× clear enough mud so that the multi-use plates at (23,22) and (27,22) are free, ensure that the mud can't grow on the two single-use plates, and get out of the room, all within a single growth cycle (because in the end the clone has to end up on the western arrow-plate).
I can't kill the mud mother, because I need it to grow it on the plates in the corners (with real Beethro presumably trimming mud growth then finishing the room).

But I can't seem to do this, I'm either closed in or can't clear enough mud.

×The first timeclone should wait diagonally adjacent to the (27,22) pressure plate so as to cut there immediately after the gel growth; then cut through the gel in a V shape to the other pressure plate.
