Quick Answer

The current Planter Box chain starts with Seed, not Spore. A Seed that touches Water becomes Wet Seed. A Wet Seed that touches a Planter Box grows into a Flower. Destroying a Flower drops 1 Gold and 4 Amethelis.

For the full crop branch, see the Plants and Seeds hub. For the upstream Seed source, see the Kinetic Press guide.

Current Planter Chain

Step	Input	Process	Output
1	Burnt Residue	25+ block drop through Kinetic Press	Gold + Seed
2	Seed	Touch Water	Wet Seed
3	Wet Seed	Touch Planter Box	Flower
4	Flower	Destroy or burn	1 Gold + 4 Amethelis

Older guides may call Seeds "Spores" or Wet Seeds "Wet Spores." Use the current names when setting filters and reading the in-game material labels.

Layout Principles

Keep the Planter Box module separate from the Kinetic Press tower:

Let Seeds leave the press area before touching Water.
Wet Seeds should reach Planter Boxes in a thin, inspectable stream.
Keep Gold collection below the plant output path.
Route Amethelis away from Gold before it piles into the same filter.
Keep fire or harvesting tools outside the Seed wetting lane.

The easiest first module is a small contained planter lane with one Water contact point, one Planter Box surface, and a collection path below.

Best Wet Seed setup

Wet Seeds should be made close to the Planter Box, not in a giant shared water tank. The cleanest beginner pattern is:

Split dry Seed away from Gold immediately after the Kinetic Press.
Feed Seed into a short, shallow Water contact lane.
Let only newly made Wet Seed reach the Planter Box.
Keep the Water source beside the lane, not mixed into the main output chute.
Add a visible overflow so extra Seed does not pack the wetting point.

If Wet Seeds float, drift, or clog, reduce input first. A slow seed drip is easier to automate than a packed wet pile.

Flower farm without clogs

Planter automation usually fails because every useful output tries to occupy the same small space. Give each material a job:

Output	Route
Flower	Growth and harvest cell
Gold	Collector or Gold storage
Amethelis	Dryer / Florinol branch
Loose Seed or Wet Seed	Return, re-wet, or overflow
Vines or seedlings	Cleanup lane, burn zone, or isolated growth boundary

Keep fire and harvest tools away from the Water contact lane. If the farm burns its input, move harvesting below or beside the plant growth area instead of firing through the seed lane.

How to stop vines and seedlings

Vines and loose plant growth are a layout problem. Contain the farm before scaling it:

place solid boundaries around the growth cell;
keep a cleanup corridor where the player can reach new growth;
use Filters to keep Gold and Amethelis from blocking fresh Wet Seed;
avoid open vertical shafts below the farm unless they are intentional output routes;
test one Planter Box for several minutes before adding more boxes.

Filtering Strategy

Material	Where it belongs	Why it matters
Seed	Dry storage or Water contact lane	Seeds should not be wetted until the planter input is ready
Wet Seed	Planter Box feed	Wet Seeds are the growth input
Flower	Growing area	Destroy only when the output path is clear
Gold	Collector lane	Keep it out of plant input filters
Amethelis	Botanical output lane	Used later in Amethelis processing

If your planter stops, look first for an output blockage. Plant outputs are useful only if Gold and Amethelis can leave the module.

Common Mistakes

Problem	Cause	Fix
Nothing grows	Seed never touched Water, or Wet Seed never touched Planter Box	Add a clear Water contact point before the Planter Box
Wet Seeds wash away	Water lane is too deep or uncontrolled	Keep the wetting channel small and contained
Gold and Amethelis clog together	No output split	Add filters or separate fall paths below the Flower area
Fire spreads into the input	Harvest zone too close to Seed lane	Separate growth and harvest areas
Vines grow into the factory	Growth cell has no boundary	Wall the farm and add a cleanup corridor
Seedlings or petals jam the farm	Output has no dedicated route	Split botanical output before it reaches the planter input
