First, place a layer of chestnut-sized stones on the bottom of the porcelain basin. The purpose of placing the stones is to make a drainage layer, so don't place them too densely. Then, spread a layer of hay or dried leaves on the stones, and then sprinkle a layer of 2cm thick coarse sand. After the basin bottom waterproof layer is completed, a drainage layer should also be made around the basin wall. Use a hard paper shell to form a tube, the inner diameter of the paper tube is about 1cm smaller than the inner diameter of the porcelain basin. After the paper tube is finished, place it vertically in a porcelain basin, fill the paper tube with culture soil, and put coarse sand between the paper tube and the basin wall. Pull out the paper tube slowly, and compact the soil with your hands or tools. Porcelain pots treated in this way have good permeability, and there is no need to spend time perforating at the bottom of the porcelain pots, and it is also prone to cracks, and it is more convenient to clean than clay pots and pottery pots, and it is not easy to pollute the environment.
