All the pods have turned brown as one can see compared to the green left in the stems. One advantage of using the Fast Plant to study biology is the availability of free good literature. There is an instruction sheet on seeds and harvesting. All the pods appear to be ready to pluck, put in a zip lock bag, broked up by hand, and the seeds separated according to the instructions. Some pods only have one seed and some have a dozen. The seed content varied from pod to pod.
