just added it and mixed all 3 bulk substrates together by hand.
This seedling tray has roughly a 20 pint/10 quart (water) capacity. I measured this out by counting how many pint jars of water it took to fill the tray to the top.
K here is the first bulk substrate layer added to the tray. The way I measured it out was this: I have 3 bulksubstrate layers to add therefor I must divide it into one thirds 1/3's.
Here is the first layer of spawn added. 2 layers so we use half our spawn this time.
And here is the second layer of bulksubstrate added, again 1/3. Then the other half of the spawn and finally the last 1/3 of bulksubstrate to cap it off.
Hehe! ok this is pinning quite nicely indeed. The addition of alfalfa this time is definetely affecting the yield in a most posetive way :loveeyes:.
i actually think its (know actually hehe) the additiives used in the processing of the bedding that keep contams at bay. thats kinda where i was going with the 'possible contam-free sub thread that nobody has responded in but me yet :D :lol:
