Tissue Culture, Growth Chambers and Walk-in Rooms

The artificial light is critical in plant propagation to substitute natural light and to provide full control of light conditions. Valoya has various solutions for  no-natural light environments like tissue culture, growth chambers and walk-in rooms.

Key features of light in propagation are good growth, energy efficiency and control of heat, intensity and photoperiod. Special needs driven by light depend on the growers needs. Processes to be affected can be for example winter dormancy (vernalization), root development or preparing plants for transplantation. Valoya can offer light spectra for both general and special purposes. We have products for low, medium and high light intensity installations. Heat of the LEDs is conducted away from the plants through the passively cooled heat sink of the fixture, which enables placing the lights very close to the plants, enabling dense vertical multi-layer installations.

Vertical Farms, Plant Factories and Multilayer Cultivation

Valoya lights are enabling new growing applications. Vertical farms and plant factories are ideal for leafy greens, herbs and young plants.

The low heat directed towards the plants enables placing the lights very close (even to 10 cm) from plants, thus enabling growing in dense vertical shelf systems. The high directional heat from High Pressure Sodium bulbs and even fluorescent tubes has limited usage of multi-tier applications in the past.

Growing in multiple layers has great potential for the future; it improves food security in areas with little or no greenhouse cultivation possibilities, it enables local vegetable production inside metropolitan areas and it gives total control of the growth environment to the growers. Multilayer growing multiplies the yields per floor footprint and gives perfect control of the growth environment.

Cultivation of Young Plants

A key reason for using Valoya light in cultivation of young plants are the possibilities to improve quality, increase capacity and to achieve a homogenous crop quality and stable production.

After propagation, plantlets, cuttings or other young plant material are transplanted to seedling cultivation. During this phase the quality of light is essential to ensure a good start in life for the plants. Various characteristics of the plants cultivated, are emphasized, in order to produce strong, healthy plants for the next phase of growing in greenhouses, on the field or in the forest. Typically this means driving strong root growth, keeping a uniform compact crop for automated planting and having strong leaves. With our wide spectrum light, we can help you to develop strong, healthy plants, increase productivity and at the same time enable energy savings.

Increasing Greenhouse Production

Many greenhouse grown vegetables and fruits benefit from artificial lights, or require artificial light for year round cultivation. Valoya lights can drive excellent flowering, crop formation and also accommodate nice working conditions both for humans and bees.

Valoya lights are used to illuminate several types of fruits, berries and vegetables. Valoya light will help to improve flowering, increase productivity and quality. Pollination is a key event in the formation of many fruits and typically pollinator insects are used in greenhouses to achieve this. Valoya has shown that its light spectra enable bumble bees to navigate, even without any natural light. This opens up new opportunities for growers, to prolong the operation time for the pollinators in winter or even use them in no-natural light environments.

Tastier Lettuce, Herbs and Microgreens

Valoya light imporoves the growing conditions for lettuce, herbs and micro-greens. Our lights are used both in traditional greenhouse environments as supplemential light, as well as in modern, no-noatural light environments like in plant factories, vertical farms, multi-layer systems etc.

Valoya lights are today used in growing leafy greens in various settings, both as supplementary light as well as the sole light source without natural light. The intensities vary from different customer's goals and go from some 30 up to 200µmol/m-2/s-1 (PAR) settings. The right Valoya spectrum drives quick biomass generation, compared to traditional lights and red/blue LEDs. Lettuce and herbs grown under Valoya lights have strong colors and taste, as well as excellent nutritional values due to higher amounts of anthocyanins and other phenolics. Plants under Valoya lights have also been shown to be more pest resistant in an independent third party research.

Improving Flowering

Artificial light is critical to the production of many flowers. They are used as photosynthetic light as well as control of day length. Valoya lights have been show to add one more layer to this, ie. driving flowering.

Valoya lights are used with flowers as supplementary lighting, as well as in sole light source in no-natural light growing environments (for example with tulips and Phalaenopsis orchids). We also have customers who, with great success, combine our lights with traditional High Pressure Sodium (HPS) fixtures. Customers' have been able to improve both productivity and flower quality. Where our customers have achieved increased productivity, energy savings have typically become a secondary priority, but a nice bonus. Flower quality and yield improvement can be seen as more grams/stem, more flowering stems, more intensive colors of flowers and stronger green colors in leaves. Valoya's spectrum for flowers can also improve compactness of plants, which reduces the need to use growth regulation chemicals. Improved quality has in many cases been achieved with lower installed power than HPS.

We have experience flowers such as roses, Phalaenopsis orchids, lilies, saintpaulias, begonia, poinsettia, hortensia, tulips, chrysanthemum, alstomeria, bromeliads.

Architectural Plant Lighting

Valoya´s architectural series lights produce white light, which is visually appealing for both plants and humans.

Valoya's architectural series light spectrum is based on Valoya's plant production spectrum, AP67. The architectural version of the AP67 spectrum has more green light, which makes it appear white to humans, while maintaining a superior plant growth spectrum. It is ideal for installations in offices, homes and public spaces as well as in botanical gardens and zoos. The Valoya architectural series lights offer different models based on light intensity and form factor required.

Valoya Arch S lights are used at Helsinki Zoo, botanical gardens and for plant walls in many locations.
