For multiflorals, when the spike begins to emerge, I never change the plants orientation towards the light. After the first flower opens, it should be facing straight up and down, but as the new buds begin to weigh the spike down, the first flower will begin to pitch forward. This is when I add a wire support to the spike. I place the wire support on the far side of the fan and it curves slightly to catch the spike just above the first flower. I adjust the wire so that the first flower is straight up and down again. I also make sure the buds are alternating properly and might gently move them to make it so. This seems to work Ok for 3-5 flowers, but I suspect you would need additional support for more flowers. For other paphs, I just let things happen naturally, but if the weight of the flower bends the spike, I will add support to return it to its natural presentation. For plants like delenatii, where you can have two flowers that are opening in quick succession, I use very thin wire supports to keeps the buds apart as much as possible. I let the first flower open, then I turn the plant so the unopened bud is facing the light. After both flowers are open I remove the wire supports. I do even more manipulation of phalaenopsis spikes to get the presentation that I want. Most of the great looking flower spikes in orchid shows have received a little help. Mike
