Powerful. Precise. Proven.
As cucumber growers face seasonal light limitations like, high humidity demands, and the need for fast, continuous production, Heliospectra provides innovative, research-backed LED lighting solutions that help you take control—improving yield, fruit quality, and operational efficiency.
Why LED lighting for
Cucumbers?
Cucumbers thrive in high-light, high-humidity environments and require careful control of light quality and intensity to ensure fast growth, proper morphology, and strong productivity. With Heliospectra’s tunable LEDs and smart control systems, you can:
Optimize light levels for consistent production
Provide supplemental light during winter without adding heat. High-intensity LEDs support uniform fruit development and predictable harvests, even in low natural light. Work with our weather forecast and locally improved (with PAR sensor) forecasts in our DLI controller, which also includes local energy prices and for Canada, peak predictions.
Just as tomato grower, cucumber growers are turning more and more into energy traders, balancing the grids and consuming energy when there is too much, switching off when there is not enough.
Support stretch and structure with tailored spectra
Adjust the light spectrum to guide elongation, leaf expansion, and flowering — achieving balanced plant architecture and improved light penetration throughout the canopy.
FR light will also help to direct the sugars (and the water) to go more to the fruit and help steer the plants significantly more generative. FR is a must have in cucumber cultivation, 5% at a latitude for example Leamington, or South of France (45°), 9% at a latitude for example The Netherlands or Poland (57°), up to 12% at a latitude for example Norway, Sweden, Finland and Iceland (65°).
Deliver the Right Light for Healthy, Productive Crops
Adapt intensity and spectrum to plant density, training methods, and growth stage to ensure each vine receives the energy it needs for yield and quality. Far-red at the right time directs sugars to the fruit, while efficient LEDs meet high light demands without adding excess heat or stressing sensitive vine crops.
Uniform, high-intensity output for greenhouse success
Deliver consistent DLI and spectral quality across your entire crop — critical for maintaining even growth in high-wire systems. High uniformity at the height of the motor of your high wire crop, 30-80cm below the top, ensures even growth, so you can optimize watering and nutrients for all your plants, not just the ones with the highest, or lowest light level. Over-watering will cause too much vegetative growth, while under-watering limits photosynthesis and will harm the sensitive leaves of the cucumber plant.
The science behind the light
With nearly 20 years of research and real-world applications, Heliospectra’s LED solutions are designed to help cucumber growers fine-tune every light variable to improve production outcomes and reduce energy waste.
Broad-spectrum LEDs for full-cycle flexibility
Our LEDs allow you to fine-tune red, blue, white, and far-red light to meet specific goals — from early vegetative vigor to full canopy development and fruiting.
Far-red for growth-stage strategies
Apply far-red light exactly when it matters — such as at the end of the day or toward the end of the growth cycle — to influence stretch, accelerate development and support generative growth without compromising energy efficiency.
Intelligent light strategies with helioCORE™
High light uniformity and efficient photon output ensure your crops receive the right intensity and duration, even in winter.
Data-driven control with real-time precision
Smart systems automate lighting based on crop needs, time of day, or environmental changes — helping you stay in control and optimize every cycle.
