Project Oasis

Can every plant know exactly when it needs water?

Concept image. A glasshouse where each bed reports its own moisture.

Give every plant a way to say when it is thirsty, from a windowsill pot to a commercial glasshouse.

Prototype

The problem

Most plants die of watering, not of neglect — too much, too little, at the wrong time. The information needed to get it right already exists in the soil and the forecast. Nobody joins it up, so people water on a schedule and hope.

What we built

Give every plant a way to say when it is thirsty, from a windowsill pot to a commercial glasshouse.

Where it is now

Prototype — sensor bench tests running against a forecast feed. No field trial yet.

Research question

Can every plant know exactly when it needs water?

Why this matters

Most plants die of watering, not of neglect — too much, too little, at the wrong time. The information needed to get it right already exists in the soil and the forecast. Nobody joins it up, so people water on a schedule and hope.

Current progress

Prototype — sensor bench tests running against a forecast feed. No field trial yet.

Workflow

Prototype

Building the smallest thing that tests the claim.

How it could work

Problem

A plant needs water at a moment nobody can see.

Current world

A timer, a hosepipe and a guess. Water is used whether it is needed or not.

Quinn Labs idea

Read the soil, read the sky, water the individual plant only when it is actually needed.

Potential future

Growing spaces that spend water per plant rather than per zone.

Note

Not a schedule

Every failed watering product is a timer with an app. The decision has to be about the plant, not the clock.

Test

Forecast skip

Measure water saved simply by cancelling irrigation before rain. Establish the baseline before building anything clever.

Open questions

  • How cheap is cheap enough?

    A sensor per plant only works if it costs less than the plant. What is the honest floor?

Future possibilities

Research directions only. None of these exist, and some never will.

Questions we're asking

  • Can every plant know exactly when it needs water?
  • Low-cost capacitive soil sensors that last a season on one cell
  • Per-plant watering rather than per-zone irrigation
  • Forecast-aware scheduling that skips the watering before rain

We prototype possibilities. Not every question has an answer. Every answer begins with a question.
