Fluxite Production in Sandustry
Fluxite becomes renewable once you unlock the Flux Emanator. First combine Void Petals and Redsand into Voidbloom, then feed the Voidbloom into the top of the Emanator and leave room for Fluxite to grow below it.

Fluxite production chain
Void Petal and Redsand meet vertically to make Voidbloom. Feed that Voidbloom into the top of a Flux Emanator and leave open space below for Fluxite to grow.
How to make Voidbloom
Void Petal and Redsand must meet with vertical contact. Side-by-side adjacency does not guarantee Voidbloom.
Bad
Void Petal │ Redsand
Side by side
✕ No guaranteed combination
The two materials need vertical contact. If your mixer fills but never creates Voidbloom, check the orientation before rebuilding the whole line.
How the Flux Emanator works
Voidbloom must enter from the top. Each Voidbloom becomes one Fluxite, which starts growing below the machine and expands outward while space remains.

Fluxite grows outward while space remains available. Keep the chamber away from exposed Lava; Lava destroys Fluxite terrain.
Flux Emanator needs
- Top — ✓ Voidbloom input
- Open Fluxite chamber — ✓ Open growth space
Space is part of the machine
Feeding Voidbloom is not enough. Fluxite grows outward, so the chamber under the Emanator has to stay open.

Simple Fluxite setup
If you only need steady Fluxite, start with a simple continuous feed and keep the growth chamber away from exposed Lava. Add logic only when you specifically need controlled batch filling, dumping or automatic reset behavior.

How to automate Fluxite production
Choose the simplest pattern that matches the job. Continuous feed is enough for steady Fluxite. Add a controlled cycle only when you need full → dump → empty → refill.
How should a Fluxite automation reset?
A working automation needs both a “start dump” condition and a separate “cycle finished” condition.
If your line dumps once but never refills, your system knows when to start the dump but does not know when that dump has finished. Add an empty/end-of-cycle condition that returns the gates to the Fill state.

There are several valid reset designs. The important part is the state transition, not one exact circuit.

Where does your cycle stop?
It dumps once, then won't refill
Both sides ready → Mix / dump → Chamber empty
Likely cause
Your cycle has a dump trigger, but no completed-cycle reset.

The Fluxite line eventually stops
- Upstream — Void Petal unavailable
- Mixing — Redsand / Petal no longer meet correctly
- Input — Voidbloom route blocked
- Output — Fluxite chamber full
- Logic — cycle stuck between states
Void Petal → Redsand → Voidbloom → Top → Open growth space

Target Fluxite is not always the actual mix output. Voidbloom is made in batches of two.
What is Fluxite used for?
Fluxite purchases upgrades for tools, weapons and drones.
Tools
- Grabber
- Shovel
Drill
Weapons
- Gun
- Flamethrower
- Rocket Launcher
Drones
- Hauler Drone
- Recon Drone
Not sure what to upgrade first?
A larger Grabber is a strong early quality-of-life upgrade because it makes moving larger amounts of material manually much easier.

How do you make Fluxite in Sandustry?+−
Combine Void Petals and Redsand into Voidbloom, then feed Voidbloom into the top of a Flux Emanator.
What is the Voidbloom recipe?+−
One Void Petal plus one Redsand produces two Voidbloom when they meet vertically.
Why won't my Fluxite automation reset?+−
A system that dumps once but never refills usually has a start condition but no end-of-cycle condition that restores the Fill state.
Why isn't my Flux Emanator producing Fluxite?+−
Check that Voidbloom is entering from the top and that there is open space for Fluxite to grow beneath and around the Emanator.
