- Sandustry planter box requires 2,000 gold to unlock through the Refining section.
- Wet spores placed inside a planter begin growing into plants and can produce seeds.
- Plant destruction produces amethyst petals and gold that fall through the planter.
- Filters and conveyors keep spores, petals, water, and gold moving through separate routes.
- A controlled layout prevents plant growth from spreading beyond the intended farming area.
Sandustry planter box Setup Basics
The Sandustry planter box is a processing and farming component used to grow wet spores into plants. Once the plants mature, destroying them can produce amethyst petals and gold. The planter itself does not require a complicated interface, but the surrounding conveyors, filters, storage blocks, and fire source determine whether the system remains manageable.
The first major requirement is 2,000 gold. After reaching that amount, open the Refining section under the building options and unlock the planter boxes. Prepare the area before placing them so the output has somewhere to go.

| Requirement | Purpose | Recommended preparation |
|---|---|---|
| 2,000 gold | Unlocks planter boxes in Refining | Process and filter gold before attempting the setup |
| Wet spores | Starts plant growth | Keep a dedicated spore supply nearby |
| Planter box | Holds and grows the plant | Place it above a separated output route |
| Conveyors | Move resources between stages | Leave room for turns and vertical lifts |
| Filters | Separate resource types | Configure filters before opening the system |
The basic growth test is simple. Place a wet spore into the planter, then allow time for it to develop. The plant may produce a seed as it grows, and that seed can create another plant. Because plants can expand in multiple directions, a small test area can become crowded quickly.
Build the output route before adding several wet spores. Early preparation makes it easier to collect gold and petals without interrupting plant growth.
Growth Input
Wet spores begin the planter cycle and should be stored where conveyors can replenish the growing area.
Plant Output
Mature plants can provide amethyst petals and gold when destroyed with a suitable weapon or fire source.
Control Layer
Filters, walls, conveyors, and lifts keep growth and materials inside their intended routes.
Unlock and Place the Planter Boxes
Unlocking the planters is tied to the gold economy rather than a separate quest. Before spending the required gold, stabilize your sand-processing line. A clogged route can slow gold production, especially when wet spores or other materials mix with the output.
The most reliable preparation is to regulate the amount of sand entering the processing chain. A small spacing adjustment can reduce the amount of material arriving at once, which helps prevent piles from forming. Filters should also be checked while the line is running.
| Setup stage | Action | Success indicator |
|---|---|---|
| Gold target | Reach 2,000 gold | Refining unlock becomes available |
| Building menu | Open the Refining section | Planter boxes are visible |
| Test area | Place a small controlled structure | Inputs and outputs remain accessible |
| Input test | Add one wet spore | Growth begins inside the planter |
| Output test | Destroy the plant | Petals and gold fall through the planter |
Place the first planter in a compact testing area rather than immediately building a large farm. This makes it easier to identify which materials fall through, which items remain on the conveyor, and where water collects.
A planter-based layout benefits from vertical separation. Lifters can raise resources to a higher route, while filters can prevent unwanted materials from entering the next stage. The plants themselves remain in the growing chamber, while their drops travel through the lower collection path.
Do not fill a small test chamber with wet spores before confirming the output route. Seeds can create additional plants, and uncontrolled growth may block access to conveyors and filters.
Reach the Gold Requirement
Process sand and other available materials until the resource total reaches 2,000 gold. Regulate the incoming flow if piles begin forming in the processing line.
Open the Refining Menu
Enter the building options and locate the planter boxes under Refining. Unlock them only after the gold requirement is available.
Create a Test Chamber
Build a small enclosed area with enough room for a planter, a conveyor, and an output route. Leave access for later adjustments.
Add One Wet Spore
Place a wet spore into the planter and observe the growth cycle. Confirm that the plant remains in the intended chamber.
Verify the Drops
Destroy the mature plant and confirm that amethyst petals and gold fall through to separate collection routes.
Filters, Conveyors, and Output Routing
The planter system becomes more useful when each resource has a defined route. The key separation is between the growing input and the plant drops. Wet spores should be able to reach the planter, while petals and gold should fall through and move toward storage or later processing.
A filter configured to allow only the required material can keep the system organized. For example, a filter may be set to allow only cinder through a particular route, preventing petals and gold from continuing along the same path. This creates a controlled drop point for the materials that need to be collected separately.
| Material | Expected behavior | Routing priority |
|---|---|---|
| Wet spores | Enter the planter and support growth | Return or storage route |
| Plant seeds | May create additional growth | Keep inside the growing chamber |
| Amethyst petals | Fall through after plant destruction | Separate storage or later processing |
| Gold | Falls through with plant drops | Filter away from petals |
| Water | Can pass through gaps and collect below | Provide a drainage or return path |
Gold and petals should not be treated as identical outputs. The heavier gold drops first, while petals can settle above it. If the two materials share a collection route, a second filter or sorting stage may be needed.
Conveyors are useful for moving spores along the upper or side route, while lower conveyors can carry the drops away from the planter. Vertical lifts help create a boundary because plants cannot pass through the lift or filter structure. This keeps growth in the chamber while allowing resources to leave it.
