"No More Questioning Measurement Validity": Inside T&G Fresh's First Season with Source
T&G Fresh grows tomatoes across 25 hectares spread over three locations in New Zealand. Like most multi-site operations, keeping every location reading from the same picture of crop health was harder than it sounds, and last season that gap became impossible to ignore.
The Challenges
No shared source of truth across sites.
Each of T&G Fresh's three locations tracked its own crop data, with no single place to bring it together. Comparing how one site's crop balance stacked up against another meant reconciling different spreadsheets and different habits, not a shared view. For Head Grower Chris Cowie, that made it difficult to know whether a reading from one site meant the same thing at another.
Crop balance came down to a judgment call.
Deciding whether a crop's energy was in balance, generative or vegetative, had always relied on experience and a subjective read of the plant. Without a consistent, trusted number behind that read, measurement validity was constantly questioned. A grower's call was only ever as strong as the argument they could make for it.
How Source Workspace Helped
Catching the surplus before it costs yield.
In T&G Fresh's first season with Source, the Plant Balance KPI picked up a crop energy surplus starting to build. Because the signal was visible in time, Chris was able to make a timely pruning decision, acting on the data instead of waiting to see if the plant's behavior confirmed a hunch.
Showing the numbers.
By the March 2026 season review, standardised dashboards had replaced manual reporting in T&G Fresh's weekly grower meetings. The same view, built from the same data, was now in front of every grower across the operation. That consistency did what no individual argument could: measurement validity stopped being something the team had to debate.
Results
Building a Standard Across Sites
Beyond the surplus catch itself, T&G Fresh came out of the season with something more durable: a shared standard.
Because the Plant Balance KPI and Workspace dashboards were consistent across all three locations from the start, the same standard was already in place everywhere, not something that had to be introduced site by site after the fact. Every grower, at every location, works from the same signal.
For a business managing multiple sites, that consistency is what turns one good decision into a repeatable one.
