Potted Darley Dale Heath cv. 'Kramers Rood'plants were grown on either 100% fertilization (0,8 µS/cm) or with 50% nutrient stress (0,4µS/cm). The amount of water recieved via top irrigation was the same for both. No significant differences were found between the treated plants and the untreated plants, in both the 100% fertilized and 50% fertilized plants. The measured parameters were plant height, plant surface, plant health score, root score, fresh weight and dry weigth.