A stable layout should let wet spores reach the planter, keep plants inside the growing area, and move gold and petals away without creating a mixed pile.
| Component | Best role in the layout | Common placement |
|---|---|---|
| Planter box | Plant growth chamber | Above the drop collection route |
| Conveyor | Horizontal material transport | Beside or below the planter |
| Filter | Resource separation | Before storage or a new processing line |
| Lifter | Vertical separation | At the edge of the plant chamber |
| Storage block | Temporary holding area | At the end of each output route |
When water appears in the structure, treat it as a routing issue rather than an empty gap. Water can move through open spaces and may eventually return to a lower section. Add a filter or drainage path where necessary so it does not interfere with the spore supply.
Plant Destruction and Automation Design
Plants can be destroyed with several tools, including a flamethrower, gun, or rocket launcher. The flamethrower is the clearest manual test because it allows you to burn plants while watching the petals and gold move through the layout. A gun can speed up individual destruction, while a rocket launcher can affect a larger area but may be less precise.
Manual burning is useful during testing, but it becomes repetitive once the planter area is producing continuously. The long-term objective is to design a chamber where plants grow in a restricted space and can be burned without requiring constant player attention.
The main design principle is separation. Place the planters so plants grow in the enclosed upper area. Leave the lower path open for petals and gold. Use a filter to stop unwanted materials from traveling into the wrong section, then move the outputs toward storage.
Automation depends on keeping the plants in a burnable chamber while allowing their drops to fall into a separate collection route. Test the manual cycle before expanding the design.
Flamethrower
Best for controlled testing and burning plants in a confined area. Watch for fire being smothered by dense growth.
Gun
Useful for targeting individual plants or clearing a small section when precision matters.
Rocket Launcher
Can clear a wider area, but use it carefully near conveyors and resource routes.
A practical testing sequence is:
- Allow several plants to grow inside the chamber.
- Confirm that seeds do not escape into the conveyor network.
- Burn a small section and observe the drop order.
- Follow the gold and petals through the filters.
- Check whether water or wet spores are blocking the collection route.
If the growth chamber becomes overfilled, enlarge the room before adding more input. Dense plants can restrict movement and reduce visibility, making it difficult to identify a blocked filter or misplaced conveyor.
| Test | What to observe | Adjustment if it fails |
|---|---|---|
| Growth test | Plants remain in the chamber | Add walls, filters, or lifts |
| Drop test | Petals and gold fall through | Reposition the planter or lower conveyor |
| Sorting test | Gold separates from petals | Add a dedicated filter route |
| Fire test | Plants can be destroyed safely | Increase access or reduce plant density |
| Flow test | Water does not block outputs | Add a return or drainage route |
Planter Box Checklist and Farming Priorities
The planter system is easiest to manage when built in stages. Start with one planter and one input route, then expand only after the material flow is predictable. This approach reduces the chance of creating a large plant mass that blocks the collection system.
Use the checklist below before treating the layout as ready for regular production.
Planter Setup Checklist:
- Reach 2,000 gold and unlock planter boxes under Refining
- Build a controlled chamber with room for plant growth
- Place one wet spore and confirm that growth begins
- Separate amethyst petals and gold with filters or conveyors
- Test manual plant destruction before expanding the layout
| Priority | Objective | Why it matters |
|---|---|---|
| 1 | Unlock the planter | The system cannot be tested before the building is available |
| 2 | Control wet spores | A stable input prevents sudden overgrowth |
| 3 | Protect the output route | Gold and petals need room to fall and move |
| 4 | Separate materials | Mixed drops can create an additional sorting problem |
| 5 | Expand gradually | Small tests reveal blockages before they spread |
For a dependable farm, keep the spore supply close to the planter but outside the plant chamber. This allows conveyors to replenish the planter without placing the storage area inside the growth zone. Likewise, keep gold storage away from petal storage if the two materials will be processed differently later.
The most important maintenance task is checking for clumps. If sand, spores, water, or plant drops begin piling up, pause expansion and inspect the nearest filter. Regulated flow is generally more useful than simply adding more conveyors.
Expand the farm only after one planter completes a full cycle cleanly. A compact layout with reliable sorting is easier to scale than a large layout with hidden blockages.
Sandustry Planter Box FAQ
Q: How do you unlock the Sandustry planter box?
Reach 2,000 gold, then open the Refining section in the building menu. The planter boxes are available there after the requirement is met.
Q: What do wet spores do in a planter box?
A wet spore starts plant growth when placed in the planter. Growing plants can also produce seeds, so the surrounding chamber should be controlled.
Q: What do plants drop when destroyed?
The setup described here produces amethyst petals and gold. Both materials fall through the planter and should be routed through separate collection or filtering stages.
Q: Which tool should you use to destroy planter plants?
The flamethrower is useful for controlled testing. A gun can target smaller areas, while a rocket launcher affects a wider area and requires more caution around the layout.
If the planter route stops moving, inspect the filters, water path, and mixed gold-and-petal output before adding more spores or planters.
The planter system rewards careful routing rather than immediate expansion. Unlock the building, test one wet spore, confirm the drop behavior, and then build the filtering and conveyor network around that proven cycle. With the plants contained and the outputs separated, the setup can support a more consistent supply of amethyst petals and gold in Sandustry.
