Oh and Hallucinogen, sorry to correct u on this but I think he meant he had half of his SUBSTRATE left off, not half a jar.

Yea, I had half of substrate left to fill another half a jar, its not that hard to measure.

 He is saying he had enough substrate for 24 jars not 12. He either packed them ungodly loose, or he made to much substrate.

maybe he was mistaken half-pint jars for pint jars... or vice-versa.. something of that nature?

each time i tried the pf tek id get left over substrate, even when i follewed the recipe to a T. no problem really, just put it into some more jars

the reason is plain and simple....the original PF tek called for packing the jars (go read) we all know not to do that anymore,dont we?

Yeah, half-pint jars = 1 cup. If you followed the substrate calc, it doesn't take into account the dry verm. layer on top. Add up what it tells you to use for 12 jars, and you get 12 cups. I changed the "cup" to 3/4 cup. It's 3/4 to the bottom of the threads (for the lid) on the jar. It's a bitch to use 3/4 cup scoops in place of 1 cup if you're making less than 12 though.
So for 12 jars we get:
Verm = (6) 3/4 cup scoops
BRF = (3) 3/4 cup scoops
H20 = (3) 3/4 cup scoops

the amounts called for in the origianl PF tek take into account that the substrate is packed in hard.
it has nothing to do with the dry verm layer which has always been standard.
3/4 would get you close but i'd put money on it being closer to a half,at the most it would be .6
packed jars will produce more/larger shrooms (like in the PF tek pics) but they colonise slowly and are more prone to contams/drying out and stalling.
a lightly packed jar will colonise much faster and tips the chances of success in favour of the newer grower.

Hmm, I may try a few packed down a bit next time.
It's not a half, I've tried that. 2/3 Isn't enough, but 3/4 is pretty much right on.
I just like to conserve my BRF, as I hate seeing the "Health Food Store Ladies"  , and they only carry 2 lb bags.

Are we still guessing for a p. azure print???
If so, I'll contribute my theory. If not...well looks like I'm contributing my theory anyway.
I think there are two factors at work here. The factors that increases the number of jars used given X cups of ingredients: The fact that the jars are not filled to the brim with substrate, and the fact that the substrate is normally loosely packed. The factor that decreases the number of jars: the fact that part of the water ingredient is absorbed in the vermiculite. So if 12 cups are used, 3 cups brf, 6 cups verm, 3 cups water, part of that water in a sense combines with the verm, so there are actually fewer than 12 cups of densely packed substrate. Also, the fine brf will fill in the relatively large empty spaces between the verm, thus not adding their full volume to the final substrate. This is why you have less than 1/4 of your original substrate left over, even though you may fill your jars 3/4 of the way.
My final theory is, the first two factors outweigh the last factor, so you are still left with leftover substrate, but not as much as you would be if you actually started with 12 cups of substrate. Since you start with, say, 9 cups of stubstrate (from 12 cups of ingredients), just fill your jars about 3/4 of the way full, if not a little more, but make it airy, so thus using even less than 9 cups of substrate, you will have less than/about 1 cup left.

We are still guessing for the print.
The calling for tamping down in the older directions is one part of the answer.

#1 the tamping down of the substrate
#2 whether its course or fine verm.

Butternut squash are softer than acorn or other types of squash, which makes them easier to cut and prepare.

Hey guys, I did use 1/2 Pint jars and a total of 12 cups of substrate. I didn't make any miscalculations, I didn't want to mess this up so I was extremely careful.
I was originally thinking that the reason was that the PF cake recipe was designed to fill the jars all the way with substrate. I guess they accidently combined the measurements for the dry verm layer on top with the verm that goes in the cake. Oh course not tamping down I'm sure contributed to the left over substrate as well.
I mixed everything slowly and carefully it wasn't my fault.
Thanks for the replies everyone,

I cannot recall the last time something like that happened in politics or religion.

1)Tamping down the substrate
2)water cause's the brf/verm to swell up making more bulk, like grains do

Well this may be stupid but here's my two cents on why it happens.
Say you doing the 2 parts verm, 1 part water, 1 part brf mix. Total that is 4 parts. Now say your measuring the parts with a half pint jar. Now a jar of pure brf is packed weather you want it to or not. There's you one part. Now when you get the verm I'm sure most would fill the jar but they wouldn't be all lightly filling the jar cause it's not a colonization worry yet.
Now you have your stuff all mixed up but now your putting it in the jars all lightly and trying to make it somewhat airy for the myc to spread. So if you have 4 jars of mix then throw it in a bowl and mix and then lightly fill the jars there will be some left over.
and last, when most are measuring the amounts for the jars they don't take into account the room needed for the dry verm layer.
