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.

Sand: 10% fertility, no GrowSoil
Stony soil: 70% fertility, legal farm ground
Hydro basin: 2.8 fertility, 70W each
Pump truth: soft sand becomes sand, not soil
Available Strategy Pathways Three honest ways out of a sand-heavy map

Path 2 · Tech & Infrastructure

Replace the map with indoor farming

Hydroponics is the terrain-independent vanilla answer. Once the basin exists, the floor is no longer the bottleneck.

  • Hydroponics research costs 700 after Electricity in 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.
Best when the map has almost no legal farmland.

Path 3 · DLC Terraforming

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.
Best when you own Odyssey and want a slow conversion project.

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.

Terrain Reality Check What each tile actually means for farming
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.
Hydroponics basin 280% Uses basin logic Not applicable Terrain-independent food engine. Best honest answer when the map has no field.
Core Crop Table Numbers that matter on marginal legal ground
Crop Min Fertility Fertility Sensitivity Grow Days Yield Sow Tags
Rice 70% 1.0 inherited 3.0 6 raw rice Ground, Hydroponic
Potatoes 70% 0.4 5.8 11 potatoes Ground, Hydroponic
Haygrass 70% 0.6 7.0 18 hay Ground only
Corn 70% 1.0 11.3 22 corn Ground only
Research & Build Costs Hydroponics vs moisture pump in local defs
Hydroponics 700 research Research after Electricity.
Hydro basin 100 steel + 1 component Each basin draws 70W and uses fertility 2.8.
Moisture pump 1200 research After MicroelectronicsBasics with hidden Machining.
Pump build 75 steel + 4 components 150W, 6.9 radius, 60 days to full spread.
Local runtime note: in 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.
Desert Opening Planner Turn ugly map conditions into a first-10-day plan
Opening Field 12 tiles Keep it small enough that sowing finishes today.
First Crop Rice Use speed when the colony is close to empty cupboards.
Plan Type Token pocket This map wants a bridge system, not a fantasy farm.
Second System Hydro later Decide the follow-up before the first harvest lands.
With only a token patch of legal ground and four days of food, the colony should treat farming as a bridge, not as the whole answer.
  • 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.
FAQ The questions players actually ask on sand maps
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.

Fast Answer

In local RimWorld 1.6.4633 rev1266 Core data, you still do not solve plain sand by drawing a normal grow zone on it. Solve it by routing around the dune: use stony soil or soil pockets, switch to hydroponics if the map offers no field, and treat the Odyssey lane as its own DLC project.
