What granular growing media are commonly used for hydroponic flowers

Besides maifan stone, there are other granular media commonly used for hydroponic flowers, including ceramsite, orchid stone, stone grains, and more. Let's take a look at them together below.

Ceramsite

Ceramsite is a type of artificial lightweight aggregate, hard on the outside, with a glaze layer on the surface that blocks water and retains air, and a microporous, porous ceramic granular interior. The type made mainly from sea mud clay is called clay ceramsite. Clay ceramsite is non-toxic, odorless, corrosion-resistant, and has excellent adsorption properties. It is suitable for purifying all kinds of water quality, is very beneficial for the attachment and growth of microorganisms, and is very widely used in soilless flower cultivation, potted flowers, and bonsai cultivation.

Orchid stone

Orchid stone, also known as fired soil or volcanic expanded stone, is often used for growing orchids. It has good air permeability and water retention, and is rich in potassium.

Stone grains

Stone grains are particles the size of peanuts or soybeans made by processing natural stone. These granular media are generally alkaline, so they should be rinsed clean with water before use. They are used as fixing and decorative materials for hydroponic flowers.

Besides plants with unattractive roots and plants that need to be fixed, which require granular media, newly sown small woody plants and palm family plants are also quite interesting and lovely to grow hydroponically with granular media.
