Sandustry Planter: Wet Seed Production Guide

Quick Answer

The machine behind the “sandustry planter” search is officially named Planter Box. Its dedicated wiki page says a Wet Seed touching the box grows into a Flower, while Gold and Amethelis are the only solid pixels that can pass through it. Build a separate Seed-wetting area, deliver Wet Seeds without mixing them with dry Seeds, and leave clear routes for the products documented in your current version. Growth time, exact yield, and ideal box count are Pending confirmation because the official page does not provide them.

Understand the Confirmed Interaction

The Planter Box is a production building whose direct input is Wet Seed and whose direct growth result is Flower. The current Research page adds that harvesting Flowers yields Gold and Amethelis, but it is marked work in progress. The dedicated page specifies permeability: liquids and gases are not blocked, while Gold and Amethelis are the only solid pixels allowed through. That unusual behavior should shape the collection chamber beneath the box.

Stage	Confirmed behavior	Design response
Wetting	Seed must become Wet Seed	Use a controlled Water contact zone
Planting	Wet Seed touching Planter Box becomes Flower	Deliver one clean material stream
Permeability	Liquid and gas can pass	Do not assume the box seals a reservoir
Solid pass-through	Gold and Amethelis can pass	Keep a collection route below
Timing and yield	Pending confirmation	Size buffers from observation, not guessed ratios

The official beginner guide describes the plant stage as one part of a longer Gold-production chain. That means the planter should not be isolated from upstream Seed creation or downstream collection planning. Even so, connect one interface at a time. A whole chain built before a single Wet Seed reaches the box is difficult to debug.

Wet Seeds in a Separate Zone

Water reacts with materials, so do not wet Seeds directly above sensitive Filters or a mixed storage pile. Send dry Seeds into a small bounded contact area, allow them to become Wet Seeds, and remove the wet output before more dry material arrives. The box itself does not block liquids, making it a poor wall for uncontrolled Water. Use terrain or blocks whose liquid behavior is confirmed in your current build.

Isolate dry Seeds from Gold and other byproducts.
Introduce Water in a contained, observable chamber.
Verify that the material label changes to Wet Seed.
Move Wet Seeds to the Planter Box without crossing a dry-material sorter.
Keep a drain or recovery path for Water that passes the planting area.

Avoid quoting a fixed Seed-to-Water ratio from unversioned footage. The official pages establish the transformation but do not publish a current production calculator for this module. Use a small batch to understand your layout’s physical behavior. If Water reaches the next Filter, stop and repair containment before scaling.

Collect Outputs Without Blocking Growth

Because Gold and Amethelis can pass through the Planter Box, the space below it is a natural collection interface. Keep that space open and route each material away before a deep mixed pile forms. A Filter can isolate one selected solid, but its dedicated page warns that density and pile height affect whether pixels reach it. Separate the most important dense output early and maintain an overflow.

Do not let the receiving channel fill back up to the box. A blocked output makes it hard to distinguish slow growth from failed collection, especially when official growth timing is not documented. Provide a visible buffer below the box and a separate downstream sorter. The layout can remain compact without hiding the point where each material leaves.

Diagnose a Planter That Appears Idle

First inspect the input label: dry Seed is not the documented direct input, while Wet Seed is. Then confirm physical contact with the Planter Box and remove unrelated pixels from the contact area. Check whether output space below the box is available, since Gold and Amethelis need somewhere to pass. Only after these checks should you suspect a version-specific bug.

Seed never changes: verify Water contact and current material labels.
Wet Seed rests beside the box: adjust the delivery path so it touches the building.
Flower appears but outputs do not clear: open the area below and inspect the collection route.
Water enters sorting: move wetting upstream and add containment.
Observed yield differs from a guide: trust the current build; exact yield is Pending confirmation here.

The Research page and dedicated page may be updated at different times during Early Access. If their wording conflicts, compare both with the live tooltip and record the game version. Do not install an unofficial mod or executable to force a recipe. Report repeatable discrepancies through official channels.

Integrate the Planter with the Longer Refining Chain

The official beginner guide places the Planter Box among the core structures that contribute to Gold production, while the current Research page connects Flowers with Gold and Amethelis. This means the planter module has at least two downstream interests rather than one disposable output. Keep its collection area separate from the earlier Shaker Gold route until both branches have been observed cleanly. You can merge confirmed Gold later, but early separation shows whether the plant stage is actually contributing.

Amethelis should also receive a named or physically distinct buffer because the beginner guide associates it with later energy production. That guide outlines a longer state-change path involving Steam, heat, condensation, and a Florinol Battery, but those systems are outside the direct Planter Box reaction. Do not place thermal processing inside the planting chamber merely because the material will eventually be used there. Exact Amethelis yield and the preferred buffer size are Pending confirmation.

Audit the module at three boundaries: Wet Seeds entering, Flowers appearing, and documented solid outputs leaving below. If the first boundary works but the second does not, inspect contact with the box; if the Flower stage is visible but collection stops, inspect the lower chamber. This boundary method uses only documented roles and avoids assigning an unsupported cycle rate. Record a game version whenever you turn those observations into a reusable factory blueprint.
