I'm using the "Any planet start" mod for Factorio to force myself to really understand Gleba.
These blueprints produce half a belt of iron and copper, with a little power plant as well.
These use minimal technology (you'll need to research assembler 2's), but still have some nice circuit tricks, bootstrapping by dropping about 200 spoilage in each wooden box, plus some fuel in the power plant (with automatic restart if fruits get interrupted).
No unprocessed Yumako and Jelly Nut are used directly, ensuring the seed ratio stays positive. However, you'll need to implement some sort of control on your Agricultural towers to ensure you don't overproduce and allow fruit to rot.
