Average Yields on Poo/Straw
    #5020840 - 12/05/05 10:56 PM (18 years, 5 months ago)

For you old hands, I was wondering if anyone has determined a rough estimate of yield per mass with cubes on poo+straw casings. For instance, if afoaf has 10 lbs of 50/50 colonized with penis envy how much might afoaf expect to harvest dry given all the conditions are correct per Sir Stamets... that's right, I knighted him! Fuck, Elton John got it... that is horseshit (with no goodies on top)

200 to 250% B/E isn't unheard of, in experienced hands & optimal conditions.

I'm not sure what B/E means? Did you mean like 200-250% more than on cakes or what? I think the person who is wondering is very consistent by now in the PF teks and has a nice, controlled setup but not particularly familiar with bulk substrates. He was just trying to get a feel for dry yield expectations per pound of poo straw mix.

I dont weigh wet, but I get 1oz dry for every wet lb of substrate. 5lb bin should pull at least 5oz dry

"200 to 250% B/E isn't unheard of, in experienced hands & optimal conditions."
Would this be considering the substrate in its dry form or wet form (makes a big difference :wink:)

the substrate is 9.81 lbs wet, so maybe... 7 lbs dry? I'm not sure the dry weight. But is it actually possible to produce 20lbs of fruit out of 10 lbs of substrate? Wouldn't that be like making something out of nothing? Although if it happens I won't complain :smile:

I was asking agar what you use dry or wet weight in the calculation :wink:
But not really creating something from nothing.  If you look at that more closely, you are using 10lbs of substrate, and getting 20lbs of shrooms.  But they are 90% water, so you are actually only gaining 2 lbs that is not water.  And some of that weight might come from other respiration processes (carbon fixing, I doubt it; but don't know enough about fungi to say)  So I would guess that they are using the dry substrate as the reference for calculations.

It is all relative. You can define the BE according to dry mass or wet. Using a compost moisture coversion of 4:1 wet:dry and a fruit moisture conversion of 10:1 wet:dry, 10% conversion of dry substrate to fruits is equivalent to 100% BE.

Ok I think i get it now, or maybe not. A 4:1 moisture conversion would mean that 10 lbs of wet substrate would be like 2.5 lbs dry substrate. .25 lbs dry fruit would be a 100 B/E. So If youre saying I could possibly see a 200-250% B/E then I may be able to get 8-10 dry oz, correct? I swear, I learn more on this website than I ever do in class.

Quite possible under good conditions.

A 12 quart tray (wbs spawned to h/poo (or compost)& Ph balanced cased) with about 3.5 inch substrate depth & over about 3 flushes....under optimal conditions often will result in more than 1 lb dry net weight.

close, it is 2lb, since the ratio 4:1 means there are 5 parts 1 of which is dry. 4:1 sounds very wet to me.
you can mix most grains to a 100% water addition. So 1kg of rye grain will mix with 1 litre of water, giving 2kg of wet grain which will give 2kg of wet fruits at 200%BE. Most get a 8% dry content so that is 160g dry from 1kg of grain. BUT the grain itself has a water content of about 10% so really the 1kg starting grain was 900g so at 200% BE it will be 1800g which will dry to 144g.
So you are getting 114g from 900g of bone dry substrate.
