Very interesting video and information. One thing I might complain about is his statement right at the end that "store bought" seeds are sterile. That simply isn't true. First of all, he means hybrid seeds. All "store-bought" seeds are not hybrids. Hybrid seeds are not sterile. Hybrid cucumber seeds, for instance, will grow cucumbers but they won't be the hybrid variety that you originally planted. You don't know what they will be like because they will have DNA from the varieties that were used in the cross-pollination to create the hybrid. They might be tasty, they might not be. You just don't know how the quality will turn out but they WILL be cucumbers and they will grow and produce.
It is true that big companies are working on their terminator technology for their big agri-seed hybrids but those are not available to home gardeners. Any hybrid seed that we can buy is not sterile.
Over all, I enjoyed the video. I just wish folks would get their facts straight!
