Common Cultivation Granular Substrate for Hydroponic Flowers
With the vigorous development of urban horticulture, hydroponic flowers have become a new favorite for home greenery due to their clean, eco-friendly, and convenient maintenance features. The cultivation substrate, as the core carrier of the hydroponic system, directly affects the development of plant roots and nutrient absorption. This article deeply analyzes the characteristics and application scenarios of three mainstream granular substrates to help you create a healthy hydroponic ecosystem.
Clay Pellets: The All-Round Medium with Porous Structure
Physical Characteristics Analysis
Clay pellets, after high-temperature firing, form a honeycomb-like structure, with each substrate having a porosity of 60%-70%. The glazed surface can effectively regulate the water permeability rate, while the internal microporous network provides an ideal breeding environment for nitrifying bacteria.
Extended Application Scenarios
In addition to the conventional fixation of hydroponic flowers, it is especially suitable for the pre-filter layer of water circulation systems, effectively adsorbing heavy metal ions. Experimental data shows that clay pellet substrates can increase the growth rate of hydroponic pothos by 23%.
Orchid Stone: Potassium Element Slow-Release Expert
Orchid stone, formed by calcining volcanic rock, has a stable pH value between 6.2-6.8 and continuously releases potassium elements, which can enhance the plant's ability to resist lodging. It is recommended to mix with clay pellets at a 1:2 ratio to create the golden proportion of substrates for orchid plants.
Stone Grit: Decorative Functional Medium
Natural stone grit, after polishing, has dual functions: the 3-5mm particle size provides stable support, and the marble texture enhances the ornamental value. Before use, it needs to be soaked in lemon acid solution for 48 hours to neutralize alkalinity, especially suitable for pairing with transparent glass containers to display the beauty of the root system.
Innovative Application Solutions for Substrate
In the early stages of hydroponic cultivation of palm plants, using a layered structure with orchid stone at the bottom and clay pellets fixed on top can increase the survival rate by 78%. For mini potted landscapes, dyed stone grit is recommended to create themed landscapes, complemented by LED lighting systems to create desktop ecological art pieces.
By scientifically proportioning different granular substrates, it is not only possible to meet the growth needs of plants but also create unique visual experiences. It is recommended to regularly monitor the pH value changes of the substrate and use hydrogen peroxide for disinfection every quarter, allowing hydroponic flowers to continue to thrive.
