coir/potency/straw as a nutrient

hey there, i think i'm going to try this tek out...
i've heard that using coir will tend to less'n the mushrooms natural potency...given that i'm using straw and possibly using the coir as a casing layer will it still have the same effect on the mushrooms, or does the straw give it the nutrients it needs to be potent as possible.. plus, what is lime flour for, does it carry nutrients, or what is pH exactly?

pH is a measure of the acidity or alkalinity of a solution. The letters "pH" stand for Potential of Hydrogen.

There is nothing out there that states coir will lower the potency. Coir is a great substrate. Not to be used as a casing layer. Casing layers are for moisture control. (no nutrients).

I think the original poster may have read something about how coir, as a substrate, will have less flushes than compost or manure based substrates but in terms of potency, there is none.

Potency is not a function of substrate. Coir is just fine, as is manure, straw, compost, worm castings, coffee grinds, etc. RR

well, researching throughout a few posts on here, i have come past others saying that coir, without the amount of nutrients that manure/ straw and other material has, The mushrooms will come out less potent. Not saying i read accurate information, but i deffinately read it.
also i forget to say i was doing shroomgods straw tek. i don't need to hook up a humidifier right, just misting is fine? and do i keep the humidity up while the straw is colonizing, misting..or is the humidity change when put to fruiting significant to change.

So a cheap and easy way to fix that is to go to starbucks and ask them for coffee grinds (they're free). 80% coir to 20% coffee grinds (adds nitrogen to the substrate which will produce more flushes like poo does). Add some hydrated lime too, it will raise the PH making the sub less acidic, less prone to contamination.
Doesnt really matter what you case with as long as some lime is added to it. I think im going to do a MGMC 50/50 with verm for my casing should be pretty tight assuming my tub doesnt start pinning early (would be cool i'd get fruits quicker, but less of them only the 2nd flush should be better when I case it.
but yea im tired of hearing about coirs potency, i've eaten fruits grown off coir and they were just as good as the rest. But in later flushes I've heard potency drops due to coirs low nitrogen content. Its kind of like making a poo-like substrate without the hassle of buying expensive poo online or collecting it in a field of something. plus the coir is pretty easy to pasteurize. Iduno I've always liked coir as a sub so I'm gunna go all out eventually and see what it can do if the right nutes are added in.

coffee grinds and hydrated lime, sounds good...you can find hydrated lime in gardening supplies right? lime flour as an alternative?

That's good, and the fact that you questioned it again in a public forum is awesome... I give mad-kudo's to people who don't except what they read as fact.
The archives in this forum are invaluable, but you have to realize that there is a lot of very ...well intentioned... misinformation and superstition that circulates as new people come on and post what they believe they understood from an article/tek they just read, but have not done themselves.
I'm still occasionally guilty of it - hence my sig at the bottom - but I take my lumps for it. Just remember "he who teaches is twice taught" because having to explain what you understand to someone else, in a way they can understand it, really cements it into your brain.

Coir works just great all by itself for me. I quit drinking coffee, so I quit keeping it on hand for my mycology experiments as well, and I have not noticed a difference between 10-20% coffee/coir and straight coir.
Also, leave out the hydrated lime...There is no need to adjust the PH, so no need for the lime.

Not to question you, but can we get a few more opinions on the addition of hydrated lime?

Depends on how much coffee you add since coffee is slightly acidic if you add a shit ton then you will have to add lime if not then there isnt a need for lime.

Using WBS as spawn, then using an 80 coir / 20 coffee grounds as substrate, how many parts lime should I add?

Used coffee grounds aren't really acidic. The bulk of the acidity gets washed through during brewing and goes out of the grounds & into your stomach.
Is there really a need to add lime because you use used coffee grounds?

are we talking about used coffee grinds, or fresh beans thrown in the grinder than add to the coir and pasturized/ i'll have to try the 80/20 coir/coffee...with maybe a dash of lime, but theirs probably no need
