Best Sandustry Planter Box Designs Guide

What does a Planter Box do?

Official source notes describe the Planter Box as the building that turns Wet Seeds into Flowers. When a Wet Seed touches it, a flower grows. Gold and Amethelis are the only solid pixels listed as able to pass through the Planter Box.

Start with one contained module

Build a single planter section with a clear Wet Seed entry and an accessible collection area below. The supplied notes say filters and lifters can help contain plant growth because plants do not pass through them. This gives you a controlled place to see whether seed delivery, growth, harvesting, and collection all work.

Separate the outputs

Keep Gold, Amethelis, Seeds, spores, and water from accumulating in the same channel. Use filters and dedicated routes so a buildup in one output does not stop the planter itself. Do not scale the seed input until mature flowers can be cleared consistently.

Expand after observing a full cycle

A single flower proves the mechanic, not the factory layout. Watch a full grow, harvest, and output cycle before copying the module. Costs and exact harvesting options are patch-sensitive, so verify current unlock details in-game.
