the film for a faster plant growth

LLEAF film

The LLEAF film increases the emission of red light and achieves a 20 % faster plant growth. Using the LLEAF film in greenhouses growers can achieve:

  • increased yields, efficiency and crop production.
  • even growth of plants.
  • shorter growing cycles of crop.
  • improved crop quality.
  • better nutrient supply.
  • off-season fruiting without any additional energy.
  • uses research to optimize the future food production.
  • fewer pests and diseases

The LLEAF films engineers sunlight to help the world’s crops grow bigger and faster. With an ever increasing global population, innovation is essential to provide an abundance of fresh food that is accessible for all. LLEAF empowers growers by providing technology to optimise sunlight and improve productivity. This makes the LLEAF film a sustainable solution for agricultural applications.

LLEAF film - a revolution for the agricultural and food industry

LLEAF, a company based in Sydney, Australia, developes, patents and produces light-responsive dyes when exposed to sunlight. The LLEAF technology stands for "Luminescent Light Emitting Agricultural Films" and is based on extensive research of the light spectrum. These dyes respond to sunlight by fluorescing, both absorbing and emitting light. They absorb light of one colour and emit light of another colour. Their primary function is to alter the natural light spectrum to better suit specific crops. The proprietary dyes are added to a transparent polycarbonate plastic film, creating a fluorescent film that leverages research on plant growth. LLEAF films are placed inside greenhouses between the sun and the plant. This technology adjusts the light spectrum to increase photosynthesis or simulate seasonal changes.

The result of the LLEAF technology is a significantly faster future growth (+ 20 %) of all green plants such as lettuce, cucumbers, tomatoes, basil, peppers, aubergines, Asian vegetables, strawberries or cannabis. The LLEAF film also works for herbs and flowers. Well-founded studies and research on this is already available or will be available in the near future.

Dye molecules in the polycarbonate film absorb lightphotons mainly from the green part of the spectrum, emitting red light photons in 620 nm wavelength. The LLEAF film shifts the colour spectrum, emitting more red light enhancing the prospects for future food security. This redlight favours photosynthesis and thus faster plant growth. This results in quicker crop turnover, which enhances agricultural productivity. Additionally, this technology enables growers to engage in out-of-season cultivation.

The luminescent LLEAF film also diffuses light, which reduces the occurrence of shade spots in a greenhouse. The agricultural film ensures a more even light distribution across the crop, promoting healthier and uniform plant growth. Using the LLEAF technology growers can optimize the sunlight and yield in greenhouses – without any additional energy. This leads to a more resilient agriculture against future environmental uncertainties.

Applications and use of LLEAF film

LLEAF greenhouse plastic films are designed to be used between your plants and the sunlight and are ideal for the following applications.


By using the LLEAF technology in a greenhouse growers achieve a faster plant growth and increased efficiency for lettuce and other vegetable (food). The film can be easily retrofitted to existing greenhouses or included in the production of new greenhouses. The LLEAF plastic film is installed inside greenhouses. The robust and durable LLEAF film can be easily retrofitted by screwing, clamping or hanging on existing greenhouse structures. We are happy to consult you regarding a potential installation.

Agrivoltaic - double use of land

Agrivoltaic or Agri-PV refers to the installation of photovoltaic or solar systems on agricultural land. Especially in times of climate change and the rise of alternative energy sources, agrivoltaics is an important development. Land is a scarce commodity and must be used efficiently.

Combining agri-voltaic systems with the LLEAF film has two advantages:

  • Increase in the amount of light that can be used for photovoltaics
  • Faster plant growth and higher crop underneath the solar cells

Indoor / vertical farming

Indoor farming involves growing plants not outdoors, but in a closed system - usually in greenhouses. The efficiency of the LLEAF film in indoor farming allows growers an increased profitability of cultivation for green plants, vegetables and flowers.
