Horti Syfiori
Horti Syfiori — natural foliar nutrition for sustainable greenhouse growing
Awarded Fertiliser Brand of the Year, Netherlands 2026
Shortlisted among Europe’s Top Plant Nutrition Solutions, 2025
What it is
Horti Syfiori is a natural foliar biostimulant designed specifically for greenhouse crops.
It strengthens plants from the inside out, supporting overall physiology with a clear focus on total plant health.
Main benefits
Better crop quality and higher yield
Supports vital processes such as photosynthesis and nutrient uptake, improving both quantity and quality of harvests.Lower disease and pest pressure
Helps reduce powdery mildew and lowers pressure from thrips, spider mites, and aphids.Stronger stress resistance
Plants tolerate heat, drought, and diseases more effectively—particularly useful in controlled greenhouse environments.Sustainable and eco‑friendly
Uses a natural formula with a lower environmental footprint than traditional synthetic fertilizers.More efficient nutrient absorption
Encourages plants to use nutrients better, reducing the risk of deficiencies and over‑fertilisation.Proven results within about 22 weeks
Field trials show significant improvements in disease pressure, production strength, and yield—up to about 20% higher.
Use now to build stronger crops today and set up a cleaner, problem‑free start next season.
How it works, in practice
Composition
A system with three components:Master Mix
Master Calcium Plus
Master Potassium Sulphate Plus
Dosage
Typically 1 litre per 1,000 litres of water per hectare for lower crops, with guidance provided for taller crops.Application
Applied as a separate foliar spray.
With ongoing use, plants gradually build resistance, allowing growers to reduce reliance on chemical crop protection.Support
Producers offer monitoring, guidance, and coaching through implementation.
These practical details and the 1 L vs. 5 L pricing are listed directly on the product site.
Product options
Below are the main purchasable formats shown on the product page.
Ready to buy — small set
Why this option is ideal to start
Low upfront cost for trial or small-scale use.
Weekly dosage is 1 L per 1,000 L water per hectare; works out to roughly €0.0075 per m² per week, as shown on the product page, making it easy to budget. (syfiori.nl)
Same formula and system as the larger set, with professional-level support available.
Tradeoffs to note
Smaller volume means more frequent reordering if used widely across a large greenhouse.
As with any foliar system, application timing and spray coverage matter; growers should follow guidance and monitoring to maximise results.
Ready to buy — larger set
Why choose the larger set
Better unit pricing for bigger operations, shown as €0.0070 per m² per week on the site. (syfiori.nl)
Reduces the need to order as frequently compared to the 1 L set—useful for growers already committed to weekly sprays.
Same system benefits and professional coaching.
Tradeoffs to note
Higher upfront cost than the 1 L option.
Requires adequate storage space and handling for the larger volume.
Background, recognition, and credibility
International patent
The system is protected by an international patent (listed as e.g. 2026436), underscoring the innovative approach behind the product.Origin in aquatic plant nutrition, expanded to greenhouse crops
Developed originally for aquaria and then adapted to greenhouse cultivation to optimise leaf‑level physiological processes.Industry recognition
Listed among Europe’s top plant nutrition solutions and highlighted on the main Syfiori site for professional greenhouse use. (syfiori.nl)
These points strengthen the product’s credibility for professional growers, distributors, or investors evaluating a natural biostimulant with documented backing.
Typical use case
Initial setup
Order the 1 L or 5 L set depending on scale, then plan weekly foliar sprays at the recommended dosage.Ongoing application
Apply as a separate spray to build resistance, reduce disease/pest pressure, and gradually transition away from heavier chemical crop protection.Monitoring and coaching
Use the offered support to track crop response, make adjustments, and demonstrate progress over time.Longer‑term benefit
Over ~22 weeks, expect visibility of stronger plants, reduced disease pressure, and potentially up to ~20% increased yield, based on field observations and trials reported by the producer.
Grower feedback
A grower testimonial highlights real‑world benefits:
Perla Nova, Zevenhuizen reported stronger, thicker leaves, more vibrant flowers, improved root growth, no spray residue, and more efficient use of nutrients—leading to a strong recommendation for the product.
This kind of feedback supports the claims about plant robustness, quality, and efficiency of resource use. (syfiori.nl)
Clear visual advantages shown in trials
Images and reports from greenhouse use show:
Thicker stems and stronger, healthier plants
Larger flowers and more uniform growth
Noticeable difference compared to untreated sections, especially in disease-prone crops
These documented visual differences back up the system’s purpose: to make crops stronger and healthier with natural foliar nutrition.
