Young plant growers produce large quantities of young plants for the commercial horticulture, floriculture, and landscape industries, selling to greenhouse growers, garden centers, and everyone in between. Supplying both old standards and new and innovative plant varieties, young plant growers are often at the forefront of the plant industry regarding the latest growing techniques and current market trends. Growers want to ensure with full confidence the product they offer is of consistent quality, uniformity, and vigor.

Valena™ was designed with the grower in mind, because we understand that they are continuously seeking out new and innovative ways to improve the growth of healthy plants.

Kemin offers an alternative plant growth strategy: Instead of treating the plants directly, we believe in maximizing the potential of the environment in which a plant grows at the very beginning of the plants' life, is a more powerful option. That is why we developed Valena™, a soil amendment derived from paramylon rich Euglena gracilis algae.

Valena™ gives soil an update with the latest in natural growth technology, creating an enhanced media that promotes strong, high-quality, healthy varieties, from the seedling stage to the store shelf!

Unique Sustainable Material

  • Derived from Kemin’s proprietary strain of unicellular Euglena gracilis algae
  • In-house production: E. gracilis fermented under controlled environment to produce up to 50% paramylon
  • Paramylon: unique carbohydrate storage molecule made of pure 1,3-ß-glucan.

Guaranteed Analysis:

  • Carbohydrate ≥50%
  • Crude Protein ≥20%
  • Total Nitrogen (N) ≥2%
  • Total Phosphorus (P2O5) ≥1%
  • Total Potassium (K2O) ≥0.2%

Key Benefits

Sustainable soil amendment reduction fertilizers biostimulants plant growth regulator phytohormones


plant read earlier for transplant plugs and liners ready faster 288-cells trays


Helps reduce the application of conventional fertilizers or Plant Growth Regulators


Designed to fit into any nutritional program


Helps get plants ready earlier for transplant


Valena is also for growing media manufacturers seeking the first-class ingredient to include in all-purpose professional mixes.

Smart Mode of Action

As Valena breaks down in the soil it releases a unique 1,3-ß-glucan that improves soil characteristics allowing for better plant root development and nutrient uptake that are favorable to plant growth. How? Substances like Valena are viewed as a Pathogen-Associated Molecular Patterns (PAMPs) by Pattern Recognition Receptors (PRRs)1-4 present naturally in plant cells, meaning that the presence of Valena in the soil can be mistaken for pathogens. Plants normally increase nutrient uptake to fight off potential pathogens. However, when there is an increase in nutrient uptake with no real pathogenic threat, it means the soil was optimized for the best possible nutritional uptake by the plant.5-7

Directions for Use - Nutritional Program

Dry granular powder form, easy to incorporate into your growing media at the beginning of a plant’s life cycle:

soil amendment, top dress application, nutritional program, growing media, 288-cells, greenhouse


Soil incorporated, growing media, growing mix, custom made soil, soil amendment, plant growth




One application at 1.5 g/L of growing media


At seedling or establishment phase (transplanting)


1) Sprinkle the desired rate on the top of the growing media, around the base of the growing plant

2) Follow by normal irrigation practices to hydrate and distribute the product into the growing media

3) Sub-irrigation is not recommended for this type of application



One application at 1.2 kg/cubic yard of growing media


Prior to seedling or planting


1) Incorporate the desired rate of dry granular to soil or growing media

2) Mix thoroughly until completely dispersed.


6-week Plug Trial on Vinca

The objective of the plug trial was to show the effect of Valena incorporated into the soil related to vinca plant growth. Plant growth was evaluated looking at different parameters standard to growers such as: plug stem height, plug lateral stem height, plant’s wet weight, plant’s dry weight, and plug root score. To determine and recommend the best application rate and method for growers, we performed the study at two application levels and applied Valena as either a top dress or incorporated into the soil.

plant stem height, growth, increase, soil, growing media Soil amendment, dry weight, strong plant, transplanting, plant, plugs and liners

Stem height of vinca plug plants six weeks after treatment with Valena.

Dry weight of vinca plug plants six weeks after treatment with Valena.

Both application methods, soil incorporated or top dress, showed enhanced plug growth measured by stem height.  One top dressing application of Valena at 3 g/L on vinca plugs increased dry weight biomass significantly with an average of  +75%  compared to untreated plugs: the heavier a plant is by dry weight, the more biomass the plant has, and represents an indicator of a thriving and healthy plant. 

The overall increase in each parameter indicates that amending the soil with Valena, a rich source of 1,3-ß-glucan, can help growers prime the soil to encourage efficient nutrient uptake for optimal plant growth of seedlings.
