One contam cake will contam all cakes...seperate em. If the mycelium is slightly yellowish, and you see water on condensing on the side of the jar, then it's probably just a water stain, as far as the other colors, you can try to fruit em straight from the cake, but I heard that using unsterilized cow shit can save most contaminated cakes. The person used equal amounts of shit with crumbled cakes, mixed, and put an inch thick layer in a container. The shit was a little moist. He covered for a week, then sprayed, then when pinning he put in terrarium and sprayed walls so as not to spray the shrooms directly. I feel horrible that I don't remember his name so that I can give him full credit, but lotsa people saw it, and it was really great. It wasn't even that long ago, you should flip back a couple pages, I think it was called Cambodian Pics. I memorized the tek for future reference. But I'm getting carried away now, so anyway, experiment and learn.------------------
