Simple, compact bioflux production. Meant to serve as a stable source of nutrients for your actual factory.
Startup: put a handful of nutrients in the two leftmost chambers. Make sure the yumako keeps coming in, and put something in place to drain the seeds.
Don't worry if the jellynut runs out, this setup is self-sustaining and self-cleaning as long as there is yumako coming in.
The bioflux producers don't run with 100% duty cycle.
