Can I Plant On This Sand Tile?
Plain sand is still a hard stop for normal grow zones in the local Core defs. The fast answer is to plant on stony soil, soil, or rich soil, pivot to hydroponics when the map has no legal farm pockets, and keep the Odyssey lane separate as a long-game terraforming path.
GrowSoil
Use the legal pockets you actually have
Stony soil, soil, and rich soil are the real early-game answer. This is where potatoes, emergency rice, and a small hay strip belong.
- Stony soil is local
GravelwithGrowSoiland 70% fertility. - Keep the first field small enough to finish sowing and harvesting on time.
- Potatoes are the poor-soil safety crop. Rice is the panic-speed crop.
Replace the map with indoor farming
Hydroponics is the terrain-independent vanilla answer. Once the basin exists, the floor is no longer the bottleneck.
Hydroponicsresearch costs 700 afterElectricityin the local Core defs.- Each basin costs 100 steel, 1 component, and consumes 70W.
- Rice fits the basin route well because hydroponics removes the poor-soil penalty problem.
Use the Odyssey long-game lane, not a fake grow zone
Keep the sand-to-soil route separate. It is a DLC project that changes the terrain economy over time, not a day-one food shortcut.
- Use this only when the colony can survive the delay.
- Do not confuse it with vanilla grow-zone behavior on plain sand.
- It is a long-game colony identity choice, not an emergency patch.
The Moisture Pump Reality Check
Myth: moisture pumps turn ordinary sand into fertile soil.
Fact: the local research and building defs only say moisture pumps dry wet ground and convert SoftSand into Sand. They do not convert ordinary Sand into Soil.

These fit bars are comparative signals from the local fertilityMin and fertilitySensitivity fields. They are useful for choosing between legal tiles, not for pretending sand became farm ground.
| Terrain | Local Fertility | Grow Zone? | Moisture Pump Result | Best Use |
|---|---|---|---|---|
| Sand | 10% | No GrowSoil |
None | Skip for sowing. Use legal pockets, hydroponics, or a separate DLC lane. |
| Soft sand | 0% | No | Sand |
Pump only when you need stable ground or to clean up a building site. |
| Stony soil | 70% | Yes | None | Potatoes first. Haygrass or rice if the clock or animal feed demands it. |
| Soil | 100% | Yes | None | Standard farm lane. Use rice for speed or potatoes for steady output. |
| Rich soil | 140% | Yes | None | Best natural tile for fast rice starts and high-value follow-up crops. |
| Shallow water | 0% | No | Gravel |
Pump when land recovery matters. The farm comes after the terrain dries. |
| Marsh | 0% | No | Soil |
One of the few places where moisture pumps really do move you toward farmable ground. |

Plant.cs, cultivated plants count as field crops when they sit in a grow zone or on a building that supports plants, and hydroponic cultivation is exempt from Odyssey drought penalties.- Toggle the fertility overlay and mark every stony soil, soil, and rich-soil patch first.
- Plant only the field size your current growers can finish immediately.
- Put potatoes on bad legal ground and rice on tiny urgent pockets.
- Plan the second food system before the first harvest is in the freezer.
Why does wild cactus grow on sand if my grow zone fails there?
Because those are separate rules. The local wild arid plant defs let plants like saguaro cactus and pincushion cactus exist at 5% fertility, but that does not give plain sand the growable terrain affordance used by normal farm zones.
Are potatoes really better than rice on stony soil?
Usually yes for bad legal ground. In the local crop defs, potatoes have a much lower fertility sensitivity value than rice, which is why they are the classic poor-soil answer once the panic window passes.
When should I stop trying to salvage the outside map and rush hydroponics?
When legal farm tiles are basically absent or too scattered to support a stable food loop. Hydroponics is expensive, but it solves the correct problem: missing farmland.
Is a moisture pump still worth building on desert maps?
Yes when the real problem is soft sand, shallow water, or marsh. No when the real problem is ordinary sand and you are hoping the pump will reveal soil under it.
