01 — Background
The Evolution of Greenhouse Tomato Lighting
Moving from HPS to LED changes more than the fixture. It changes how light, heat and humidity must be managed together.
01
Engineering Better Light for Tomato Production

Supplemental lighting has become essential for year round tomato production, especially in regions with limited winter sunlight.
For decades, HPS lighting was widely used in commercial greenhouses.
Today, growers are transitioning to LED growlights for tomatoes due to higherefficiency, longer lifetime, and precise spectrum control.
Unlike HPS, LEDs produce less radiant heat, creating a new growing environment that requires better integration of lighting
climate management, and plant control.
Richland treats tomato grow lighting as part of the complete greenhouse operating system not as a standalone equipment decision.

02
Different wavelengths influence tomato
growth in different ways:
Red Light (660 nm)
Supports photosynthesis, biomass
production, and fruit development.
Blue Light (450 nm)
Promotes compact plant structure, healthy
leaves, and efficient gas exchange.
Far-Red Light (730 nm)
Improves canopy penetration and influences plant architecture.
Dynamic Spectrum Control
Adjusting spectrum and intensity based on
crop stage helps optimize growth, uniformity, and production efficiency.
The Science of Light Spectrum
02 — Cultivation challenges
Challenges in professional tomato cultivation
Light must be engineered around a tall, dynamic greenhouse crop.
01
Managing Climate and Humidity Under LED Lighting
LED grow lights change the greenhouse climate balance.
Unlike HPS lighting, LEDs produce significantly less radiant heat,
which affects crop temperature, transpiration, and humidity behavior.
Successful tomato production requires an integrated
approach combining:
active dehumidification
strategic heating
airflow management
climate control systems
This allows growers to maintain optimal humidity levels, improve plant performance, and reduce energy consumption.

02
Achieving Uniform Canopy Lighting
Commercial tomato crops develop dense, high wire canopies
where light distribution becomes critical.
Traditional toplighting often creates strong intensity
at the upper canopy while limiting photon availability for lower leaves.
Richland LED solutions combine optimized top-lighting and
intercanopy strategies to deliver more balanced
PPFD distribution throughout the plant profile, improving
light-use efficiency and supporting consistent crop performance.
03
Optimizing Light Spectrum and Intensity
Tomato cultivation lighting must support changing crop requirements from vegetative development through flowering and fruit production.
Intensity, spectrum and photoperiod should be considered together.

Maintaining Consistent Yield and Fruit Quality
Maintaining consistent yield and fruit quality
becomes more challenging when light availability,
climate conditions, and crop load change
throughout the season.
Lighting strategy must stay aligned with crop
demand and greenhouse climate capacity
to support stable, predictable production.
BALANCED CROP RESPONSE
when light, climate and crop load work together,
the crop performs consistently
03 — Engineering solutions
Engineering Tomato Lighting Around Crop Requirements
Tomato lighting performance depends on how the complete operating strategy responds to the crop.
Solution 01
Crop-Specific Spectrum Strategy
Developing the right spectrum for commercial tomato production
Tomato plants respond differently to each wavelength of light.
Effective greenhouse tomato lighting requires more than increase in
light intensity it requires the right spectral balance throughout
the crop cycle.
Richland full-spectrum LED solutions combine blue, red, and
far-red wavelengths to support photosynthesis, canopy development,
and fruit production.

Solution 02
Precision PPFD Distribution
Simulation-based lighting optimization adjusts
fixture placement, spacing, mounting height, and
greenhouse layout to achieve uniform PPFD across
the entire crop canopy.
Design around the canopy and row layout not only the average output of a fixture.
Solution 03

Interlighting Technology
LED modules positioned inside the tomato canopy can deliver supplemental light to shaded leaves, improving lower-canopy illumination and utilization of available light.

Integrated Climate Management
Efficient tomato grow lights must operate as part of the greenhouse climate strategy. Dehumidification, airflow, heating and environmental controls should respond to the changed heat balance under LED lighting.
Integrate lighting decisions with the conditions that maintain transpiration and crop performance.
Coordinated lighting and climate control support consistenttranspiration, growth and efficient energy use.

06 — PERFORMANCE VALIDATION

DATA-DRIVEN PERFORMANCE
From lighting design to measurable tomato crop performance.
Commercial tomato lighting should be evaluated beyond fixture efficiency alone. Performance is assessed through photon
delivery to the productive canopy, climate interaction and
crop response under real production conditions.
Key indicators can include PPFD uniformity, DLI, vertical canopylight distribution, leaf and canopy temperature, transpiration
response, fruit set, fruit quality and yield consistency.
Monitoring these parameters helps refine lighting, climate and
irrigation strategies around actual crop demand as canopy
density, solar radiation and fruit load change throughout the
production cycle.
