More Information About 3D Model :
A large hydroponic rack netcup Nutrient Film Technique (NFT) system array represents a highly industrialized and space-efficient methodology for soilless plant cultivation, typically categorized within the domain of Controlled Environment Agriculture (CEA). This integrated system combines the high-density planting capacity of vertical racks with the efficiency of NFT delivery, utilizing netcups as the primary interface between the plants and the recirculating nutrient solution.

The defining characteristic of this system is its scale and structure. The 'rack array' consists of multi-tiered, often modular, vertical structures constructed from durable, corrosion-resistant materials such as galvanized steel or aluminum. This vertical integration drastically reduces the required floor footprint, maximizing the cultivated surface area within indoor facilities, greenhouses, or dedicated vertical farms.

The 'array' refers to the interconnected matrix of specialized horizontal channels, often called gullies or troughs, mounted upon the vertical racks. These channels are engineered with a specific, slight gradient (typically 1% to 2%) to facilitate the passive flow of the nutrient solution via gravity. Systems labeled 'large' imply commercial or industrial capacity, featuring extensive plumbing infrastructure, large nutrient reservoirs, and automated climate and dosing controls to manage hundreds or thousands of planting sites simultaneously.

The core function relies on the Nutrient Film Technique. Unlike Deep Water Culture (DWC) or media-based systems, NFT delivers nutrients by flowing a very shallow stream (a ‘film,’ usually 1–3 millimeters deep) of nutrient-rich water down the base of the growing channel. This crucial depth ensures that only the lower portion of the root mass is submerged in the solution.

This partial submersion provides dual benefits:

1. Continuous Nutrition: The roots receive consistent access to water and dissolved mineral elements.
   
2. Optimal Aeration: The upper portions of the root structure remain exposed to the air within the channel, ensuring crucial oxygen uptake (aeration). Adequate oxygenation prevents root rot and optimizes metabolic processes, leading to healthier plant growth than systems where roots are fully saturated.
   
   ### Role of Netcups and Plant Support
   
   'Netcups' (or net pots) are small, perforated containers used to support the plant structure and the initial inert growing medium (e.g., rockwool cubes, coco coir) used for propagation. The netcup is seated into pre-drilled holes in the NFT channels. As the seedling matures, its roots grow through the perforations of the netcup and extend downward, forming a dense mat that rests directly in the flowing nutrient film below. This system minimizes the need for heavy or expensive substrates, simplifying sanitation and harvesting procedures.
   
   ### Commercial Applications and Advantages
   
   Large hydroponic rack NFT arrays are highly favored for fast-cycling, high-density crops, notably leafy greens (e.g., various lettuce types, spinach), culinary herbs (e.g., basil, mint), and small vine crops or strawberries.
   
   The system offers significant resource efficiency:
   
3. Water Conservation: The system is recirculating, capturing and reusing nutrient solution, dramatically reducing water usage compared to conventional field agriculture.
   
4. Precision Dosing: Automation allows precise control over environmental parameters (temperature, humidity) and chemical parameters (pH and Electrical Conductivity, or EC), ensuring optimal plant health and maximizing predictable yields.
   
5. Space Utilization: The vertical configuration enables maximum productivity per square meter of facility space, making it a sustainable choice for urban or land-constrained farming operations.
