Well i tried a little experiment today, hydrating sawdust with lime water and then inoculating with phoenix oyster without any other means of treating the substrate.
My process was very simple: -i measured 4 gallons of sawdust, (or 2512g in my case) -calculated how much water to add in order to bring the end product to 70% water and 30% sawdust. (about 5800cc H2O) -added 50g hydrated lime to the water. (probably too much ) -Mixed the sawdust with the water (added 2 handfulls of Gypsum) -let the mixture sit for ~18 hours -inoculated with grain spawn. -pray to the mushroom gods
Inoculating:

I've been doing lime baths for a couple of weeks now and noticed that GGMM is wrong on the lime recomendations. Stamets says most people use 2-4lbs per 55 gal drum. According to my calculations the maximum solubility for Ca(OH)2 is around a pound per 55 gallons. Just putting that out there. I still have dregs at the bottom after adding a pound, you'd probably have to mix like a mofo to get it all dissolved. Or maybe my water's just not 20-25C.

I just wanted to add that depending on where you are at and the quality of the straw it is a good idea to rinse the straw off before the soaking. Just a quick rinse of the hose. I have a tub unit that showers the straw continuously until the lime water is absorbed. I run clean water through it first for a little while-drain- and then add my lime solution. Sometimes straw can have lots of dirt and crap all over it even if it doesn't look like it. This can help lower contamination issues. Edit: I just realized you are using sawdust.. Still works but you have to measure the lime and add it to your pre-determined amount of water.

Damn nice recirculating system, Lipa. What size is that tub? How much straw will it hold?

Love the professional set-up!
I wonder what the benefits of pumping the water around would be? Cleaner end substrate...needing lower inoculation rate..?
I've only done one proper trial of the straight lime soak (no shower) and it's 100% success. Zero contam, colonised in 8 days!
And I've been trialling re-using the lime water, so far it's looking really promising!
Any thoughts lipa on the need for the pump lipa?

lipa what brand of lime do you use? I have found hydrated lime(this is for the garden) and dolomitic hydrated lime type S(this is use for cement). I live in northern California and this is all that I have found so far.

I concur the GGMM ratio is far too much. I use about 400gr for 200l (that's 4x drums) and get ph14 to start

It's nice because you can use a pre-determined amount of water and lime (actually a little more so the pump keeps running). There is no waste. The left over solution can just be added to the next batch. The shower gives for a very nicely hydrated substrate. No excess moisture issues.

The type s lime works with some oyster strains I found out in the beginning when I first started experimenting. Some will just stall to a halt with it. It is best to go to the garden center and look for hydrated lime that has a very low magnesium content. This works the best. I just get whatever I find. Some large nurseries carry it in large bags. I don't remember the name of the brand I used. Its been a while.

What do you consider "very low"? I can get Lee Double Strength Hydrated Lime in 50lb. bags at the local feed store for $7.99, but the Elemental Mag. content is 17%. I'm not real sure what the range is or where this falls on the scale.
P.S.: I think HT_AlohaMed just answered my question in another thread, although he was talking about CaCO4 supplementation, I would think 17% would be far too high for lime. Opine?

i'd steer clear of that since it's a mix of calcium and magnesium hydroxide. it was what i bought first on accident. There's like 6 different kinds of lime at the co-op here. Agricultural lime is calcium carbonate and hydrated lime is calcium hydroxide, imagine the looks I got asking for calcium carbonate and calcium hydroxide! A cement supply may be a good look if you can't find it otherwise.

Hey Lipa do you mind describing how your system works? The garden hose brings in fresh water, and the drain goes into a drum and a pump just brings the water through the hose back into the trough?

Lol peeps get so granular with their designs. I just hydrate my straw in a bin overnight. Sit it out in a homemade strainer for a couple of hours.
Shrooms are not hurt by dirt...
I then sterilize my mycobags for 2 hours each.
Works fine every time.
