Hydroponics is something new to me, and something I knew little about. If you are not familiar with it, hydroponics is a method of growing plants with nutrient rich water, instead of using soil. Soils actually retain nutrients, but are not essential for growing plants. This is a new concept to me, and I never really understood the advantages, or why someone would want to use hydroponics. I had a lot of questions until I found this book, “How To Hydroponics” This is a great resource, to view or to download, please click the link below.
