Seeding Pot self watering

Hi Community, I created for my cultivation tray some pots with 40 mm diameter at the bottom and 45 mm diameter at the top. You can use it perfectly for the trays where also some Cocos Soil tablets with ~35 mm diameter can be placed. If place on the bottom some cotton and you put some water in the tray the Pots will be self watering. Have Fun. Boost Me
