Dutch grower Jan-Willem Doelman has advanced his yellow courgette harvest by nearly a month, attributed to investments in geothermal heating and greenhouse climate control. Located in the Westland region, Doelman specializes in yellow courgettes and courgette fleurs, responding to growing demand.

He invested in geothermal energy, improving temperature stability for efficient planting. Doelman maintains a small operation, valuing teamwork and mentoring young workers like Finn Verduijn, who established Finn's Fleurs to market courgette products. Doelman aims to gradually step back from daily operations in the coming decade.
