Independent grow intelligence

Is your grow actually moving in the right direction?

Verdant connects drift, recovery, plant history, and outcomes your controller sees only as readings.

Verdant Free

Connect the sensors you already have.

Verdant reads your Home Assistant sensors over your own network and turns them into grow history — time in range, drift, and recovery against the stage each plant is actually in. About five minutes, and one token.

  1. In Home Assistant

    Create a token

    Generate a long-lived access token from your Home Assistant profile. Verdant never asks for your password.

  2. In Verdant

    Enter your URL and token

    Point Verdant at your Home Assistant address on your own network, paste the token, and test the connection.

  3. In Verdant

    Map sensors to a grow space

    Choose which entity feeds temperature and humidity. Verdant derives VPD itself, so units can never skew it.

  4. Read the full setup guide

Verdant Pro with Edge

Did your controller actually improve the grow?

Verdant Pro uses evidence from Edge to score stability, explain drift and recovery, and show where conditions may be heading.

What is Verdant Edge?

Edge runs locally with your grow. It gathers sensor and controller data, detects drift, and produces forecasts. Verdant then adds the plant history, grower actions, and outcome.

What Pro adds

  • Seven-day controller outcome verification
  • Drift, recovery, recurrence, and intervention quality
  • Forecasts from Edge in Timeline

Screens show fictional Northstar Garden data in the real Verdant app.

Outcome verification

Seven-day environment scorecard

See whether the controller kept the grow stable, how much data supports the result, and what pulled the week down.

Pressure ahead

Forecast context in the Timeline

See a likely target crossing from Edge beside the events and interventions that give it context.

What shaped the score

Deeper weekly evidence

Trace the strongest penalties back to drift, recurrence, recovery, reading coverage, and intervention history.

Free means free

No account. No credit card. No trial clock.

Verdant Free is not a trial and not a teaser. Download it and start logging — there is no sign-up step, nothing to enter a card for, and no countdown that switches the app off later. Verdant Pro comes from owning Edge, which you buy here as hardware, so there is nothing to subscribe to inside the app and no account for your grow records to be locked behind.

No sign-up

Open the app and start. There is no account to create and no email required.

No credit card

The app never asks for payment details. Edge hardware is sold separately, on this site.

No expiry

It is not a trial. The free features stay free and keep working offline.

Nothing held hostage

Your plants, journal, and photos are on your device, not behind a login.

Private by default

Build grow memory without giving up the grow data.

Your grow record stays on your device. You do not need an account, and you choose which services to connect. Verdant keeps explaining the grow even when the network is unavailable.

Why Verdant exists

Controllers manage devices. Verdant understands the grow.

Verdant is the independent layer for the plant context, grow memory, drift, recovery, and outcomes a controller cannot explain on its own.

Drift intelligence

Know whether a change matters

Verdant filters sensor noise into meaningful movement, persistence, recovery, recurrence, and instability.

Plant memory

Give environmental data a grow history

Stage, cultivar, photos, journal entries, interventions, and outcomes explain why the same reading can mean something different today.

Outcome verification

Find out whether the intervention worked

Verdant goes beyond “device on” by comparing targets, drift, recovery, overshoot, and equipment activity.

Controller independent

Keep the setup you already trust

Home Assistant and other controllers keep running the equipment. Verdant works above them and explains the result.

Calm by design

One issue. One focus.

Verdant reduces interpretation work instead of turning every signal into another alert or dashboard card.

Coach

Ask about intelligence Verdant already built

Coach lets you explore the same environment, plant memory, drift, and outcome history through conversation.
