limestone flour, horticultural lime, p.h. balance question
    #14507512 - 05/24/11 11:16 PM (12 years, 9 months ago)

I saw THIS tek which includes 'limestone flour.' Is that the same as horticultural lime? If so, don't we want a higher P.H. cause it fights bacteria but the, shrooms can still colonize? Also, doesn't horticultural lime lower the P.H. balance which we don't want?

So... first, don't case cakes.

Second, there's several kinds of lime. Horticultural lime = hydrated lime, which is not limestone and will burn your mushrooms. And you.
But if you don't case cakes, it doesn't matter.

All those old casing teks were invented by people who weren't fruiting properly.
If they had known about the shotgun fc, they could have had better yields in less time with less risk vs casing cakes.

ok thanks. I wouldn't case cakes. that was there own stupid idea. I was just wondering about this horticultural lime
I've got laying around here. Someone gave it to me for my tomato plant fertilizer.

Well, it's hydrated lime (most likely). What's the magnesium percentage?

Shouldn't we consider the roll in verm to be the application
of a casing layer?  Just a thought.

OP, we use lime to raise pH and gypsum to stabilize pH.

Be careful with the lime though.  Do you have a pH meter?

Good luck,

JD

no P.H. meter thats why I use distilled water for everything. Except one batch of WBS which didn't go so well.

Well, I am still looking for hydrated lime (I refuse to
pay to ship it) and so I will hope that others will chime in,
but I can say that it is an intense base and very little
should be necessary.

I would use none rather than risk over doing it.

Take care,

JD

Technically yes, but you would not case them with casing material containing lime.
And most people here would tell you straight verm isn't good for casing, though it is.

JD, where are you that there's no lime?

Horticultural lime can be anything from limestone flour to dolomite limestone, hydrated, etc.

Hydrated lime is preferred.  It doesn't burn mushrooms.  It raises pH when needed, which is rare considering that mushrooms prefer an acidic substrate. 

If one is going to build a casing layer, hydrated lime is superior to the others which don't break down fast enough to alter pH during the short lifespan of a cased substrate tray.  Hydrated lime will dry your hands if you rub it all over you and don't wash it off.  Anyone who has mixed concrete or mortar mix and got some on their hands have experienced this, since it's very high in hydrated lime.

Thanks for the clarification RR.

Hey Doc, I am in So. Cal, but checking the Home Depot, and
then the local nurseries just has not turned up any lime.

I got a box of pelleted garden lime, but it is definitely
not the strong stuff I want.  I did get a Kellway pH meter
and so I will get my casing layers right.

IIRC, we do not want our casings to be very basic, but
maybe a point above neutral.  Wasn't 8.0 the goal?

I know that this is higher than mushrooms prefer, but it
is something that they can deal with, and it helps prevent
or slow contams.

Take care,

JD
