I've decided that i'm going to power my newest base with biofuel from an MFR bioreactor. For maximum efficiency I'm going to give it 9 different types of items to process. Conveniently, MFR farms can divide their plots into a 3x3 grid, and can grow different things in each square. This raises 2 questions; first, what should I plant in the 9 plots to get the highest number of items for the bioreactor(s) to process? Second, i'd like to ensure that the planter and bioreactor have no more than 1 stack of each item in their inventories at a time, to make sure that there's room for the 9 different types. How can I accomplish this?
