This week in Joey’s class we are learning to grow our own junk hydroponics. We have a choice on what we want to grow in the hydroponics. Hydroponics are a series of different types of growing water systems like the Kracky system its very simple. The system typically consists of a container like a plastic tub filled with nutrient-rich water. Plants are placed in net pots that rest on top of the container, with their roots submerged in the nutrient solution.
