One time I got a huge contam infection in my straw.
Thas was when I heated it too much for about 15-30 minutes. Almost to boiling point. (90C ~~ 200F)

The spawn never got a decent chance and all kind of molds (but mainly green mold) started for take of.

In some teks it is strongly adviced not to exceed 185F. I now know why.

Since straw is not so costy I would advice to start over. And watch that temperature! :laugh:

Are you making straw soup? :lol:Its hard to pasteurize straw like that.You should wait until it cools enough to handle then squeeze it out and load it in a pan with a lid(or foil)and stick it in the oven.Do you have any compost or castings to mix with the straw?Compost adds the micros that protect the substrate,thats why pasteurizing temps are lower.The heat does'nt kill everything in the substrate,thats why its called a 'host substrate'.Is your kitchen covered with straw?
