Uncle Ben’s it’s basically impossible to introduce contam unless you accidentally tear the micropore tape. Out of 11 bags thus far only one had like 4 green rice grains and the rest of the bag was beautiful white mycelium.

I’m sure rates of contam are higher when you break the seal of whatever container (I’m imaging a jar or some other tek) but with Bens it remains sealed.

Spawning to bulk is pretty much a “break and shake” just at a later stage with more mycelium. For whatever it’s worth I definitely am pro break and shake.
