The kratky method is a version of deep water culture hydroponics that just happens to eliminate all of the electrical components that can make a deep water culture setup an expensive venture to dive into. removing the pumps and air stones from a traditional deep water culture garden takes the setup from an active system to a passive one. the lack of active pumping is the key point of the kratky method, which is by definition a passively managed hydroponic garden.. With the kratky method, you actually fill your reservoir with properly conditioned water further, making sure to cover the bottom third of the net pot with water. the reason? without an airstone, your plants will need water at the start of their lives, and this technique ensures they’ll never dry out as your growing media is constantly wet..
