Cultivate flowers and harvest gold using hydrated spores, irrigation piping, and planter boxes in Sandustry.

Botanical Agriculture and the Planter Box

The Planter Box module serves as a specialized cultivation bed that transforms hydrated spores into mature blooming flora, providing a steady alternative to traditional sand shaking and processing spores obtained from the kinetic slag press.

Hydrating Spores into Germinating Culture

Dry Spore grains cannot sprout on their own without moisture. Channeling spores into contact with liquid Water triggers the Spore + Water reaction, transforming dry powder into germinating Wet Spore clusters ready for agricultural planting — securing a steady moisture feed via the industrial water generation guide ensures unbroken growth.

Planter Box Seeding and Growth Cycles

Over several growth stages, the spore germinates into a flowering stalk, drawing ambient moisture to produce lush blossoms rich in concentrated minerals.

Floral Harvesting and Downstream Sorting

Destroying or harvesting mature flower blossoms yields refined Gold and byproduct petals, laying the groundwork for high-tier botany used in the flux emanator and voidbloom guide. Routing the harvest across an Allow Filter channels heavy gold nuggets into trade collectors while sending floral petals into secondary storage buffers.

Preventing Overgrowth and Irrigation Freezes

A frequent error in flower farming is neglecting temperature around the irrigation lines. If water pipes freeze into solid ice blocks during cold snaps, planter boxes starve and growth halts entirely. Ensuring water flows continuously and harvesting mature stalks promptly prevents botanical jams and maintains steady gold output.

Step-by-Step Walkthrough

  1. Supply clean water to the germination chamber to convert dry spores into wet spores.
  2. Use conveyors or drop chutes to deposit wet spores directly onto planter box beds.
  3. Allow flowers to reach full maturity before triggering automated harvesting.
  4. Direct harvest yields across filter gates to separate gold nuggets from petals.
  5. Maintain continuous water irrigation to prevent planter box dormancy.
