EFFECTS OF GROWING MEDIA ON CHRYSANTHEMUMS GROWN IN CONTINUOUS FLOWING SOLUTIONS

Five cut chrysanthemum cultivars were grown on three tables with seven gullies on each.
One medium was used on each table so the nutrient solution from one table did not come in contact with the nutrient solution from the other table.
The media used were:

1. Precompressed peat pellet (Jiffy-7)

2. Rockwool cubes (Grodan)

3. Square plastic pots (Vefi)

The plants in Vefi and Jiffy-7 grew taller and had a higher fresh weight than plants in rockwool, while root quality of plants was the same in all media.
Plants grown in rockwool flowered sooner than plants grown in Vefi plastic pots with peat or in Jiffy-7s.
