One German woman and one Dutch man fell in love. Not just with each other, but also with taking care of plants. Siglinde was working as a scientist, working in a lab on many different projects, every singly day. One side project, was to create a fertiliser of a very high quality. Only the best components were considered for this passion-project, and no costs or efforts were spared. This same recipe with the same quality standard, is still being used today. They saw friends who where into cultivation and they were not getting the results they wanted whilst growing. These cultivators were challenged and desperately needed a fertiliser, that would be of high quality… for a fair price. Henk & Siglinde saw no other option than to support their friends. Combining both their skills, Siglinde’s chemistry background and Henk’s passion for helping people. With their devotion, experience and motivation, they went on this journey together. Driven by their joy of helping others, they said goodbye to their old lives, and never looked back. They kept growing and growing, nothing could stop them. At one point however, they couldn't do all the work alone anymore. That was the point they started to grow the Hesi team. The team that works together every day in order to create and deliver the best plant fertiliser for your plants.
