100% BE | Dry to Dry

In my examples I am using fruit body water content based on oysters, which is 90%.
Lets take a look at how BRF gives 100% or close to in yield.
To get 100% yield from 100g of full performance dry weight I need 900g of water. This is 10% dry weight and 90% water content, a fruit body.
Made up recipe:
> 20g dry grain flour. > ?? Amount of verm. > 180g of water.
As you can see in my example I am not measuring the verm, its used simply as body. However you can see I have enough water content to get 100% from my 20g.
This is 200g of total yield, where 200 / 10 is 20g dry.
Now lets calculate wood pellets.
Wood pellets have a knack for not holding water very at all, so the calculation is impossible. At 66% water content I would only achieve 100g dry per 500g dry, one fifth (1/5).
100g dry + 900g water, full fruit body, but never 100% BE.
Edit: Renamed thread, dry to dry.

The difference is your definition of BE. The growers on this board are using lbs of wet mushrooms to lbs of dry substrate.
Example 3 lbs of fresh mushrooms grown on 3 lbs of sawdust and bran = 100% BE

If I have a substrate with 100g fully usable dry weight and 900g of water content. I get 1000g of fresh mushrooms, that's 100% of my total substrate weight.
How do you get 200g dry weight from 100g dry weight (200%).

Because no one does dry matter of the mushrooms. Mushrooms are for the most part are sold fresh.

Sorry I know, but that is the gauge for production on the Shroomery. Mostly because it is a simple calculation. If you try to change , it leads to confusion.Its not inaccurate if everyone is on the same page.
"How do you get 200g dry weight from 100g dry weight (200%)."
They don't , they get 200 gr wet mushrooms from 100 gr dry substrate.(200% in Shroomery terms)

It doesn't matter I guess, just makes calculations a bit illogical more me. That mean's that I'm getting 200 - 250% from my WL-Tek.

Look in the glossary for the Shroomery.
"Biological efficiency - The definition of biological efficiency (BE) in mushroom cultivation is: 1 pound fresh mushrooms from 1 pound dry "
I know when I read your post it is confusing to me.

It's easier for us that actually grow for a living to compare with something easier than BE. So we use yield in terms of wet weight mushrooms/wet weight sub. Since most people running blocks use 50-60% moisture it's usually just about half of "BE" anyway.
Thus thread is dumb. But that's just my opinion.

Yeah when someone gives me bag weight I usually just round off to half the weight as substrate. Im just tired of all the different confusing numbers being thrown around.

yea, its only a measurable number if you dehydrate, which very few of us do except for medicinals.

I was simply correcting illogical maths, if that is dumb then we are all doomed. Not my fault the calculation for BE is made up, and people still use it.
If it where correct you would not be using yield.

Well raw inputs out to yield out is all that matters, water is daym near free so doing wet to wet wouldn't be a good ratio for efficiency.

Ah no worries, I'll just convert to yield, I see water as essential as energy or nutrients. Where a correct ratio of water effects the performance of the total yield.
Mycelium can make energy from water and carbon.

mycelium can also make water from Wood (hydrolytic rxns) and take water from the air . which is one reason why no one would ever grow in a 90% water media.

Hydrolysis usually means the cleavage of chemical bonds by the addition of water. Not the production of water. Water uptake from humidity is minimal, and will not hydrate the center of a substrate.
Humidity is to prevent drying out where the air is at full capacity.

Water uptake from humidity might be minimal but you should be misting, allowing moisture to be absorbed. I havent done a study but i bet my blocks weight slightly more when ready to harvest vs when they went in, granted they were misted properly.

No argument there Gr0wer, I totally agree that adding water increases the total weight.
However misting produces issues of its own, not all types can be misted. Secondly it disrupts nutrient uptake, if less water is taken up.
Like adding water to your blood stream.
Here is the heavy rain effect:
