I don't use hydrated lime in any of my substrates, as far as I know/am concerned, the purpose of hydrated lime is to make the mixture as close to pH neutral if not just a tad on the alkaline side because very few (common) contaminates can germinate in that hostile environment. As an aside, it's also why we try to make the casing as non-nutritious as possible.
And our targeted mycelium don't like a pH neutral / alkaline environment any more than any contaminates would either but the idea is that after it's colonized the wonderfully nutritious and slightly acidic substrate it will have no problem powering through the non-nutritious and less acidic casing mixture to find it's way to fruit.

Using WBS as spawn, then using an 80 coir / 20 coffee grounds as substrate, how many parts lime should I add?
using that ratio you shouldnt need lime i was talking about if you are using somewhere around 50/50 is where the lime would come in since spent coffee grounds are about 6.5 ph. slightly acidic.

A substrate should have an ideal pH between 6.0-6.5, so that would be fine, without lime. Our mycelium, like most other mycelium, favor slightly acidic substrates to grow in.

thats good to know, i wasn't all for getting lime or spent coffee grinds anyways..probably just try casing my straw streight coir.. does straw contam easily? such a big project turning to shit, thats never a good feeling.
and when the straw is spawned/colonizing do i have to mist the sides and keep the HU/ up or is that just recommended when it hits fruiting stages after cased?

If using a high ratio of coffee grounds it would be more 4.0-5.5 ph which is very nice to grow some trich in.If that was the case the use of lime would be needed.Use a ph meter to determine where you are at.

SO can ANYONE tell us what is Potency a function of? RR your opinion would be also appreciated.
Far from having any evidence other than theory, i've come to conclude that your mushroom potency is decided before your spores ever germinate. The potency is likely decided by DNA, just as your own DNA tells your body how many skin cells to produce, the mushrooms' DNA tells it how much psilocybin to produce. Possibly, but unlikely, you might be able to get your mushrooms to absorb chemicals from your substrate such as tryptamine, but this is hardly practical. When using a multispore inoculation on something such as poo, you might end up with some exceptionally potent mushrooms, but this probably because they're grown in ideal conditions, provoking the growth of strong mycelium that fruits thick mushrooms. When you have thicker mushrooms you have heavier mushrooms and usually heavier mushrooms means you have more tissue and where you have more tissue you're likely to have more psilocybin versus less meaty mushrooms.

i would have thought smaller mushrooms because the psilocybin would be more concentrated and condensed... but it was just a thought.
anybody for misting sides of tub as straw colonizes before fruiting...or is this not a good idea?

i didn't say larger, i said fatter as in more meaty, like not hollow
