What Hesi Plantenvoeding does

Hesi Plantenvoeding B.V. is a Dutch plant nutrition manufacturer founded in 1996 by Henk and Siglinde, whose initials form the brand name. The company designs and produces a range of liquid fertilisers, boosters, and starter packs for three cultivation substrates — Soil, Hydro, and Coco — alongside a Bio line of 100% natural, biological, and vegan products. The portfolio spans primary nutrient formulations (TNT Complex, Bloom Complex, Hydro Bloom, Coco, HousePlant Elixir, OrchiVit, Bio Grow, Bio Bloom, PK 13/14), functional boosters (Root Complex, SuperVit, PowerZyme, Boost, Hesilicio, CalMag), and bundled packs (StarterBox, Hesi Pack), with proprietary formulation features such as a 3% colloidal orthosilicic acid delivery system (Hesilicio), Trichoderma-derived enzyme extracts (PowerZyme), and a 25-component bio-stimulant (SuperVit). Recent launches include a balcony-focused fertiliser (2024) and silicon and calcium-magnesium boosters (2025).

All production is conducted in-house at the company's Kerkrade facility in the Netherlands, with mixing, packaging, labelling, and shipping handled by the Hesi team. The company operates a wholesale and retailer-led go-to-market model with no direct-to-consumer e-commerce store, distributing through wholesalers and a retailer network that covers more than 40 countries. Pricing is not publicly disclosed; customers must request price lists via the contact form. The end-customer base is fragmented across hobby gardeners, professional growers, and retailers, with a small additional revenue stream from branded merchandise (organic cotton T-shirts) sold via Etsy in Europe. The company holds no external investment, operates as a privately held family-founded business, and maintains a Grüner Punkt environmental compliance certification for the DACH region.
