It is important to build in an air gap in a wicking bed, between the water and the soil, with only 5-10% of the area crossing that boundary for wicking. This stops the soil from getting too sodden and helps prevent an odorous anaerobic decomposition from occurring. A badly constructed wicking bed may even have organic matter in the reservoir ...
Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.
In geology, a graded bed is a bed characterized by a systematic change in grain or clast size from bottom to top of the bed. Most commonly this takes the form of normal grading , with coarser sediments at the base, which grade upward into progressively finer ones.
Cross-beds, or "sets," are not layered horizontally and are formed by a combination of local deposition on the inclined surfaces of ripples or dunes, and local erosion. Graded beds show a gradual change in grain or clast sizes from one side of the bed to the other. A normal grading occurs where there are larger grain sizes on the older side ...

If you love the idea of chicken noodle soup but want to kick it up a notch, add tortellini instead. This soup comes together in just 30 minutes and only uses one pot, too. Get the Chicken ...
Moisture-wicking clothes adsorb the liquid sweat on the skin and spread it along the surface of the fibres by capillary attraction to the external surface of the clothing, which is exposed to drier air, and where it evaporates more quickly, in comparison with a clothing item which absorbs and retains the water in the fibres. Hence it avoids ...
