What is the nutritional difference between hydroponically grown wheatgrass and tray grown in soil?

Answer 1

There have been over 3,800 nutrients identified in living foods and likely many more that we still know nothing about. Interestingly, there are no tests for any food product that go into this level of detail. As a result, in order to assess the effectiveness of wheatgrass juice, you need to be a keen observer. Some have seen healthy results come from people using outdoor soil grown wheatgrass and indoor tray / soil grown wheatgrass. I cannot recall anyone ever indicating that they received health benefits from hydroponically grown wheatgrass. That is not to say it can't happen; it is just to say that we haven't seen it. In our experience, outdoor grown wheatgrass is a far superior product because it does not have mold problems common in indoor grown wheatgrass. This makes it much more enjoyable to use as it tastes better and does not cause adverse reactions in people (no headaches, nausea, dizziness). If you want to try out wheatgrass juice (be it outdoor, tray grown or hydroponic), it is just important to remember that you need to be your own best observer.
