I just had this conversation with Ed Zahler of I CAN'T BELIEVE IT IS A DIP. I have known this for years as it has been my experience that the dip pods produce more seeds that tet pods. It really depends on the parents. The most I have gotten out of a tet pod is around 15 seeds. With the dips, that is the minimum number of seeds. I tend not to load up a plant with seed pods for several reasons: I have heard that it can stress a plant and you will have fewer flowers the next year. I really don't know it this is true, because a friend of mine in York, PA, loads his plants with seed pods every year and the following year there are plenty of blooms waiting to be pollinated. The other reason I don't set a lot of pods is I don't have all the room in the world to plant seeds. I will be curious to hear what other people have to say about seed pods on a clump.
