Biological Efficiency?
    #1968780 - 10/01/03 07:30 AM (14 years, 2 months ago)

What is the equation to figure out the BE of a particular strain?
the dry weight of substrate used is: 7oz (196g) popcorn, colonized and used to spawn 6oz (168g) poo (dry weight of poo before pasturization)

also is the dry weight of the substrate used the only variables needed to figure out the equation?

if i am missing important information required to do the math let me know and i will "fill in the blanks" so to say.

i hope all of this makes sence, thank you to all !  :smile:

I always thought total flushes dry shrooms over weight of total dry substrate = BE ratio. In millet (and for practical purposes) can be a 1:5

Mind you, total dry flushes can be pointless since you'd be running trays of stragglers, rather than new trays that are thumpers.

BE v's use of precious terrarium space real estate LOL

??hm.... try the advanced cultivation forum* :smile:
As far as I got what you are tying to say Anno is just trying to find out which substrate is best. Go to the Growlog Forum and check his Thread!

no, im not trying to determine which substrate is best, i want to know how much of the dry matterial  was converted into mushrooms. does this make more sence? 

when the tray made with 7oz (196g) popcorn, colonized and used to spawn 6oz (168g) poo (dry weight of poo before pasturization) is done with all flushes i am going to add the total weight of all flushes together,  after i have the weight of all flushes and the dry weight of the substrate used how do i figure out the Biological efficiency?

*...total flushes dry shrooms over weight of total dry substrate = BE...*

(that's food substrate as you've stated).

So, 196g + 168g = you 364g dry substrate.

Xg = total shroom flushes dried in sum gram weight.

Your BE will be...

Xg divided by 364

An impractical measure IMO since few will run trays to rediculous flush numbers like 5th, 6th & 7th flush when new trays will give so much more per area investment. Good for curiosity though.

Post back what your BE is when you're done, I'll be interested. :smile:

thanks for the help, the tray will be flushed as many times as posible, and i will post the results when it is finished

No.
The definition of biological efficiency in mushroom cultivation is:
1000 grams fresh weight from 1000 grams dry substrate is 100% biological efficiency.

P. cubensis is easily somewhere in the range of 200% BE.

    #1969160 - 10/01/03 12:34 PM (14 years, 2 months ago)

Ah so it's fresh weight Anno.

Is that the convention?

I have to ask, but what use is fresh weight to people when it can't be stored/transported?

It has to be of practical application since nearly every shroom grower will dry their surplus for later use.

The drying of produce and using that as a measure is nothing new. For example, in the HID Cannabis circles the measure is based on unit return of dry bud to the unit square. A good rating is 2.4oz or greater to the foot square.

Or the other measure is the GE rating. That's Garden Efficiency based on grams of bud to watts. A good rating is 1 gram of bud to every watt of input.

Needless to say, that's based on the fact that pot can only be stored/transported dry. I see shrooms the same.

Furthermore, drying shrooms can vary from 85% to 93% water weight to unit (in my findings) and can vary from individual shroom to individual shroom too. Only cracker dry is it a known unit quantity and IMO it's from that you could benchmark your BE rating.

Where did the fresh weight to dry substrate BE paradigm come from?

Edit:
Thinking about it, the wet weight to dry substrate BE would have application in licit mycology production i.e. A.bisporus, but not shrooms which street drug dry.

so if P. cubensis has a 200% B.E. does that mean i should get twice the dry weight of substrate used in fresh mushroom? provided that all conditions are optimal. i'm sry but i am getting confused.

It would mean if you used 500 grams of dry grain and got say I KG wet, then you'd have a 200% BE by what Anno is saying.

Now that's cool if you're down at the supermarket pitching them fresh (*i.e. licit mushrooms) where variations in moisture content are not an issue.

But you're not, you're cracker drying them because that's the convention of the street drug scene.

* yes I'm aware that cubes are legal in some countries, but for most on these boards (aka US) they're not.

anno's right. it's:

wet yeild / dry substrate mass

the term 'efficiency' is a bit of a misnomer for this i think... it's just mushroom jargon.

I'll accept that.

Though the paradigm would appear, would it not, to be set on licit food/gourmet mushrooms, rather than (drug) cracker dry mushrooms?

After all the shroomer folks (from what I've read and for good reason) are fixated on what they get dry.

thanks for all of the help i will post back soon with some results but it may take a while because im going to let it produce as many flushes as possible. GT strain is being used also going to start Malabar with exact same dry substrate weight to see if there is a differance in B.E. between the two strains (allthough i doubt it to be much if any differance) the Malabar test will take a little longer jars will be innoculated tomorrow.

once agin thanks to all! :smile:

Agaricus industry is where the term BE comes from, precisely.

Thanks Anno. It makes sense for Agaricus industry.

MESCALATO, good going on your project. Use PGP to set up grow a diary. Safer that way. http://www.overgrow.com/growfaq/1551

No offense, but why do you wanna know that?
Then you would have the "biological efficiency" of popcorn/poo of one tray. Which is not highly representable , as you are the only one testing it, with only your exact specs. (For instance "poo" is not just "poo", and "fanning" is not just "fanning") Aborts ,which are also "biological matter" are not taken into account either.
If you wanna hear my view: Your casing can get as little as my yield and as much as Joshua's. The truth is anywhere in between and not to be determing absolutely, but relatively.

wtf?....
it is called curiosity. also by doin this experiment with my specs. i will learn more about my techniques , say i end up with only 100% B.E. then something is wrong or could be better as Anno stated P. cubensis has a B.E. rate of 200%

also i don't realy care if it is only going to show the B.E. of that one particular tray atleast then i will know how efficient that one tray was.
