Technology

Built around what you can't see

Every product page shows the indicative values, with a datasheet to keep or share.

Air-water balance

Air: 16%
Water: 64%
Solids: 20%

The ratio of fine to coarse materials determines how much water and air stay in the pot after irrigation.

Example: DH Pot Plant Pro 70/30

pH and EC

pH 5.5-6.2

EC0.6-0.9 mS/cm

Acidity and base fertiliser matched to the crop: low for propagation, higher for vigorous growers. Measured by the 1:1.5 volume extraction method.

Structure

0-15 mm, medium

Fine, medium or coarse, matched to pot size, crop duration and irrigation system.

Uniformity

Evenly mixed, so every pot behaves the same. Batches are checked in the laboratory.

How do I get a price?

Through a tailored quotation. Prices depend on the product, packaging, volume, delivery location and, for export, the Incoterm. That is why we prepare a quotation for every enquiry, with the price, lead time and terms for your situation.

The more complete your enquiry, the sooner we can prepare a suitable quotation. Mention, for example, your crop or application, the packaging you need, the quantity and the delivery location.

Who do you supply?

We supply businesses only: growers, landscapers and grounds maintenance contractors, garden centres and retailers, resellers and importers, in the Netherlands and for export.

A company registration or VAT number is not required for an enquiry, but it helps us respond faster. For a quotation and delivery, we will ask for your full company details.

How quickly will I hear back?

You receive a confirmation by email straight after your enquiry. We reply as soon as possible on working days. In a hurry? Give us a call: you will find our number at the bottom of every page and on the contact page.

What are the lead times?

Each packaging option on the product page shows an indicative lead time. The final lead time is stated in the quotation. We schedule bulk deliveries with you; for bespoke mixes and export, the schedule in the quotation applies.
