Broad beans

The Early Long Pod broad beans have had masses of flowers on them for a long time now and I was wondering if they were ever going to set pods. They were planted on the 7th of June and today I noticed the first couple of pods, about 17 weeks later. There is a lot of conflicting information on plant and row space affecting the time it takes to set pods, mine are 150mm apart with rows 300mm apart. I now think that the timing is about right and it's purely a temperature thing. I've also read that cutting the growing tips encourages the pods to set. I've decided not to try this and see how they get on. Hopefully now they've started the first couple of pods will be followed by a lot more.
