Part 1 The problemWhy teams need this

01 · THE PROBLEM

When a batch comes back below spec, the post-mortem means pulling climate logs, irrigation data and lab certificates from separate systems. It takes 60 to 90 minutes and often ends in a guess. By the time anyone knows, the next batch is already growing under the same conditions.

Part 2 How it worksWhat it does, step by step

02 · WHAT IT DOES

A pilot for an indoor cultivation facility. When a lab result comes in, it's joined to the full climate history of the room that batch grew in. The team gets a plain-English explanation of what likely drove the result, a recipe recommendation for next time, and a growing library of what works.

03 · HOW IT RUNS

Step by step, as built.

  1. Catch the new result

    A new lab result row starts the run.

  2. Pull the room's history

    Every environment log for that room across the growing cycle is loaded.

  3. Correlate

    Average VPD, temperature, humidity and CO₂ are compared against the expected range for the outcome.

  4. Explain and recommend

    A plain-English insight and a recipe recommendation go to the recipe library and to the cultivation team in Slack.

04 · TOOLS AND APPS

05 · WHEN SOMETHING BREAKS

Failure is designed in.

Standard on every build

  • Schema validation before downstream writes
  • Retry and error routes for external API failures
  • Duplicate-safe processing and idempotent updates
  • Human approval where the action carries business risk
  • Execution logging for support and audit review

Part 3 The impactWhat it's worth, and how we'd build yours

06 · PROJECTED IMPACT

What it should change in the business.

Projections for a typical deployment. The calculation below shows the math, and you can put in your own numbers.

07 · ROI CALCULATION

How it pays back in your business.

The starting numbers are a hypothetical deployment sized to the projections above. Change any of them to your own volumes and costs, and the math updates underneath.

The math: 60 lab results analysed × 75 min × 12 months × 90% ÷ 60 = 810 hours a year × $40/hour = $32,400. Net value = gross value − $120 running cost a year.

08 · HOW WE'D BUILD YOURS

How we'd build yours.

  1. Discover: map the current process, systems, volumes, owners and exceptions.
  2. Design: define the canonical data model, approvals, retries and system boundaries.
  3. Build: implement credentials, nodes, validation and observable error routes.
  4. Prove: run controlled data through success, duplicate and failure scenarios.
  5. Operate: publish runbooks, ownership and measurable service levels.

SAME SYSTEM

Built for clients, inside their stack.

Workflows we built for a home-services contractor, a dental practice, a reserve-study firm and an indoor cultivation facility. Names are kept private; the workflows are real.
