More Information About 3D Model :
This compilation of materials—ROCKWOOL, FOAM SPONGE, and NET POT CUP MESH—constitutes the foundational components of the substrate and containment infrastructure utilized in controlled environment agriculture (CEA), primarily within hydroponic and aeroponic systems. These integrated elements are designed to replace traditional soil substrates, providing inert physical support, optimal root zone aeration, and regulated moisture delivery for plant propagation and sustained growth.

### Growing Media Substrates

The designated media are highly specialized, non-soil materials categorized by their high porosity, chemical inertness, and stable structure, critical features for maintaining a balanced root environment in solution-based cultivation.

#### Rockwool (Stonewool)
Rockwool, often referred to as stonewool, is an amorphous, fibrous material derived from heating basalt rock or diabase to temperatures exceeding 1,600°C, then spinning the molten liquid into fine fibers, which are subsequently compressed into cubes, blocks, or plugs. This medium is sterile upon manufacturing and exhibits a unique characteristic of holding vast quantities of water (typically up to 80% saturation by volume) while simultaneously retaining a substantial percentage of air space (15–25% total volume), thereby mitigating the risk of root anoxia. Rockwool is predominantly utilized in commercial hydroponics for starting seeds and cuttings due to its consistent structure and ability to maintain a stable environment once saturated. While chemically inert, new Rockwool substrates possess a high pH and typically require an initial conditioning soak in a low-pH solution before use.

#### Polyurethane (PU) Foam Sponges
Polyurethane (PU) foam sponges represent an alternative synthetic propagation medium. These open-cell polymer matrices are characterized by their uniformity, lightweight nature, and defined pore size. PU sponges are cut into small cubes or plugs specifically designed for seedling establishment. They offer consistent moisture retention and rapid root penetration, often utilized interchangeably with Rockwool, particularly in systems prioritizing ease of handling, cleanliness, and resistance to degradation. The structure of the foam provides excellent resilience against mechanical compression and vibration.

### Containment System: Net Pots, Cups, and Mesh

The Net Pot Cup Mesh system serves as the structural container that physically anchors the growing medium (Rockwool or Foam Sponge) and the plant crown, positioning the root zone optimally within the hydroponic reservoir or channel.

#### Structure and Function
Net pots are typically fabricated from durable, non-reactive plastics, such as High-Density Polyethylene (HDPE) or Polypropylene (PP). Their defining characteristic is the presence of numerous openings, or “mesh” slits, covering the sides and bottom of the cup. This design facilitates maximum interaction between the root mass and the circulating nutrient solution.

The primary functions of the net pot include:
1. Physical Support: Holding the fragile propagation medium (plug) and the young plant upright.
2. Root Excursion: Allowing roots to rapidly grow through the mesh openings and into the free volume of the nutrient solution, transitioning from the solid medium to the liquid environment.
3. Hydroponic Interface: Acting as the crucial interface between the plant and the system, ensuring the crown remains above the moisture line while the developing roots are fully submerged or exposed to mist/film, depending on the cultivation technique (e.g., Deep Water Culture, Nutrient Film Technique, or Ebb and Flow).

### Integration and Application

The full system assembly involves placing a pre-rooted propagation cube (Rockwool or PU sponge) inside a suitable net pot. This assembly is then inserted into corresponding holes on the lids of reservoirs (as in DWC) or integrated into the delivery channels of NFT or vertical farming units. The combined use of inert media and open-mesh containers ensures sterility, mitigates the risk of soilborne diseases, and provides cultivators precise control over nutrient concentration, temperature, and oxygen saturation within the root environment. This precision is instrumental in maximizing plant growth rate, yield consistency, and resource efficiency.
