WebApr 6, 2024 · Leave the chia seeds to soak. After around 2 minutes, the seeds should have absorbed some of the water and grown in size. They will appear as though they have grown a gel around them. The seeds will be encased in a thin transparent layer that is slimy to the touch. But, it isn’t quite done yet. WebBoth the matric and the osmotic components of the soil-water potential are directly involved in soil-water movement to germinating seeds. Seeds immersed in solutions and in saturated soils respond equally to equal changes in these two components, provided their membranes are intact and fully active.
