Hydroponics is a method of growing plants without soil, using nutrient-rich water as the growing medium. While there are several hydroponic systems available, the choice of medium plays a crucial role in providing support to the plants and facilitating nutrient absorption. Here are some different hydroponics mediums commonly used:
Expanded Clay Pellets (Hydroton): These are small, porous clay balls that provide excellent aeration and drainage for the plant roots. They are lightweight and reusable, making them popular in hydroponic systems.
Rockwool: This is a fibrous material made from molten rock spun into thin fibres. Rockwool cubes or slabs are commonly used to support plants. They have good water retention properties while providing sufficient oxygen to the roots.
Coco Coir: Coco coir is derived from coconut husks and is available in different forms, such as fibre or chips. It has excellent water retention capacity and provides good aeration to the roots. Coco coir is renewable, environmentally friendly, and suitable for a variety of hydroponic systems.
