What is hydroponics?
Hydroponics is a method of growing plants without soil, where the plants are instead grown in a nutrient-rich water solution.
What are the advantages of hydroponics?
Some advantages of hydroponics include faster growth rates, higher yields, efficient use of water and nutrients, and the ability to grow plants in areas with limited space or poor soil quality.
What is the Kratky method?
The Kratky method is a passive hydroponic system that requires no electricity or pumps. It involves placing plants in containers filled with a nutrient solution, allowing the roots to grow into the solution as it gradually depletes.
What is DWC hydroponics?
DWC (Deep Water Culture) is an active hydroponic system where plants are suspended in a nutrient-rich water solution with the help of an air pump. The roots are submerged in the solution, allowing for constant oxygenation.
How does water and nutrient management differ in Kratky and DWC hydroponics?
In Kratky hydroponics, the water and nutrient solution is placed in a container and left untouched until it depletes. In DWC hydroponics, the water and nutrient solution needs to be monitored and adjusted regularly to maintain proper levels.
What is the difference in plant support and root structure between Kratky and DWC hydroponics?
In Kratky hydroponics, plants rely on buoyancy and the initial nutrient solution level to support their roots. In DWC hydroponics, plants have their roots submerged in the water solution with the help of a support structure, such as a net pot.
How does maintenance and monitoring differ in Kratky and DWC hydroponics?
Kratky hydroponics requires minimal maintenance and monitoring as the nutrient solution gradually depletes. DWC hydroponics requires regular monitoring of water levels, pH, and nutrient concentrations, as well as cleaning and maintaining the air pump.
What are the advantages of Kratky hydroponics?
Some advantages of Kratky hydroponics include its simplicity, low cost, and the ability to grow plants without the need for electricity or pumps.
What are the advantages of DWC hydroponics?
Some advantages of DWC hydroponics include faster growth rates, higher yields, precise control over nutrient levels, and the ability to grow a wide variety of plants.
