Grow Canola and Distill Plant Oil
Plant Oil is useful in polymer synthesis, and Canola offers an aboard-growing supply that can be processed in a Distiller.
Canola Multidoigt seeds at Greenhouse Tower; grow the crop aboard the airship.
Repeat while you have seeds and plot inputs. Seed return is only a small chance, so replenish seeds at Greenhouse Towers rather than assuming each harvest sustains the loop.
Stop distilling when your planned Plant Oil recipe stock is met, or pause planting until you have another seed and the plot inputs to grow it.
