With a production area of more than 200 ha Phalaenopsis is a very important crop. In general growers try to get as many spikes on a plant as possible to fulfill the needs of their customers. To stimulate the spiking of the Phalaenopsis at the grower a period of cooling is necessary. Light intensity also influences spiking. To make the spiking process more successful and uniform Chrysal introduced a new pre-harvest product especially for Phalaenopsis called Chrysal Viva.
