BIG BREASTS, B/E, substrate size & types
    #5388657 - 03/11/06 09:43 AM (17 years, 10 months ago)

B/E stands for "biological efficiency".

An example of 100% B/E is this.

1000 grams of fresh mushrooms
derived from 1000 grams of dry Substrate
is 100% B/E.


P. Cubensis is quite capable of 200% B/E, under optimal circumstance.

People often ask why I shout out.

Do grain spawn, to bulk substrate, cased.

Here is why.

Standard PF type cake recipes only contain X amount of DRY weight BRF nutrient, per 1/2 or 1 pint cake.

A bulk substrate like dry compost, or h/poo spawned with wbs/grains is nearly 100% nutrient.

Figure it out YOURSELF. As an example.

Calculate the DRY weight of BRF that goes into 20 1/2 pint cakes.

Then, compare the B/E at 200%, with bulk substrate.
(which gives PF cakes B/E the benefit of doubt).

Calculate the B/E of 10 lbs of dry weight compost, or h/poo.

Post your answer.

The numbers speak for themselves.

The formula for biological efficiency has always kinda .... Bothered me I guess I could say.

I just don't understand how something can be more then 100% efficient.

Wouldn't it be more accurate to use the dry weight of the mushrooms?

Probably a very simple answer to this but I'm just not seeing it.


edit:
I just pondered this for a few more minutes and started thinking, I would suppose this calculation is used by commercial mushroom farmers who grow legal edibles. Drying them out would not only be a time and money consuming job, but no body would want to buy cracker dry edibles.

I think I did the math right=

at 200% BRF's B/E at 20 jars is:
3.32lbs= 1511.974grams
and the horse poo's B/E at 100% is
10lbs= 4535.927grams

it certainly does speak for itself... asssuming I did it right

but doesn't that just come out as simple weight nutrients?

ITs only advantage is that its coupled with another nutrient, bird seed making it 100% nutrient as you say

So the B/E is lost due to the fact that PFtek uses Vermiculite as a conditioner and loses net weight as it doesn't add nutrients. Where unless you tripple the size of your incoulated jars your still really wasting more spores instead of up and using horse poo instead.

how is 200% efficeny even possible, can a colony turn 1000 grams of nutrients into 2000grams of shrooms?  :confused:

casing is the only way I can think of but even then the best it can do is 100% off the top

yes... but this is DRY weight.

dry the 2000 gm. and see what you will get.

well, its calculating dry substrate- I doubt the dry substrate/dry fruit ratio is 1:1 in this case with 100% B/E-

or is it? To my understanding dry fruit is 1/3 its wieght when wet

Dry substrate weight = wet fruit weight for 100% so Dry weight/10 = dry fruit weight.

Think about the water (moisture).
After all, a mushroom consists of 90% moisture.

Calculate the B/E of 10 lbs of dry weight compost, or h/poo.

Post your answer.




Is this extra credit for the hunt? Anyway, BRF has a specific gravity of .593, or 1.62 pints/lb. Since twenty 1/2 pint jars equals 10 pints, you start with 6.18 lbs of flour and yield 12.36 lbs of shrooms, at 200% BE. 10 lbs of horse poo at 200% BE yields 20 lbs of shrooms.

Another way to look at it is to start with the same amount of dry substrate. Since there are 1.62 pints/lb, it would take 16.2 pints of BRF to equal 10 lbs of horse poo. That is 32.4 1/2 pint jars of BRF. Each 1/2 pint jar would need to produce .62 lbs of shrooms to equal a crop from 10 lbs of horse puckey.

[EDIT:] corrected typo from lbs/pint to pints/lb.

Mogur, are you accounting for the fact that 1/2 pints are not totally brf?

No, the actual number of jars would have to increase to contain 10 lbs, by the percentage of unused jar volume.

[EDIT:] For 20% unused space, the results would be 39 1/2 pint jars, and .513 lbs required from each cake.
