Combine one Seed with one Water pixel to make a Wet Seed, then move it onto a Planter Box to grow a Flower.

A Sandustry Wet Seed is created when a Seed absorbs a Water pixel. The resulting slushy material can be launched and planted, but its Water-like density makes it harder to remove cleanly from a wetting tank.
How to make a Wet Seed
The current official Water page gives the reaction directly:
1 Seed + 1 Water → 1 Wet Seed
Bring dry Seed into contact with Water. The Water pixel is absorbed rather than duplicated, and the Seed changes into the current Early Access material named Wet Seed.
Older Demo pages may call the equivalent material Wet Spore. Do not use that name or its old processing chain for the current version.
Why Wet Seeds stay in the Water
The official Wet Seed page lists Wet Seed and Water at the same density. Wet Seeds can therefore remain suspended instead of sinking cleanly to the bottom of a tank.
Dry Seeds are denser than Wet Seeds, so the two seed states can separate naturally when mixed. This difference can help you observe which material has reacted, but the collected sources do not establish a single high-throughput separator layout.
Keep the wetting chamber small while testing. Watch whether Wet Seeds gather at the Water surface, remain suspended, or reach the chosen outlet before scaling the design.
Sending Wet Seeds to a Planter Box
Wet Seed is launchable and is processed by a Planter Box. When it touches the Planter Box, it grows into a Flower.
The Planter Box allows Gold and Amethelis solid pixels to pass through, so leaving collection space below it supports the output route described in the Planter Box guide.
The official pages do not document an exact maturation time, fixed output per Seed, or a complete automatic harvesting cycle. Those values should be checked in the current client rather than inferred from an older video.
Quick troubleshooting
- Dry Seeds collect at the bottom: they have not all contacted Water yet.
- Wet Seeds do not sink: expected; they share Water's listed density.
- The Planter Box does nothing: make sure the input is Wet Seed and physically touches the box.
- An old guide says Wet Spore: it was made for the Demo-era terminology.
- A large tank clogs: test a smaller chamber before assuming an unverified filter layout will scale.

FAQ
How do you make a Wet Seed in Sandustry?
The current official Water page gives the reaction as 1 Seed plus 1 Water becoming 1 Wet Seed. The Water pixel is absorbed rather than duplicated.
Why do Wet Seeds not sink in Water?
The official Wet Seed page lists Wet Seed and Water at the same density, so Wet Seeds can stay suspended instead of sinking cleanly to the bottom of a tank.
Is Wet Spore the same thing as Wet Seed?
Wet Spore is the Demo-era name for the equivalent material. Use Wet Seed and its current processing chain for the Early Access version.
What is Wet Seed used for?
Wet Seed is launchable and is processed by a Planter Box. When it touches the box it grows into a Flower.
