This page brings together the fertilizer specifications that matter for professional buyers: formats, packaging sizes, minimum order quantities, documentation, labelling and lead times. For product-specific data sheets, contact us – we send the full specification with every proposal.

• Liquid concentrates – single-part and two-part (A+B) base nutrition, boosters, biostimulants and specialty actives.
• Water-soluble powders – mineral and bio-mineral NPK powders and single-element nutrients.
• Substrates – pre-charged living soil, including a ready-to-use 11 L pot and a 50 L concentrate.
• pH and water management – phosphoric acid in several strengths, nitric acid, potassium hydroxide, citric acid, anti-chlorine and antiscalant products.

Can I test a product before I order volume?

Yes. Specialty actives, orthosilicic acid and boosters are available as 25 L trial batches, usually shipped within a week, without committing to volume.

Can you match the specification of a product I already use?

We prepare a side-by-side comparison of active compounds, concentrations and dose volumes, so you can verify the match before you switch.

Do you ship outside the EU?

In-stock products ship fast from Wachtendonk and Barcelona within the EU. International shipping is available on request; Swiss market documentation can be provided.

Which documents come with an order?

Every order includes a certificate of analysis (COA) and a Safety Data Sheet (SDS). CE and REACH documentation and EU-compliant labels are available for resale and private label products.
