With more than 25 years of experience in the horticulture and crop input sectors, Eric brings a strong track record in international business development, commercial leadership and strategic growth. Throughout his career, he has worked in both large multinational organisations and family-owned businesses, consistently driving performance in globally oriented and innovation-driven environments.

Eric Lekkerkerk succeeds Hub Janssen, who stepped down as Managing Director at the end of January 2026.

Anders Espe Kristensen, Executive Vice President of the Systems Division at ROCKWOOL Group, commented:
"We are very pleased to welcome Eric to Grodan. His deep industry knowledge, combined with his commercial and leadership experience, makes him well positioned to lead Grodan into its next phase. We look forward to further strengthening our position in precision growing and supporting our customers worldwide."

"Grodan has a strong heritage and a clear leadership position in growing solutions for the horticulture industry. At a time when growers are under increasing pressure to use resources such as water and energy more efficiently, our solutions can make a meaningful difference. I am very excited to be rejoining the team and, together, we will build on Grodan’s strengths, support our customers in the transition to more sustainable and future-proof growing practices, and drive further growth."
