hydrated lime
    #18847994 - 09/16/13 07:52 AM (10 years, 4 months ago)

So much has been written on it and i've yet to experiment it. Does it also work for Golden and blue oyster? And does the solution also will be good enough for the other substrates like corn cobs?

Hi there,

I see you are working with lime. Remember it needs to have less than 2%Mg for mushrooms. It will work great with both blue and Golden oyster. I would suspect you would need to chop up corn on the cob pretty well to prevent high contamination rates. Corn cobs have a lot of nooks and crannies that the lime solution may have trouble penetrating because it is such a tight squeeze. Good luck! if you need a place to buy the correct type of lime for the best prices please feel free to contact me or post again. I am active on this forum on Mondays, but you can call or email me at the website in my signature. Good luck!

here's a brand you'll likely see at your retail nursery centers.

as stated, low low magnesium is what you want.

good luck

Since, I've a lot of rice bran, will soaking it altogether with straw increases yield or will contamination rate be high?

Thanks.

This could potentially increase your contamination since rice bran has many nooks and crannies that may be difficult for the lime solution to penetrate. I would suggest autoclaving the bran for best results, but maybe if you stir up the rice bran/straw solution really well every couple of hours so that the whole thing gets really good and mixed and all surfaces are exposed to the lime, it may not be too bad.

You could maybe accomplish this with a concrete mixer on low speed.

So I've yet to do any research on lime at all, but I noticed this thread was active so I thought Id pose a question!

I have access to large quantities of bags marked 'Food Grade Calcium Hydroxide (Hydrated Lime)'. I'm free to take a couple of pounds periodically if I like, as where I'm at we periodically end up with half bags we don't use. Sounds like the right stuff to me, although I don't know what it says for Mg content... What do you guys think? Free food grade lime too good to be true?

it may be...but probably is food grade/water grade which means 99.9 purity maybe?  i think you're good to go.

Which begs the question. Anyone ever tried the hydrated line trick in pure sawdust?  I think it would difficult (impossible) to get it back down to carrying cap. Without a big ass press of some sort. Allowing it to dry a bit over time would likely re expose it to mold spores.

I have been re-hydrating straw and wood fuel pellets plus dried Alfalfa with a saturated lime solution by adding exactly the correct amount to a filter patch bag, leaving to hydrate then inoculating with grain. So far only mould with Eryngii but going to try and double the spawn rate and see where I get.

I also have been very curious as to how well hydrating the sawdust w/lime water would work.  Any yield or time comparisons to sterilized sawdust?  Once i can find some lime im going to try this too.

Yes.

I've never been fastidious with moisture content, mushrooms grow regardless. I'm not a commercial grower, so I can afford to be experimental. I just put sawdust in a bin, dissolve hydrated lime in a bucket of water, add it to the bin and top up with water. I use a canoe paddle to mix it up, then leave from between a few hours to a few weeks. When I want to use it, I tip the bin over, lid on, and allow it to drain. Then I bag it up (or buckets or boxes). I also mix some in a cement mixer with sugar cane mulch which has been similarly treated.
I've fruited king/white/blue oysters, shiitake, agrocybe, enoki and shimeji. Colonised with reishi, but too cold, waiting for summer for fruits.

Nothing yet just started with the in bag lime hydration. I have never yet been able to grow Eryngii indoors on a lime soaked substrate. I know it can be done as others have posted. I am experimenting with both lime and Alfalfa.
