Casing with old material
    #1639245 - 06/17/03 10:47 AM (14 years, 4 months ago)

I made a casing material up about 2 weeks ago... i sterilized it and it sits in an air tight container... the mix is 60/40. could i use this to case again? would i have to do anything to it again?

You could use it, but assuming that no contaminants have been able to enter the casing mix is always risky. If you want to be safe, sterilize it again. If you'r absolutely 100% confident that no contams could have found their way to the mix, you can save yourself some time. But personally, I'd go for another sterilization round.

well yeah i thought about that, but like that would mean i'd need to add some more water, and then nuke it again. it just seems as though that can't be too healthy for the casing material

If you need to add some water, do so. Sterilizing the material again won't degrade it. Keep in mind that the casing material is supposed to contain no life at all at the moment you put it over the colonized substrate, and nutrients are not primarily absorbed by the mycelium from the casing but from the (crumbled) cakes, so you don't have to worry about degradation of the nutrients in the casing. Besides, you sterilize the BRF cakes as well, and the nutrients aren't aversily effected by the process, otherwise the mycelium wouldn't be able to grow. But, as I said, there's no need to worry about the nutrients in the casing layer in the first place.

I don't see in which way you could damage the casing mixture by sterilizing it again. So be safe, and sterilize again!
