How long will pasteurized bulk substrate last if I don't inoculate it right away?

By pasteurizing many bacteria and some molds still survive in the substrate.



By pasteurizing many bacteria and some molds still survive in the substrate. If you leave the pasteurized substrate uninoculated, it will "spoil" eventually.
The basic principle of spawning bulk substrate is the same regardless of the type of mushroom
or substrate. COLONIZATION MUST PROCEED AS RAPIDLY AS POSSIBLE TO PREVENT OTHER
ORGANISMS FROM BECOMING ESTABLISHED. Once the mushroom mycelium becomes dominant,
natural antibiotics secreted into the substrate inhibit competitors.
So, it's best not to store pasteurized substrate more than a few days, if at all.
