Reworks Gleba's progression and place in the game significantly.

It eases the difficulty of the pentapods by making the Gleba spawn point always on a largish island, so you can make a limited factory without worrying about the pentapods. It also makes the yumako mash and jelly to bacteria recipes actually usable, allowing a simple, though inefficient, method of producing iron and copper on the planet, and boosts all plants' seed yield by 25% so that you don't run out if you're not using biochambers.

It also makes Gleba much more rewarding. It buffs the biochamber via adding more recipes, for example plastic from oil and holmium solution, and adding a preserved form of nutrients that last more than long enough to allow them to be reasonably used in places that aren't Gleba. Additionally, you can now research two levels of research productivity technology using agricultural science (as opposed to it being entirely a post-game research). The goal was to make Gleba more on par with the other planets in rewards.

However, the planet's also more difficult. There are the additional farmable crops, the boompuff (used for sulfur, rocket fuel, and a new recipe to craft bacteria directly into ore, but tends to explode), the teflilly (used for plastic and carbon fiber), and water cane (makes wood). The agricultural science pack now is a little more complex, and encourages engaging with the planet's mechanics.

Also, a new spoilage to landfill recipe has been added, to make it impossible to get softlocked with the new island spawn (unless you lose all your plants and seeds somehow).
