Agriculture, Biochambers, Overgrowth Soil Guide

If you’ve just reached Gleba and your farming setup feels awkward, this is the point where agriculture stops being a side activity and becomes the backbone of your base. Biochambers, artificial soils, and overgrowth soils let you turn the local biome into a controlled production system instead of fighting it, and the trick is to unlock them in the right order, get a simple crop loop running, and then add the more exotic terrain upgrades only when your nutrient handling is already stable.

Unlock the agriculture tools in the right order

Start with Agriculture as soon as you have Planet discovery Gleba. That opens the farm chain, and from there you should prioritize Yumako and Jellynut next, because both crop unlocks depend on Agriculture and they are the foundation for everything that follows. Once those are online, move into Biochamber and Artificial soil. Hold off on Overgrowth soil until much later; it asks for Biter egg handling, Production science pack, and Utility science pack, along with Automation science pack×1, Logistic science pack×1, Chemical science pack×1, Production science pack×1, Utility science pack×1, Space science pack×1, Agricultural science pack×1.

The important part is sequencing. You want a working farm chain before you spend science on specialty terrain. If you research overgrowth soil too early, you still won’t have the nutrient surplus or crop throughput to support it, and the result is a fancy expansion plan that stalls on basic inputs.

Set up your first crop fields with the right soil

Use Agricultural tower as your farm tool: it plants seeds and harvests mature plants, so your first goal is to feed it fields it can actually use. Jellynut seed can be planted on jellynut soil, and Yumako seed can be planted on yumako soil, so don’t mix the two crops in the same first-pass layout. Keep the setup simple and readable; you want to be able to tell at a glance which crop is feeding which processing line.

The key to getting started is turning the correct wetland tiles into buildable farm space. Artificial jellynut soil must be placed over wetland-jellynut, and Artificial yumako soil must be placed over wetland-yumako. Both are made in Assembling machine 1 and each craft turns seeds, nutrients, and landfill into a batch of farmable soil. That makes them the practical bridge between the native terrain and a controllable plantation.

Here is the core reference you should keep handy while you scale up:

Use artificial soil to get your first fields working, then let Agricultural Towers do the planting and harvesting. Don’t overcomplicate the layout early on; a clean, compact farm with obvious input and output belts is much easier to keep alive than a sprawling mess of partially fed plots.

Keep the biochain fed with nutrients and crop processing

The Biochamber is your late-game biological crafting structure, and you should treat Nutrients as the resource that keeps it alive. It uses Nutrients as both fuel and ingredient, which means nutrient supply is not an optional support system; it is the heart of the whole chain.

Your best early biological loop is to convert crops into processing products, then turn some of that output back into Nutrients. Yumako processing turns Yumako into Yumako seed and Yumako mash, while Jellynut processing turns Jellynut into Jellynut seed and Jelly. From there, Nutrients from yumako mash is especially valuable because it turns a small amount of mash into a larger amount of Nutrients. That makes Yumako a strong stabilizer for your farm, while Jellynut is still useful for its own processing line and for keeping your biological chain flexible.

You should also keep Nutrients from spoilage available as a fallback. Spoilage is the universal buffer for Gleba logistics, and when waste starts building up, that recipe lets you convert it back into something useful. Use that safety valve whenever your organic production is generating more decay than your main nutrient source can absorb.

Solve spoilage before it chokes your farm

Do not treat Spoilage as trash you can sort out later. It is created automatically over time, and it can appear in machines, on belts, in chests, and even while being held by inserters. If you let it sit around, it will spread through your logistics and make every buffer harder to trust.

Your first rule should be to route spoilage into a dedicated processing line immediately. If you want long-term value, send it to Nutrients from spoilage. If you want a stable material sink, send it to Burnt spoilage to make Carbon. Either way, the point is the same: give spoilage a job before it contaminates your supply chain.

Also remember that Nutrients made from spoilage are already half-spoiled on creation. That means you should use them promptly, not stockpile them blindly. Build your nutrient buffer so it flows directly into the Biochamber and related biological production, and keep the loop short enough that waste never has time to become a logistics problem.

Use overgrowth soil when you want farming in the wild biome

Once your core farm is stable, you can start thinking about Overgrowth soil. This is the step that lets you push crops beyond the initial wetland restrictions, but it is expensive for a reason: it asks for finished artificial soil, seeds, Biter egg, Spoilage, and Water. That makes it an expansion tool, not a starter tool.

Overgrowth Jellynut Soil is soil for jellystem and is placeable anywhere in the red biome. Overgrowth Yumako Soil is soil for yumako-tree and is placeable anywhere in the green biome. That flexibility is excellent once you have the logistics to support it, because it lets you farm in the wild biome instead of only on the appropriate wetland tiles.

Use overgrowth soil when you are ready to scale production outward and you already have reliable nutrient handling, spoilage processing, and crop seed supply. If you try to rush it, you will end up spending rare inputs just to create more things that need feeding. If you wait until your base can already support the chain, overgrowth soil becomes a clean way to extend your agriculture into the broader Gleba landscape.
