    coffee grounds are essentially just a binder used in agar mix to harden it

    Oh, yes. I forgot about the agar. Is this the same thing that’s used as a food for bacteria in a petri dish?

      yesnt. agar is not exactly the food (it is one part of the food). we usually add other nutrients as well. consider agar like a staple bread (povides structure).
