يتبع احتياج المياه معيار FAO: تبخر-نتح المحصول ETc = ETo × Kc، مع التبخر-نتح المرجعي وفق Penman-Monteith، وبالنسبة لهولندا، معيار Makkink الخاص بـ KNMI. توازن ماء التربة (TAW، RAW، فترة الري) يأتي من الدليل نفسه FAO-56. تتبع الملوحة نموذج Maas وHoffman، وتتبع مجموع الحرارة نموذج McMaster وWilhelm. للنمو تحت الزجاج نحيل إلى عمل Stanghellini.
