Commercial PVC NFT Hydroponic System for Greenhouses

The Skyplant Commercial PVC NFT Hydroponic System is a soil-free growing setup designed for commercial greenhouse or urban farm use. It uses the Nutrient Film Technique (NFT) to recirculate a thin film of nutrient solution across plant roots in food-grade, UV-resistant PVC channels for efficient, high-density vegetable and fruit production year-round.

Models shown are SP-H-200, SP-H-400 and SP-H-800. The SP-H-400 corresponds to the 4.0 m length example in the description (4.0 m × 1.5 m × 1.0 m). Other models are proportionally shorter/longer (200 cm and 800 cm); contact the supplier for exact dimensions and configuration per model.

The listing states that each 4 m section (SP-H-400) is equipped with 25 planting holes. Hole counts for other model lengths may scale accordingly—confirm the exact number of holes for SP-H-200 and SP-H-800 with the vendor.

The system is constructed from food-grade, UV-resistant PVC designed for durability and long service life. The materials are selected to be safe for growing edible crops; verify specific material certifications with your supplier if required.

It uses the Nutrient Film Technique (NFT), where a thin recirculating stream of nutrient solution flows along the bottom of the channels, bathing roots and promoting rapid nutrient uptake and oxygenation without soil.

Package contents vary by vendor. The core product is the PVC NFT channel system; pumps, reservoirs, fittings, nutrient dosing, lighting and automation may be sold separately or included in kit options. Confirm included components with the seller or request a full kit if you need a turnkey solution.

This NFT system is ideal for leafy greens (lettuce, spinach, kale), herbs, and smaller fruiting crops like strawberries and some determinate tomatoes or peppers. Larger vine crops may require support and spacing adjustments. Choose varieties suited to high-density hydroponic production.

Optimal conditions depend on the crop, but generally: full greenhouse or supplemental grow lighting for year-round production; temperatures typically 18–26°C for most leafy greens; relative humidity 50–75%. Fruiting crops may require warmer day temperatures and higher light levels. Monitor crop-specific requirements.

Maintain nutrient solution pH in crop-appropriate ranges—commonly 5.5–6.5 for most greens. Electrical conductivity (EC) varies by crop: leafy greens ~1.0–1.6 mS/cm, herbs ~1.0–2.0 mS/cm, fruiting crops higher (2.0–3.5 mS/cm). Check and top up nutrient solution daily and perform a full reservoir change or balancing schedule per your nutrient supplier's recommendations.

Regular maintenance includes daily monitoring of pump operation and solution levels, weekly checks of pH/EC, and periodic flushing/cleaning of channels and reservoir (typically every 2–8 weeks depending on crop and water quality). Clean channels between crop cycles with food-safe disinfectant to prevent biofilm and pathogen buildup.

Allow space for the system footprint (check model dimensions), access aisles for planting and harvest, and room for a reservoir and pump. Ensure a level floor, appropriate drainage and potable water access. Installation can be modular and scalable—multiple units can be linked or arranged to fit greenhouse layouts.

NFT systems typically use substantially less water than field soil production because water is recirculated; savings commonly range from 70–90% depending on management. Labour is reduced for tasks like weeding and soil preparation, but you still need labour for planting, monitoring, pruning and harvest.

Use integrated pest management (IPM): maintain good hygiene, clean channels between crops, monitor plants frequently, control greenhouse ingress, and introduce biological controls or targeted treatments when needed. Proper nutrient balance and environmental control reduce plant stress and disease susceptibility.

Warranty, technical support and spare-parts availability vary by supplier and region. Ask the vendor for warranty terms, lead times for replacement parts (pipe fittings, net pots, pumps) and available installation or after-sales service before purchasing.

Yes. NFT systems are commonly integrated with timers, nutrient dosing systems, pH/EC controllers, flow sensors and environmental monitoring (temperature, humidity, CO2, light). Check compatibility with your chosen automation components or ask the supplier for recommended controllers and integration options.
