Is grass grown in soil more nutritious than in water?
Actually, they are very close. A study done on the nutrient content concluded that both grasses were equal (read: Wheatgrass Nature’s Finest Medicine). Hydroponically grown grass (no soil) can benefit from nutritional products such as liquid kelp and Ocean Grown. Both add a wealth of minerals that the roots absorb by osmosis. Similarly, soil gardeners can add fertilizer to enrich the soil.Refer to the Sproutman Wheatgrass Grower SM-350 user manual for more information.
