The effects of 3 nutrient solution formulations on the production and quality of the Sim carnation varieties, Raggio d'Sole, White Sim, Manon and Doria grown in rockwool substrate were evaluated over 12 months in northern New South Wales. The mean K: N ratio in mature carnations was 1.39: 1.00, and from the experimental results found, this ratio with 10 percent of the N as ammonium ion can be recommended in a nutrient formulation for commercial hydroponic carnation production in Australia.
