Energy savings, smarter irrigation and biostimulant performance insights at Harry Wubben Flowers.
Harry Wubben Flowers, located in Nootdorp, the Netherlands, has specialized in growing chrysanthemums for over 35 years. Today, the company primarily cultivates Santini chrysanthemums, a variety characterized by its many small blooms on a single stem. The nursery covers a total cultivation area of 60,000 m².
“We were able to reduce the lighting setting from 8 to 5, aligning the lighting with the plants’ actual needs. The impact was already visible within the first few days.”

Agronomic challenge
Like many growers, Harry Wubben Flowers relied on experience, visual observations, and climate data to make cultivation decisions. While effective in many situations, these methods could not reveal how the plants themselves were responding to changing environmental conditions in real time.
This created three key challenges:
Limited visibility into plant stress
Young Santini chrysanthemums experienced stress from artificial lighting before any visual symptoms appeared. Without direct feedback from the plants, lighting strategies were based on assumptions rather than the crop’s actual physiological needs.
Irrigation based on estimates
Irrigation decisions were made using climate conditions, substrate measurements, and grower experience. Although these are valuable indicators, they do not reveal whether the plant itself is experiencing stress or actively requires water.
No objective insight into recovery and treatment performance
After events such as high radiation, crop protection applications, or changing weather conditions, it was difficult to determine how quickly plants recovered. Likewise, the effectiveness of biostimulants could only be assessed through visual observations and experience, making objective evaluation challenging.
Results and client benefits
By continuously listening to the plants’ electrical signals with Vivent Biosignals, Harry Wubben Flowers gained a completely new layer of insight into crop performance, enabling more precise and confident cultivation decisions.
Lighting optimized to plant demand
Vivent’s plant driven insights showed that young plants were receiving more artificial lighting than they actually required. By aligning the lighting strategy with the plants’ real-time physiological needs, the grower reduced the lighting setting from level 8 to level 5. The positive effect was visible within the first few days while simultaneously reducing energy consumption.
Plant driven irrigation
Instead of relying solely on environmental data, irrigation decisions are now supported by direct feedback from the crop itself. This allows irrigation to be applied when the plants actually need it, improving water use efficiency and maintaining a healthier crop.
Objective validation of biostimulants
Vivent Biosignals made the plants’ recovery process measurable. Comparative trials clearly demonstrated that crops treated with biostimulants recovered more quickly after stress events such as spraying or periods of high radiation, providing objective evidence of product performance.
From claims to quantified proof
From reactive to predictive cultivation
Rather than responding only after visual symptoms appear, growers can now detect stress earlier and make informed interventions before crop performance is affected. This results in healthier plants, greater operational confidence, improved resource efficiency, and more consistent production throughout the growing season.
By integrating plant feedback into daily cultivation decisions, Harry Wubben Flowers was able to align climate control more closely with the actual needs of the crop. Instead of steering solely based on environmental conditions, cultivation decisions were supported by insights into how the plants themselves responded.
Why it matters
This case demonstrates the value of plant-led growing. By gaining real-time insight into plant responses, growers can optimize crop performance while reducing unnecessary use of energy and other resources. Understanding what plants need, when they need it, enables more precise decisions, improved crop quality, and more sustainable production.
Plants know best — and now they can show it.
“Before, we made decisions based on what we thought the plant was experiencing. Now, we can truly measure and understand what the plant is telling us, what it needs, and how it responds.”

Plants are talking, we let you listen in.
- Crops were not growing as strongly or consistently as expected
- Soils showed room for improvement in terms of biological activity and structure
- Yields and plant resilience were not keeping pace with increasing effort and input costs
- More inputs did not reliably translate into better outcomes
- Fields managed under the farmer’s current best practice (control)
- Adjacent fields treated with Symactiv biostimulant
- Plant Balance Index (PBI) – a real-time indicator of plant adaptation and stress
- Water status
- Nutrient uptake dynamics
- Responses to temperature, humidity, and extreme weather
- In both potatoes and tomatoes, Symactiv-treated plants spent ~7% more time in the optimal Plant Balance range
- Treated plants adapted faster and more consistently to cold, wet, hot, and dry periods
- Differences became most pronounced during weather stress and extreme conditions, where resilience matters most. Better water status under stress
- Symactiv-treated crops showed better water status during high temperatures and low humidity
- Improvements were especially visible during prolonged warm and dry periods, when untreated plants became less stable
- In potatoes, treated plants showed higher Calcium and Phosphorus availability, particularly from mid-season onwards
- In tomatoes, Nitrogen, Phosphorus, and Potassium status improved significantly in treated plants from mid-August
- Nutrient uptake was strongest under cooler and wetter conditions, aligning with Symactiv’s soil-biology-driven mode of action
- Prove product performance under real conditions
- Optimize recommendations
- Accelerate adoption with confidence

Symactiv x Vivent Biosignals x Jucker Farm AG
Quantifying the Impact of Soil Biology on Crop Performance
Symactiv is a Swiss biostimulant provider focused on restoring soil biology to turn depleted soils into productive, resilient growing systems. By rebuilding biological balance underground, Symactiv helps crops access water and nutrients more efficiently, delivering consistent performance year after year.
Jucker Farm AG, located near Pfäffikersee in Switzerland, is a progressive vegetable producer growing potatoes and tomatoes under demanding climatic conditions. Like many growers, Jucker Farm continuously evaluates new agronomic solutions that can improve crop resilience and input efficiency without adding operational complexity.
“Using Vivent’s solution, we could see when and why our biostimulant makes a difference. We were delighted to get quantified evidence of the benefits in water and nutrient status for crops treated with Symactiv.”
Philippe Schläpfer, Symactiv Co-founder and CTO
Agronomic challenge
Despite implementing regenerative practices and maintaining soils in good apparent condition, the farm faced several persistent challenges according to standard crop analysis:
Our approach
To objectively quantify the impact of Symactiv’s soil enhancer, we deployed Vivent’s plant-based sensing technology directly in the field.
Across potato and tomato trials, Vivent plant sensors were installed in:
Rather than relying solely on yield or visual assessments, Vivent Biosignals continuously monitored:
This approach allowed Symactiv and the farmer to compare treatments under identical environmental conditions, isolating the biological effect of the biostimulant.
Results and client benefits
1. Improved Plant Stability and Resilience
2. Better water status under stress
3. Enhanced nutrient uptake

Moving beyond trial-and-error toward evidence-driven agronomy
For Symactiv, these trials provided independent, plant-level evidence explaining why and when their biostimulant delivers value — strengthening both product development and customer communication. Treated plants showed substantial yield increases of approximately 15% compared to untreated plants for these specific crop cycles.
For Jucker Farm, the results validated Symactiv as a practical, field-ready solution that integrates seamlessly into existing operations while improving crop resilience.
Why it matters
This collaboration demonstrates how plant-based biosignal monitoring enables biostimulant providers and growers to move beyond trial-and-error toward evidence-driven agronomy.
