Correct spelling for the English word "Kratky" is [kɹˈatki], [kɹˈatki], [k_ɹ_ˈa_t_k_i] (IPA phonetic alphabet).
Kratky is a term commonly used in the field of hydroponics to refer to a specific method of growing plants without the use of soil. Derived from its originator, Dr. Bernard A. Kratky, the Kratky method involves a passive hydroponic system where plants are grown in containers filled with a water and nutrient solution. Unlike other hydroponic techniques that rely on pumps and a continuous flow of nutrient solution, the Kratky method utilizes a static solution that allows plants to take up water and nutrients as needed.
In the Kratky method, plants are typically placed in containers that are partially submerged in the nutrient solution. As the plant grows and its roots begin to reach the solution, they absorb the necessary water and nutrients. The partially submerged containers create an air gap that enables sufficient oxygen to reach the root system. This passive approach eliminates the need for an active aeration system or monitoring equipment.
The Kratky method is popular among home gardeners and small-scale hydroponic growers due to its simplicity and low cost. It is particularly suitable for growing leafy greens, herbs, and smaller fruiting plants. However, it may not be well-suited for large-scale commercial production or crops with longer growing cycles. Despite its limitations, the Kratky method is highly regarded for its ease of use and success in cultivating healthy plants with minimal maintenance.
