Jar top Hydroponic Pot

This pot screws onto the top of the Lidl 80mm conserve jar. Print without supports on speed setting. The bottom of the pot needs to be printed with exposed infil, I used 20-25% grid.You will also need:An aquarium air pump, air line & small air stones and some sort of growing media, I used expanded clay pellets but most hydroponic options should work. Thread the air line through the hole in the side and down through the hole in the bottom, then connect an air stone so it just sits on the bottom of the jar, connect the other end to the air pump. If you want several pots, you will need an air splitter. Fill the pot with your medium of choice, dont use potting soil, it will just fall through and get too water logged. If you want something more dirt like, coco coir is a good option.Fill the jar with water and your hydroponic solution of choice so the water line has a small gap between the bottom of the pot. Turn on the air pump and the water should be spat up onto the pot above. Keep the air stone on even when the roots reach the water, plants need a good supply of oxygen to grow quickly. These pots work great for rooting cuttings but will also work for most plants that can be grown hydroponicaly, like lettuce.
