That's a bad ass APE plate!


How big of a wedge does everyone use when going to grain? I've got some colonies a little bigger than a quarter I want to get onto grain. Just to clarify, I would be doing one colony per quart jar. Does that seem like enough?

Anyone have any ideas as to what hidden little contam is causing this CHAOS!
There are hints of light blue that are hard to pick up for my camera in all of them

Anyone ever try activated charcoal with agar mix just the same way one would use food coloring?

I saw a video where someone was growing some white bacteria on a petri dish, and used activated charcoal to make the agar black. Looked very cool, and would probably make it very easy to see what's going on.

Wouldn't harm mycelium growth or increase contam growth, would it?
