The white cover is capulary matting. I use it in most of my greenhouse tables. It stays damp all the time and keeps up the humidity and can water plants from the bottom. Here I used it to protect the liner as well as to make sure all parts of the table are kept wet. At times some slight areas of the table will not get water and this will wick the water up and stay damp even on the slightly uneven areas.
