You should use a rhizome clip for stabilization, not the spike.
Large, mature Phalaenopsis can be allowed to rebloom on the same spike. This can be done by cutting the spike back to a 1/2" above the lowest node. Sometimes they do it from the tip of the spike. While the first set of flowers are blooming, they spike suddenly starts elongating making more buds,
The layer is alright but the prior is only a good idea on a vigorous mature plant. With younger plants, energy is best putbto use byvcreating more roots and leaves instead of more flowers.
