How to Automate Flowers in Sandustry: Full Guide

Direct Answer

Wet your Seeds with Water, separate Wet Seeds from dry ones, deliver Wet Seeds to Planter Boxes, let them grow into Flowers, then destroy the mature Flowers with Fire or another method to collect 4 Amethelis and 1 Gold per Flower head. A Pyro Dispenser heated by a Thermal Buffer can automate the harvesting step. Vine does not yield the same output as Flower heads.

Dry Seeds that did not convert should loop back to the Water stage. Vine does not produce the same output as Flower heads — target the Flower heads specifically.

Step-by-step setup

1
Wet your Seeds
Bring Seeds into direct contact with Water. Seed + Water → Wet Seed. Seeds normally come from the Kinetic Press (one Gold + one Seed per Burnt Residue drop).
2
Separate Wet from dry
Wet Seeds share the same density as Water and float; dry Seeds are denser and sink. Use this difference to route Wet Seeds forward and return dry Seeds to the Water stage. Filters, Conveyors, Launchers, or Clearing Frames can help.
3
Deliver to Planter Boxes
A Wet Seed grows when it contacts a Planter Box. Keep the delivery path clear — growing plants can absorb additional Wet Seeds and expand. Use buildings to enclose the growing area.
4
Harvest with Fire
Destroy mature Flowers with Fire, tools, weapons, or explosives. Each Flower head releases 4 Amethelis + 1 Gold. For automation, a Pyro Dispenser heated by an adjacent Thermal Buffer produces recurring flame bursts. Lava is not a mandatory fuel.
5
Collect the output
Gold and Amethelis fall through the Planter Box. Leave clear collection space underneath, and route the two outputs onward before scaling production. Use an Aerokinetic Fan for large Amethelis piles.

Component checklist

Component	Role	Required?
Seed supply	Planting input — usually from Kinetic Press	Yes
Water	Turns Seed into Wet Seed on contact	Yes
Wet / dry separator	Routes Wet Seeds forward; returns dry Seeds to Water	Yes
Planter Box	Grows Wet Seed into Flower (Tier 3, 2,000 Gold)	Yes
Harvest method	Fire, tools, weapons, or explosives destroy mature Flowers	Yes
Collection route	Gold and Amethelis fall through the Planter Box	Yes
Pyro Dispenser	Recurring flame bursts for automated harvest (Tier 3, 2,000 Gold)	Optional
Thermal Buffer	Supplies heat to Pyro Dispenser — Lava is not mandatory	Optional
Aerokinetic Fan	Moves large Amethelis piles (density 40, Wisp type)	Optional

Layout rules

✓ Do

Separate four zones: Seed wetting → Wet Seed routing → plant growth → harvest + collection.

✓ Do

Enclose growth area with buildings to prevent uncontrolled plant spread.

✗ Don't

Scale Planters early. Get the full loop working reliably before adding more.

✗ Don't

Mix logistics with growth. Keep the Wet Seed delivery lane separate from the growing chamber.

Troubleshooting

Seeds arrive but nothing grows

Cause: Seeds are still dry — only Wet Seeds plant on a Planter Box.
Fix: Verify Seeds contact Water. Dry Seeds are denser than Water; Wet Seeds are not.

Wet Seeds stay suspended in Water

Cause: Wet Seeds share the same density as Water — they float instead of sinking.
Fix: Design the wetting section for this behavior. Use Filters or gravity-based separation.

Dry Seeds reach the Planter Boxes

Cause: The separator is not catching them after the wetting stage.
Fix: Route dry Seeds back through the Water loop until they become Wet Seeds.

Farm spreads out of control

Cause: Growing plants absorb extra Wet Seeds and expand in all directions.
Fix: Reduce the incoming Wet Seed pile. Enclose the growing area with buildings.

Mature Flowers remain in place

Cause: Planting works but the harvest step is missing or not firing.
Fix: Add Fire (Pyro Dispenser) or another repeatable destroy method.

Output backs up and stalls production

Cause: Gold and Amethelis collection path is blocked or too narrow.
Fix: Clear the collection route below the Planter Boxes before adding more Planters.
