You want a maximum production and optimum quality? And do you prefer to use as less chemicals as possible? By using Pentakeep you support the crop, so the plants are stronger and more vital during the entire cultivation.

Pentakeep promotes the photosynthesis:

  • Increase of dry matter production.
  • Crop better resist against extreme conditions in greenhouse climates.

  • Increase of quality
  • Better absorption of fertilizers, water and CO2
  • A more energetic plant

The application of Pentakeep also results in a higher yield for your cultivation. The investment is only 1 euro cent/ per meter/ per week.

Pentakeep promotes the photosynthesis

Pentakeep is the only product in the world which contains 5-Aminolevulinic acid (5-ALA). This promotes photosynthesis, so the plant produces more dry matter and stimulates the growth of plants and flowers.

Pentakeep is a liquid nitrogen fertilizer to which 5-Aminolevulinic acid has been added. This amino acid promotes photosynthesis. 5-Aminolevulinic acid is an important amino acid for the plant; it plays an important role in the formation of chlorophyll (leaf green). The mix fertilizer Pentakeep contains nitrogen, manganese and trace elements. It has been proven that these supplements in combination with 5-Aminolevulinic acid creates an amplifying effect on the growth of plants.

More dry matter

5-Aminolevulinic acid is present in every living organism, in limited amounts. By extra addition to the plant, the photosynthesis and the production of sugars and dry matter increases. This is comparable with the formula; sunlight + CO2 = sugar and oxygen. It is known that extra CO2 under light conditions increases production and the process is able to continue longer, because lack of CO2 that would stop the reaction again is not an issue.

Less diseases

Addition of Pentakeep results in more and better production and a increase of quality. But it is not only production that benefits from the extra dry matter. The crop is also stronger and more vital. Because the plant becomes more energetic, it will also be less susceptible to diseases and pests.

5-Aminolevulinic Acid (5-ALA)

5-Aminolevulinic acid (5-ALA) is a molecule that occurs naturally in plants. 5-ALA is the base of life for humans, animals and plants. The substance is produced by the plant itself, but the production is limited by the speed of the metabolism. When Pentakeep is added to the plant, the metabolism is accelerated. As a result, the conversion of the single to the multiple sugars, in the chloroplasts and mitochondria, will take place continuously and there is no delay in the plant, which normally costs the necessary energy.

For plants, 5-Aminolevulinic acid is essential for the formation of chlorophyll. In addition, the plant produces more sugars and increases the absorption rate of fertilizers. ‘s

The plant burns less sugars at night, and salts in the soil penetrate less quickly. In short; stress tolerance increases.

The plant will also become more energetic. The plant can handle more than an untreated plant and is easier to steer towards the desired result. The plant is less susceptible to diseases. In addition to Pentakeep for the horti and agricultural sector, 5-Aminolevulinic acid is also used in the medical sector. Here it is used, among other things, in the treatment of skin cancer, promotes hair growth and works against anemia. Various tests are still underway to enable it to be used in more diseases.
