Regardless, all that bacteria would smell.  On the flip side, if you
bought a "roomfull" of bacteria, assuming optimal growing conditions,
in no time you'd have two rooms of bacteria, then a little later
you'd have three rooms.  They would keep growing until they ran out
of food :(  The ultimate upgrade
