Lime soaking straw

Ok. I got some high yield hydrated lime as pictured in Aloha's hydrated lime walk through. I see nothing about using soap. Does that mean soaking in soap to ensure hydration as you would when heat pasteurizing isn't necessary? I've read that this lime method with no heat produces better fruits than heat pasteurization but it doesnt talk about heat pasteurization used in conjunction with lime. So I'm wondering if that would prove even better. I intend to soak for maybe roughly 20 hours in the hydrated lime solution if anyone has anything to say regarding that as well.

no need for soap with a lime soak... I'd aim for more like 16-18h soak with lime, you can inoculate it straight without heat treatment if you've got an aggressive oyster strain and use a bit higher spawn rate than normal (I use up to 10% and it's colonised in 7-10 days) It's a great tek!

Can you colonize cubensis too without heat pasteurization?
the lime will make the pH right so mold won't grow?
I've always been pasteurizing straw in my PC, but it's time consuming, and can't pasteurize much at one time
I usually don't use lime, and have had success with 3 monos with straw so far, no contams yet don't PC in clear water though, PC with the straw water

Well I did a mix of both. I didnt have the ability today to get it up to 150 or higher but I got it to around 145 with heat for an hour and will let it sit a good 18 hour or so after in the calcium hydroxide solution. I put about a cup and a half into 20 gallons of water or so. Hopefully it works. Tomorrow I will drain and add grain of a P. pleurotus that has had yet to produce sizeable fruits on sawdust.

This threads pretty comprehensive on lime soak tek
http://www.shroomery.org/forums/showflat.php/Number/18503977
I tried it years ago and failed, changed my hydrated lime to one of the "high calcium" and tried it again recently. Been getting 100% success with oysters (soaked over 30kg dry straw) If you can skip the heat treatment why not? Saves time, money and uses less resources...nice!

Indeed I too have been using it for a while now, About 40 or 50 straw bales now. Unfortunately it did not repel bugs and I had to throw many logs out. Back at it bug free now!

how'd you get rid of the bugs? Are you growing outdoors?

Do you think the lime in any way attracts the bugs? Also quick question. How dry do you want to let yoru straw get before you actually spawn to it? Since I will have holes in my bucket should i merely strain then add to bucket with straw and let it dry out as it needs?

i'm growing in a warehouse that is not really sealed off, but my grow chambers are pretty well sealed. i'm somewhat ashamed to admit that I bug bombed it, though obviously not when any substrate was in there. I also have borax on the threshold, and sticky traps, and a bug zapper. I'm gonna spread diatomecous earth around the outside today. I hear humidity renders it ineffective. Crawly bugs, specifically earwhigs are a fucking nightmare here.

doubtful that it attracts bugs. Though a bunch of flies and moths commited suicide into the tank that I left sitting unused for about a week. It was starting to anaerobically ferment, and smells like horse shit. I soak in burlap sacks and let them sit on cinder blocks to drain. I use them when they are drained and any excess water comes out after i poke holes. moisture in straw can be up to 70% unlike sawdust.

Try onion/vegetable sacks. They are poly prop, I get at least 10 runs out of one and they are cheap as.

the sawdust i have measured hydrated fully at around 70% moisture as well.
Solarity, where do you get those onion bags?

I get mine in small quantities from eBay (uk) I assume you have the same in USA, though may be called something different! This is what I mean:

For hydrating grain in bulk I just started using woven sandbags.

I was looking at some of those the other day. If they have limited uses though it may not be worth it for the ones I was seeing but I"m keeping my eyes out.

Hydrated Lime Soak Pasteurization is getting TWO THUMBS UP from me.
I have been playing around with Pleurotus Ostreatus in bread bags, boxes and buckets. Pasteurization has been accomplished by hot water bath. My problem has been 100% colonization of the bulk substrate (bagasse).
The last two buckets I did (hot water pasteurization): Bucket 1 did not fully colonize and never fruited. Bucket 2 colonized where the rye spawn layers were (but not 100%) and fruited.
Here is a pic of the top of Bucket 2:
 The spawn did not fully colonize the substrate .. and as you can see, there is fruiting. (out of aprox. 1/3 of the holes that are over the spawn layers).
This time I did two buckets pasteurizing with lime water. Colonization of the bulk substrate was rapid and robust:
  and the two buckets are now fruiting (from probably 4/5ths of the holes.
Exciting. I'm very enthused with the hydrated lime pasteurization.
edit. here are pics of Bucket 1 (Bucket 2 is a day behind). It is fruiting out of damn near all the holes!

Awesome uncle rico! That's very cool to see the two pasteurisation styles side by side. It's definitely a technique that needs to be explored more...I can't see the downside!

My first run is two buckets with a lime soak but I also soaked it in soap water first and then did a sub par pasteurization of it. It is colonizing quickly and its only been 2 days! I did a little over 4 pounds between the two of them and failed to reach the top by a few inches. I'm really not sure if I'm doing a high spawn rate but I plan to toy with it. Straw is definitely fast. I have more straw soaking right now in just plain lime water. I will spawn it tomorrow to at least 2 more buckets maybe 3 if I'm lucky. Hope to post pics soon.

Looks like the downside is looking for a place to throw the water after you're done... I have a blackberry patch in the greenbelt behind my place, was thinking about giving them the water, but I'm not sure what I'd do after they're all dead.
I'm guessing there's gotta be a way to neutralize it, maybe with acetic acid or something.

You don't need to throw away the lime water, you can reuse it, especially if you do the lime shower. If you do want to dispose of it, use ascorbic acid to neutralize it down to a 7 PH.

You don't need to throw away the lime water, you can reuse it, especially if you do the lime shower. If you do want to dispose of it, use ascorbic acid to neutralize it down to a 7 PH.
How to store between uses? I would think that reusing it would lead to alkaline tolerant bacterias as they sit in the solution between uses. Or am I just paranoid?
I will definitely look into lowering the pH, but will probably use phosphoric acid since it's much cheaper and readily available.
