Greenhouse OS

The system that runs our greenhouse.

We started as a farm, and Greenhouse OS is what we built to run it: our own controllers, sealed 3D-printed enclosures and a console that knows every table.

A model of our greenhouse: germination trays, intermediate and final tables of lettuce, the controller by the door and crates of harvested heads outside. 01 Seed 02 Grow 03 Sale

A real farm, since 2018.

Greenhouse OS didn't start in an office. We built it here in Asunción, for the greenhouse we run every day.

Every head takes the same road.

Greenhouse OS follows it from the tray to the order.

  1. A germination table, its channels full of seedlings.

    01

    Seed

    Seeds start on the germination tables. Our controllers water them at 8:00 and 15:00, and each batch is logged for traceability.

  2. A final table of lettuce, the controller on its post and the nutrient tank.

    02

    Grow

    Plants move to the intermediate tables, then to the final ones. Misting follows temperature, humidity and dew point, and every table's EC is logged daily.

  3. Wooden crates of harvested lettuce.

    Sale

    At harvest, each table goes into stock and stock goes out as orders, all in the same console.

One reading moves the whole farm.

Every module reads the same world. When a table's daily EC goes out of range, the change carries down the whole chain on its own.

  5. OrdersOrders see what is really there

TaskAnd if the table gets stressed, the console suggests what to check.

Three parts, all built here.

The console
A 3D twin of the site, table by table, with the sun and moon computed for Asunción. Around it: traceability, conductivity, spraying, inventory, orders and tasks.
The controllers
Our own ESP32 boards that join Home Assistant over Matter. They water, mist, and update only over the local network.
The enclosures
Sealed, designed and 3D-printed here, for humidity held above 85%, condensation and nutrient aerosols.
