The Kratky method is a hydroponic growing method discovered by B. A. Kratky, an Emeritus Horticulturist at the University of Hawaiʻi at Mānoa. The Kratky process is a passive hydroponic technique for growing plants. The plants are placed in a net cup and are suspended above a nutrient-enriched water reservoir. This method is a non-circulating approach. It does not require any use of an air pump, air stone, electricity, added oxygen, or any other electrical or manual equipment. It would be best to have a big enough reservoir filled with water and the correct amount of added nutrients. Once the pool runs dry, your plant is ready for harvest. The Kratky method is perfect for commercial and genuine backyard hobbyists, and it requires very low maintenance.

First of all, let us define what a Growing medium is? In traditional gardening, the growing medium is a soil-like substance that supports a plant's roots as it continues to grow. The soil-like substance usually has organic-rich nutrients that continue to feed the plant until it reaches full maturity. In hydroponic gardening, the growing -medium can be pretty much anything that can support a plant's roots. Some of the most popular types of growing mediums are Rockwool, Cocopeat or Coco coir, Hydroton clay pellets, Perlite, Oasis cubes, Sure to Grow, Starter plugs, Growstones, and Gravel, just to name a few. I will add a page to show you the different types of growing mediums.

What is considered Organic Gardening? Or better yet, what is Certified Organic Gardening? According to the National Organic Program, to be certified organic, a garden must meet a set of stringent rules. Some of the guidelines for growing produce are aimed at a minimum impact on the environment. They say here that a natural supply of nutrients is delivered to the plant by microorganisms and other environmental-friendly pest and disease control methods. For the backyard hobbyist, organic gardening is growing plants without harsh chemicals and dangerous pesticides.

What Size Container Do I Need?

The size of the container will vary depending on what type of plant you are trying to grow. If you are interested in growing a lettuce plant, from my successful experience I recommend that you should use a container that holds at least one gallon of nutrient-enriched solutions. This one-gallon size is perfect for putting your plant on auto grow mode.
