Gardin Pulse - Summer Product Update
Dear valued partner,
We’re pleased to announce several updates this summer season to enhance your cultivation with plant feedback.
DPI vs DLI Now Generally Available
A new DPI vs DLI feature has graduated from beta and is now included in all subscription tiers. This functionality offers a vital view into plant photosynthesis by correlating Daily Photochemical Index (DPI) with Daily Light Integral (DLI), enabling better understanding of how light is converted into plant biomass. This insight helps you make informed decisions on a target light sum to optimise crop outcomes.
New Product Offering with Ridder
In partnership with Ridder, the Gardin app is now integrated directly into Synopta. This seamless connection enables growers to act on plant feedback within the same environment used for climate control. As Sander Barake, Product Director at Ridder, explains:
“We’ve helped growers automate climate control around the crop. This next phase is about integrating real-time crop feedback into that loop, shifting from climate control to crop control.”
Contact your local Ridder sales representative to get setup with Gardin in Synopta. This includes real time data visualisation of plant photosynthesis with climate data as well as integrated Gardin app experience to show additional insights such as alerts, targets and benchmarks.
Understanding DPI vs DLI
Plants can only photosynthesise so much each day. Choosing the right daily light sum (DLI) is critical for achieving growth targets while managing energy costs. But knowing how much growth is gained per extra mol of light has been guesswork.
DPI (Daily Productivity Index) measures how much light the plant actually uses, based on electron transport rate (ETR). As DLI increases, DPI eventually plateaus meaning the same amount of additional light gives less growth, increasing costs.
Gardin’s new DPI vs DLI tool helps identify this saturation point and automatically recommends a target DLI where DPI reaches 75% of its maximum. This allows you to capture most of the growth potential in the crop at reasonable cost and can be adjusted based on local market and energy prices.
In combination with Gardin's existing Light Advisor feature, this provides total clarity on your lighting strategy:
Set smarter, cost-effective DLI targets
Adjust the photoperiod in each greenhouse to achieve consistent productivity
Avoid under/over-lighting and reduce electricity costs
Achieve more uniform growth across zones
