How to Make Voidbloom in Sandustry — Recipe & Automation

Current Voidbloom Recipe

The current Early Access recipe is:

1 Void Petal + 1 Redsand → 2 Voidbloom

The 2 Voidbloom output matters when planning throughput. Older Demo-era recipes involving Amethelis should not be carried into the current Early Access production chain.

The Materials Must Combine Vertically

The current Official Wiki explicitly says Void Petal and Redsand must combine vertically.

Either:

• Void Petal lands on top of Redsand; or
• Redsand lands on top of Void Petal.

Simply placing the two materials next to each other does not force the reaction.

For automation, build the mixing point so one stream reliably falls onto the other instead of allowing both materials to accumulate side-by-side.

From Voidbloom to Fluxite

The next step is:

1 Voidbloom → 1 Fluxite

Voidbloom must be supplied to the top side of a Flux Emanator. The Fluxite bloom grows below the machine and continues expanding while there is space and more Voidbloom is supplied.

That means a useful layout needs:

• controlled vertical input above the machine;
• open output space below;
• a way to collect or excavate the growing Fluxite;
• enough room that nearby structures do not immediately constrain the bloom.

Research Cost Is Not Build Cost

The current Official Wiki Research page is marked WIP and presently lists the Flux Emanator research unlock at 2,000 Gold.

That number is an unlock cost, not proof of the material cost to construct each machine.

What Still Needs Current-Build Testing

The official sources support the recipe, vertical mixing rule, top-side machine input, and 1:1 Fluxite conversion.

These optimization claims still need build-specific testing before being presented as fixed facts:

• maximum continuous throughput;
• exact optimal mixer dimensions;
• exact output growth speed;
• a single “best” anti-clog layout.
