How natural solutions from Hortus Supplies International, like Supramino, BioCarb, X-Hance, Strength and Flower Sea Boost help crops perform better.

Growers today face the dual challenge of increasing production while managing stress factors such as drought, heat, salinity, and declining soil fertility. Biostimulants are playing an increasingly important role in meeting these challenges. At Hortus Supplies International, we support growers with a range of various biostimulants designed to improve plant performance.

What are Biostimulants?

Biostimulants are substances or microorganisms that stimulate natural plant processes to enhance nutrient uptake, nutrient efficiency, abiotic stress tolerance, and crop quality – independent of their own nutrient content.

Common categories include:

• Humic and fulvic acids
• Protein hydrolysates like Amino acids
• Seaweed extracts
• Beneficial microorganisms like PGPR (Plant growth-promoting rhizobacteria)
  
  Unlike traditional fertilizers, biostimulants do not feed the plant directly. Instead, they support the plant in using available resources more efficiently, improving resilience and vitality.

How Biostimulants benefit your crops

Biostimulants can be applied as a seed treatment, through fertigation, or as foliar spray, depending on the crop and the desired effect. Their functions vary widely:

• Seaweed extracts modulate growth and hormonal activity.
• Humic substances improve soil quality and nutrient availability.
• Microbial biostimulants support root–soil interactions and nutrient mobilisation.

These same principles form the foundation of the Vitalitas biostimulant portfolio from Hortus Supplies International.

Hortus VITALITAS product range

Natural Crop Care, supporting crop resilience, nutrient efficiency and soil vitality

Our portfolio is built around products that enhance plant resilience, nutrient-use efficiency and soil vitality. Each product contributes in a different manner, allowing to select a single solution or combine them for broader and more effective crop support.

Supramino – Supporting Growth and Metabolic Efficiency

Supramino is based on amino acids and peptides that enhance metabolic activity and nutrient utilisation. It is particularly suitable during phases when the crop requires additional energy to build biomass, set fruit, or recover from stress. Hortus Supramino contains the highest % of Free L-amino acids, which are easiest and quickest absorbed by the plant.

Typical role: Productivity-enhancer
• Improves nutrient efficiency
• Boosts cell activity and chlorophyll formation
• Supports uniform and vigorous growth

BioCarb & BioCarb Clear –  The Smart Carbon Source for Plants

BioCarb and BioCarb Clear support plants in improving their natural stress responses and overall vitality. They promote better photosynthesis, boost nutrient uptake, and strengthen both leaves and roots.

Why is carbon crucial for plant performance?
Carbon is the fundamental building block of all plant structures. Approximately 47% of a plant’s dry matter consists of carbon. While minerals often receive most attention in horticulture, a sufficient carbon supply is equally essential for strong growth. BioCarb provides an additional energy source in the form of carbohydrates, stimulating cellulose and lignin formation. This results in sturdier plants with increased resistance to pests and diseases. Furthermore, BioCarb supports soil life, improving nutrient availability to the crop. Biocarb is to be used in drip, while Biocarb Clear is to be used for foliar spraying.

Strength – Ca-Mg-B Foliar Support for Structural Plant Health

Strength is a balanced Ca-Mg-B foliar fertilizer designed to prevent and correct deficiencies that can weaken plant structure and reduce crop quality. Calcium supports stronger cell walls and membrane stability, magnesium is essential for chlorophyll formation and energy transfer, and boron contributes to uniform growth, pollination, and seed development.

Strength contains an optimal ratio of these nutrients, with highly absorbable calcium for fast correction of deficiencies. Regular applications improve tissue strength, resulting in more resilient leaves, flowers, and fruits with better shelf life. Strength can be applied throughout the growth cycle across a wide range of crops. Dosage may vary per crop and growing stage, and are available or upon request.

Flower Sea Boost –  Bio Chelated Trace Elements (B.C.T.)

Based on high-quality seaweed extracts, Flower Sea Boost combines energy-rich organic materials, nutrients, and bio-active elements,  that support flowering, fruit set and early development.

• Promotes balanced growth and early vigour
• Strengthens flowers and fruit formation
• Enhances uniformity and quality

Flower Sea Boost contains 4.5% (w/w) trace elements in optimal ratio, with more than 1% K2O (w/w). The nutrients are dissolved in seaweed extract, known for its anti-stress and growth-stimulating properties. Additionally, the seaweed extract optimally chelates the trace elements.

X-Hance  –  Plant and Microbiome Activator

X-Hance is a microbial biostimulant based on Bacillus velezensis, a beneficial soil bacterium widely recognised for its role in plant growth promotion and natural disease suppression. Through endophytic activity, it enhances the plant’s microbiome, improves nutrient uptake, and strengthens natural resistance against pathogens.

Key Benefits
• Improves nutrient uptake: Enhances nitrogen fixation and phosphorus/iron absorption
• Growth promotion: Stimulates root development and plant vigour
• Biocontrol activity: Naturally suppresses harmful fungi, bacteria, nematodes, and reduces incidence of soil-borne diseases
• Stress resistance: Supports tolerance to both biotic and abiotic stress
• Sustainable agriculture: Strengthens soil microbiology and reduces the need for chemical crop protection.

X-Hance contains Bacillus sp. (≥1×10⁸ CFU/ml) and Organic carbon: 5%
