Prof_P's Bulk Poo Tek 9

Preparation of a Perfect Bulk Substrate: The Prof_P Bulk Poo Tek
This recipe is meant to fill one clear 64 quart monotub to an approximate 4" Substrate depth.
Ingredients:
- ½ brick coir - 2 cups pelletized gypsum - 2 quarts COARSE verm - 2 lbs (~7liters) field aged h-poo - 3.75 quarts H2O (approx.)
  
Tools: - 1 power drill w/ drill bit. - 1 tape measure - 1 five gallon bucket - 1 butter knife - 1 qt. mason jar
  
Preparation:
Step one : Measure to 4 inches, which is approximately the middle, of the brick of coir and scratch a line dividing it into two equal halves. Take your drill and drive a hole directly through the center of mass of the brick along with another above and beneath it. Now press the brick up against the edge of your sink and snap it in half. It should break easily with its center of mass drilled out. Peel ½ of the brick of coco coir apart into thin layers with a butter knife, it comes apart very easily; then break into little pieces. Put them in the bucket.
  
Step two: Add 1 quart of hot H2O to the bucket and wait a couple minutes.
 
Step three: Break up the coir with your hands. Make sure to get all the fine chunks broken up really well.

Step four: The coir should be fluffed up and damp at this point but not wet. Now you want to add your 2 cups of gypsum and distribute it evenly throughout the bucket of coir. Make sure to mix deep.
   Note: It would not matter if you added the gypsum last, gypsum is water soluble, but I prefer to add it as the second ingredient in order to make sure to avoid clumping.
Step five: Add the verm. Mix well
  
Step six: Add the poo. Mix well
 
Step seven (The lucky step): Add 2 more quarts of H2O. Mix well. Make sure to dig your fingers all the way to the bottom of the bucket to get any dry areas hydrated.

Next add the final ¾ quart H2O in ¼ quart increments checking for field capacity along the way.
 
Now your ready to pasteurize and spawn.

Here is a link to a video guide of this tek,.....

No the poo isn't more prone to contams.
Actually coir is a 1 flush wonder. What I mean by that is I have tubs w/ straight poo get 7 flushes before going green. Coir, you'll be lucky to get 2. So in this sense it is coir that is more prone.
Gypsum is there more to aerate the substrate than provide nutrition.
The nutrition comes primarily from the Poo.
This is why I use 1/2 & 1/2 . It allows me to get more flushes because of the addition of the poo. Just a greater overall yield.
------------ Edited to add Pic ---------------------- Here is a Pic of a tub of PE done with this recipe that just started pinning.

I have a zero % contam rate w/ this recipe.

This is a more expensive model.
They have cheaper one at walmart.
You need the 18qt. one so you can fit the 4 bags.
Keep in mind its a steam bath method.

Thanks for the recognition!
The fluffiness this recipe allows for the substrate 1. increases colonization time due to increased aeration & 2. allows a better pin-set due again to increased aeration.
The proof is in the pudding, as you have seen with the Peener trilogy. For that grow I used this exact substrate recipe
I used to use these little mini bales .... I used to pick them up at Micheal's Crafts.
They were about 5 bucks a pop, came pre-shredded, bound by wire.
There are endless possibilities of additives that can be included in this recipe for sure....
I myself don't like to deal with the straw though.... only because I have found it to be a pain to deal with if your making a lot of tubs. I don't know why but I manage to make a serious mess in the house with it every time I even look at it. 
But like I said there is definitely a great array of things such as, worm castings, spent coffee grounds, wheat straw, kelp meal, etc.,,,,,etc.,,,,,,
Skys the limit if you have the materials, time, and patience. 
I'M JUST HAPPY TO SEE THE TEK BEING PUT TO GOOD USE... any further experimenting/modifying it is encouraged. I'd love to see the results people have when adding various additives to this recipe.
Good Luck & Keep Me Posted! .......

Yea, The poo generally provides enough nutrients. Coffee grounds are known to contaminate easily. 
These were done with just coir/poo/verm/gypsum.

This is good info 
Point taken.
These are the specific bricks I use.
 eco earth zoo med coco coir.
They are 8 inches long. If you cut at the 4 inch mark it is ~3/4 of a pound.

Ha, I just was talking about that on another thread....
I'm going to cut and paste a little something to save myself some time here .....
Bear with me [ ] I tossed a quick reference answer under the quote if you dont want to read through all of it.....
Quote:
ProfessorPinHead said:
The saran wrap seals the top to help retain humidity and the Polyfil both helps retain humidity and allows filtered gases to exchange during colonization. This helps reduce the likelihood of contams entering.
Here is an example. This tub colonized all the way from 0% -> 100% under an ambient light cycle with nothing but Saran wrap, polyfil, and a 30 gallon black trash can liner under the substrate.

.... No outer bag, no duct tape!!!!! THIS IS OUT OF DATE MISINFORMATION!!!!!!
 
I know there are a few different opinions on this one going around to date.... This process takes fine tuning to get down. I have been doing it for years and this is what I have learned to be true. I am a scientist and hold a research degree from a major university. I have been cultivating fungi since biology class during my undergraduate degree. This is my advice......
Do with it what you wish 
-prof.
Anyway, a quick reference answer .... ANY old Black 30 gallon trash can liner will do. I get mine at Home depot ( the cheap ones) for 4 buck / 40 bags .....
For any noobs reading this; asking themselves .... We use the black liner to keep light out from under the substrate and to keep our growth medium clean.

And when your bulk substrate is spent, you can use it to fuel these fuckerz!

ProfessorPinHead said: Yea, once its at 100%, Saran comes off, tub gets misted once / day. 
At this point we want evaporation of the substrate off the surface area and high FAE rates so as to trigger pinning.
FAE is the # 1 pinning trigger.
Thanks. I'll definitely try this polyfill/saran wrap way next & update this post with my outcome or reference yours on my own post.
I used your opinion on my Coir brick/verm/gypsum/coffee grounds & it seems to be working great. The tub I PMed you with only a few was my fault mainly, but there are two HUGE PE porkers that came out. I want to clone them.... I've read that poking syringe through middle of one & squirting the inner flesh into a LC type jar of Karo would do this?
-EDIT- Pic of HUGE porkers:

Used this recipe... tweaked the water content.. added earthworm castings.. pasteurized for 2 hours and I don't care about side pinning haha.. Wherever the mycelium wants to fruit is just fine with me.. frees up the top layer for the second flush..
MS Treasure Coast - Over 6 oz. first flush

Pinning started up all over the top layer two days later, and I can already tell they're gonna be some monsters.. Enjoy.
Nice recipe, Prof. P
