Fertilizers for Licensed Growers

You already know which chemistry works in your grow. FertiQi supplies it directly from production – without the brand premium, without the marketing markup and without minimum orders that force you to stockpile.

• 30–50% average cost reduction compared with branded retail inputs at comparable volumes
• 25L minimum for a trial on any product
• 8+ EU countries served, fast delivery from our warehouses in Germany and Barcelona

Fertilizers for licensed growers, direct from the producer

A significant part of the price of a branded bottle goes to packaging design, trade shows, marketing and distributor margins. The chemistry inside the bottle is the part we supply – directly, without the layers on top.

FertiQi is a fertilizer producer based in Vilassar de Mar, Barcelona. We formulate, produce and fill fertilizers, biostimulants and specialty actives in-house, with a warehouse and distribution centre in Wachtendonk, Germany for fast EU-wide delivery. We already work with licensed growers in Germany, Spain and Switzerland. We do not sell to end consumers.

What makes us different

• Same active chemistry as the brands you know, made at source
• No large minimums – start with 25L and scale to IBC as you grow
• We think along with you – custom feed programmes, water analysis and problem solving
• Small batches and custom runs with quick turnarounds

Our fertilizers for licensed growers

From base nutrition to specialty actives: you can run your current programme with our products, or we help you design a better one.

Base nutrition

Mineral and bio-mineral NPK – liquid or powder, formulated to your water analysis – for coco, soil, hydro and aeroponic systems. Plus mono nutrients (N27, K20, P20, Ca15, Mg, Fe, TraceMix) for precise EC and element correction, CaMg Boost for RO or soft water, and a liquid root product. From 100L or 100kg.

Bloom boosters and additives

PK boosters, all-in-one bloom stimulators, P-boost, K-boost and shooting powder for a late-bloom PK push. From 25L.

Orthosilicic acid (OSA) and specialty actives

Stabilised orthosilicic acid (Si(OH)₄) at 2.56% – the form of silicon plants take up – kept in its monomeric form. Our stabilised OSA has been on the market since 2012. At 15ml per 100L, a 25L bulk order covers around 166,600 litres of nutrient solution. Also available: root stimulators, amino acids, enzymes, biostimulants, H₂O₂ and N-boost. From 25L.

pH management and water

Phosphoric acid (H₃PO₄) in multiple concentrations (20%, 45%, 59%, 75% and higher on request), nitric acid (HNO₃), potassium hydroxide (KOH) and citric acid for organic programmes. Anti-chlorine and antiscalant agents for irrigation hygiene. From 25L to IBC.

Humic/fulvic acids, seaweed extracts, living soil substrates and organic inputs are also available. All products can also be filled as private label.

Switch without disrupting your cycle

1. Tell us what you currently use – products, feeding schedule, water source, substrate and system type.
2. We propose equivalent products – a side-by-side comparison of active compounds, concentrations and dose volumes for you to verify.
3. Trial batch of 25L per product – test one product or the full programme, usually shipped within a week, with no volume commitment.
4. First full order and feed schedule – repeat supply at volume pricing with a tailored feed programme.

Custom feed programme

We design a complete feed schedule matched to your grow – coco, hydro, living soil or NFT, 50 plants or 500. Send us:

• Substrate and system
• Water analysis (EC/pH)
• Light schedule (PPFD/DLI)
• Genetics and targets
• Current products used
• Cycle length

We send you a complete feed schedule and product proposal. And if something is not working mid-cycle, call us – we are a small team and we pick up.

Expertise and quality

• We come from the industry – our team has grown professionally, managed licensed operations and built feeding programmes.
• Water quality and system hygiene – anti-chlorine, antiscalant and pH products for professional irrigation systems.
• Organic and living soil – pre-charged living soil, mycorrhizae, organic NPK, humic/fulvic acids and enzyme complexes.
• No ceiling on volume – independent quality testing of every batch; raw materials from established European suppliers.

Minimum order quantities

• 25L – specialty actives, OSA and boosters
• 100L – standard base nutrition formulas
• 200L – private label custom runs
