We Produce High Quality Fertiliser...
...plant aids and soil additives that are mixed, filled and packed in our own production halls in Kerkrade, the Netherlands. We have been doing this with love and passion since 1996.
In-depth research into the secrets of plant metabolism has led to HESI successfully developing an optimally balanced composition for each phase of the plant life cycle. The result is a range of fertilisers per specific growth phase, but for universal use instead of a designated fertiliser for every single plant species! Additional added vital substances such as vitamins and amino acids allow the plants to increase their energy. This makes growing indoor, garden and patio plants a real pleasure.
Hesi is a thriving international company with a global reach including Europe, America, Asia and South America, with a personal touch and a down-to-earth approach. Check out the retail section to find a retailer close to you.
Only when the end user is satisfied, we are satisfied too!

Once Upon A Time...

The Name
“How shall we name our company?” said Henk. After some brainstorming and discussing, they remembered that both their passion is there, so why not combine their names? That is how the name 'HESI' derived: a combination of the given names of the company's two founders: HE stands for Henk and SI - for Siglinde.

To This Day
Hesi has helped more than 1000 companies and individuals with their solutions. What is their secret? To listen closely and to exceed every customer’s expectations with real ingredients, in-house production & personal client contact. The reason they started, the smile on their friends' face, is what kept them going all these years.

The Vision
But the story doesn't end here, Hesi is motivated to keep growing. To innovate new products and solutions, that will help you to grow bigger yields with less effort.
