mate that is the example of the perched water table and how it sits and how it moves ,
if you water a pot with 3 gallon of water , at the bottom it will stay wet until all the water comes down through the medium , but if i soak the bottom and have the medium draw the water up a third this will keep it nicely moist not soaked , when i water the top ill water with maybe 1 and half gallon so the pot dries equal and it does not leech out the nutrients in my soil, all this along with not having a perched water table for more than a day the soil at the bottom stay moist not soaked same as the top , an even moist container , ( i would think )
, i would also think water more often
