An audit of your growing data.
Understand what your measurements say before you change the controls. We review the data from your greenhouse or indoor operation and turn the findings into practical next steps.
Scope, price and delivery date agreed before work begins.
Start with the question your operation needs answered.
Sensors tell different stories
Compare measurements over the same available periods and identify what needs a check on site.
Climate alerts need context
Review how long conditions last, when they change and which gaps affect the interpretation.
An upgrade needs a starting point
Establish what your existing data can support before planning new sensors, software or controls.
Your existing measurements are the starting point.
Start by describing what you record and the question you want to answer. We will agree a suitable period and the data needed for the review.
The enquiry form takes a description, not your raw files. We agree how to transfer the data after confirming the scope.
- 01Measurement export
- A CSV, spreadsheet or export from your controller: timestamp, time zone, sensor ID, measured values and units. For VPD, temperature and relative humidity must be available together.
- 02Operating context
- Crop and growing stage, room or zone, sensor positions, lighting schedule and relevant control settings, if available.
- 03Known changes
- Calibration, maintenance, equipment changes or periods when the logging was interrupted. Missing information can be recorded as a limitation.
From the first question to an actionable review.
- 01
Agree the scope
We clarify the question, available data, deliverables, price and timing.
- 02
Review the measurements
We check completeness and comparability, then analyse the agreed climate variables and review rules.
- 03
Walk through the findings
You receive a report with charts, the calculation approach and prioritised recommendations, followed by a discussion of next steps.

Our published VPD analysis compares two measurement streams, their coverage and the effect on review flags. It includes the method, charts, data and reproducible calculations.

Want an initial look at your measurements?
Our free sensor analyser checks a CSV in your browser. You can review the results and choose to attach its summary to an enquiry. The raw CSV stays in your browser.
Tell us what you want to understand.
Describe your operation, the available measurements and the issue you are investigating. We will use this to propose the scope of your audit.

How much does an audit cost and how long does it take?
The scope depends on the volume and condition of the data, the number of sensors and the questions to resolve. We agree the price, deliverables and delivery date before starting.
What if I do not have an export yet?
Describe your controller, sensors and the data you can currently access. We can first assess what can be exported and what is missing for a meaningful review.
Can the audit determine which sensor is correct?
A data comparison can reveal differences, but it does not replace calibration or a documented comparison on site. We distinguish measured findings from explanations that still need verification. Crop performance and savings are not established by a data audit alone.
