This contraption that you see here is a hydroponic system. In basic terms it grows plants by only using water. Machines like these are very important when stores are barren with fruits or vegetable like many are now. They can be kept indoors or outdoors and grow big and natural plants. In our school some of the biology teachers have them to show their students the growth of cells. So if you can you should get one to always have fresh fruit or vegetables in your home.
