Did I get the correct lime for pasteurizing straw?

I must have tried every place in a 25 mile radius and this was the only thing I could find that looks like it fits the bill.
It says hydrated lime on the bag and has a Mg content of less than 2%. I don't see CaOH2 anywhere on the bag so I'm not 100% it's the correct type.

yes hydrated lime is what you want, this part of the forums is for cultivation of hallucinogenic mushrooms though. you might want to post over in the gourmet and medicinal section if you're growing edibles. for cubes I would pasteurize the straw with heat.

Thanks for the reply. I'm planning on doing cubes on pasteurized straw. I'll be using lime in addition to heat for pasteurization.

kind of pointless to do both. lime pasteurization takes a day and you don't want to heat pasteurize that long. so what would you do lime then heat or heat them lime? seems like a total waist of your time
just soak your straw in warm soapy water to get the wax layer off then heat to 140-160F for an hour, most people just boil water and add it to the soap soak until the temperature is 150-160F or so.

Maybe I should have worded my thread title a bit better. I'm doing heat pasteurization with the addition of lime. It's not pointless as it raises the pH to around 12 and makes it more difficult for stuff like trichoderma to get a foothold.
You add your lime to your pasteuriztion bath which is after you've soaked your straw in water with dish soap.

if you're going to do it the RR way it only takes a little bit of lime https://www.shroomery.org/forums/showflat.php/Number/12702122
you can use bleach though, you already have it and it's cheap as fuck. or sodium hydroxide crystals if you have them for DMT or drain cleaning or soap

completely off topic, but everyone should try extracting DMT at least once :p the experience is out of this world. and its really not any more difficult than growing mushies. less time consuming, less materials, just a little more chemistry involved is all. all materials readily available online as well.. just dont buy a ton of sodium hydroxide or the FBI might think youre making massive amounts of methamphetamine >:p
as for the lime. yes its correct, but that has already been answered lol.

Enough boiling water poured into a container to fully submerge the sub will keep the temp between 160-170F for 90 minutes....
Straw and manure have microorganisms in them that have a scientific name that I can't remember a.t.m. ... maintaining 160-170f 90 minutes won't kill them....bleach will.....

Actinomycetes i believe are what youre referring to? i actually did some reading on it recently as im planning to use straw/manure lol.
Actinomycetes i believe are the main micro-organisms within manure that break down the stuff we DONT want, while helping maintain the stuff mushrooms DO want. helping for nutrients to stay. this particular micro-organism also doesnt die unless its in very high heated conditions, so substrate should most definitely contain this organism throughout the process as long as you dont go way overboard with heat. oh and bleach would most definitely kill it.
i could be wrong about Actinomycetes being the culprit for the help in nutrients and allowing plants to grow better but i literally just read this last night and i think im correct. maybe someone smarter can help though :p

Get the pH to 10-11. A lot of shroom farms use lime and bleach together for cold pasteurization. 1/2cup lime and 1cup bleach for 10 gal.
Bleach kills in killing concentrations like 1cup bleach in 2 gal of water

If you use straw you should either pasteurize it or ferment it.
You have it backwards. Straw is commonly bleach pasteurized, especially in countries where gas or wood for heat are in short supply. However, hot water or steam treating will provide better yields. RR

Don't listen to those who say bleach will kill mycelium. It's an accepted method of pasteurization, and live mycelium can withstand up to ten percent bleach, which is much stronger than any of the teks call for. Lime is also an acceptable method, thus I combine lime and hot water for great results, as demonstrated in the video.
I disagree about sterilizing straw unless you're going to inoculate and colonize it under sterile conditions. If you're making straw logs that get holes punctured right after making them up, then you don't want to sterilize. We pasteurize to kill mold spores, not bacteria, many of which generally survive the pasteurization process. RR
At the end of the day though you really just need to do the heat pasteurization.
The guy who posted bleach kills everything is just talking out his ass

There is no such thing as a "shroom farm" that's like saying the guy pulling 2 lbs dry from two tubs is running a factory in a warehouse... the proper prep is heat pasteurization...
Use bleach to disinfect surfaces, not "sterilize" straw.... and Rr is saying bleach for use since it's residue is not harmful to mycelium. ...dunk a cake in a bleach,water solution and watch what happens to the mycelium... big difference between a residue and a concentrate.

No one said shit about dunking cakes in bleach water. There's probably 200 RR quotes saying not to dunk cakes in bleach right next to saying not to dunk in h2o2
No such thing as a shroom farm?

Like no farms this big that chemically pasteurized straw since doing it with heat is ridiculous on this scale.
What the fuck are you talking about guy? Bleach doesn't sterilize anything. It's a sanitizer. And diluted way down you can pasteurize straw with it like half of every huge oyster farm does
If you're growing cubes or even edibles at home there's absolutely no reason not to heat pasteurize. Yields are better. RRs straw method includes PH adjustment during the pasteurization process for bot pasteurization. This isn't cold pasteurization but its borrowing some of the idea from it.
You can use a lot of different bases like lime, bleach, or lye to adjust the pH for the heat pasteurized straw if you want to adjust at all, you don't have to.
If you do cold pasteurization with only chemicals and no heat its not really pasteurization at all. It's preparation. But that aside you can use lime, bleach, like and bleach, or hydroxide. And probably any combination of those. Lime has the best yields reported by lots of sources. But heat pasteurized straw has better yield than any cold process

Lol that's a oyster farm or other commercial sized mushroom farm.... I don't know who here on these forums is running one dedicated to cubes .... one monotubs lasts me and friends a good while....
So unless these people are turning to a Internet forum after already investing a half a million dollars in a commercial farm to pick our brains for knowledge on how to run their commercial buisness I'd have to say that this whole "bleach pasteurization" tek is just like the countless others members that try to stand out and be different 
And another thing... pasteurization cold/hot does not effect the yeild of the substrate....that is solely genetics of the culture used to spawn....

When heat pasteurized the chemical you use to get the PH above 10 doesn't really matter. Actually iirc in the lets do straw video he might say that
Who said there was cube farms. No one thinks that...
It's not bleach pasteurization. It's heat pasteurized and you used bleach to raise the pH rather than lime. Bleach pasteurization involves no heat at all and I would suggest that to no one

It's called p.h up and it can be used to p.h the pasteurization water between 6.5 and 7 (ideal for p.cubensis) straw/hpoo/coir are all already within this range. 11 is way to acidic for mycelium.

This is on heat+sodium hydroxide to raise pH above 10. Didn't have lime, not going to buy some.
