Oyster mushroom

Hello, has anyone used hydrated lime in pasteurizing mushrooms? I'm curious if it works, what quantity should be used, and does construction lime work?

I assume you mean pasteurizing straw substrate. A quick question: what kind of construction lime do you have?

There are four kinds of construction lime: quick lime, slaked lime, fat lime and hydraulic lime:

I cannot find any info about using any of these kinds of lime to pasteurize  straw substrate.

Therefore, I'd  probably stick with hydrated lime that's low in magnesium, as it's been proven to work. This video by Tony at Freshcap Mushrooms explains exactly how to do it:



Perhaps some else on here has experience with using construction lime. Here is more info about hydrated vs. hydraulic lime:

Good luck!
