Sometimes if you have a difficult pod setter you can put it's own pollen or something you know to be stud pollen (even if you don't really want that cross) to get the plant in the mood. Seems like once it sets one pod it's likely to set more.
If you live in areas with high temps it's important to at least know which plants are difficult pod setters. I aim to have my crossing done before the temps rise above 85*. That is often 10 in the morning and when you've got hundreds of blooms it's a job! My own Mach One has never set a pod for me. It has also never stayed in one place for long enough to come to clump strength so I have one or two plants I will not move until I see what it does. I also plant to pot up a couple of plants and bring them into the garage where it's cooler to see if that works.
I once heard Dan Trimmer suggest you bring them into the air conditioned house, light some candles and put on mood music to see if that will do the trick.
