Rapid Efficient Compact Fresh

Sainpoly's NFT Hydroponic Greenhouse System for Indoor Lettuce reflects the brand's commitment to sustainable urban farming, engineered with precision manufacturing and food-safe materials to deliver consistent, high-yield lettuce growth in compact spaces. The system uses the nutrient film technique with automated water circulation, adjustable LED spectrum lighting, modular tray design, and easy-to-clean components to simplify seeding, monitoring, and harvest while minimizing water and space use. Combining energy-efficient operation, scalability from hobbyists to commercial growers, and reliable crop uniformity, this product ranks among Top sale products for those seeking a turnkey indoor lettuce solution that cuts costs and shortens time-to-harvest.

Material introduction

The Sainpoly NFT hydroponic greenhouse relies on food-grade plastics—PVC, PE, and PP—for its planting and return pipes (planting Ø75 mm, inlet Ø25 mm, planting cup Ø32 mm) and joint fittings, ensuring inert contact with nutrient solutions. Load-bearing frames and welded supports use stainless steel or hot-galvanized steel with taper rings, elbows, tees, valves, and pressure compensators to provide corrosion resistance and long service life in humid indoor lettuce cultivation. These carefully chosen materials deliver hygienic, low-maintenance operation and high yields, which help make this customizable system one of our Top sale products.

FAQ

What is the Sainpoly NFT Hydroponic Greenhouse System designed for?

The system is built to grow leafy greens—especially indoor lettuce—using nutrient film technique (NFT) channels inside a controlled greenhouse/rack. It provides a continuous thin film of nutrient solution over roots, enabling fast, clean, space-efficient production for restaurants, retailers, schools, research, urban farms and home growers.

In which application scenarios does this system work best?

It fits indoor and semi-indoor environments where consistent, year‑round lettuce production is needed: countertop or back‑of‑house kitchens and restaurants for hyper‑fresh supply; supermarket micro‑farms and display grow walls; vertical/stacked urban farms; classrooms and demonstration farms for education; and R&D or seedling labs. It’s scalable from a single home rack to multi‑tier commercial setups.

How many plants can I grow and what is the typical production cycle?

Capacity depends on the chosen module size and tiering. Plant spacing for lettuce usually ranges from about 12–20 cm (5–8 in) between plants depending on variety. Lettuce grown in NFT typically reaches harvest in about 30–45 days (leaf varieties can be faster). With staggered planting you can achieve continuous harvests—plant a new row weekly or biweekly to maintain steady supply.

What environmental and nutrient settings should I use for optimal lettuce growth?

Recommended ranges for lettuce: pH 5.5–6.5, electrical conductivity (EC) about 1.2–1.8 mS/cm (adjust by variety and growth stage), water temperature 18–22 °C (64–72 °F). Provide LED grow lighting with PPFD roughly 150–250 μmol/m²/s and a photoperiod of 14–16 hours for most lettuce types. Ensure good air circulation and maintain relative humidity around 50–70%.

What routine maintenance is required and how often should I do it?

Daily: check pumps, water level, and plant health; top up reservoir with water/nutrient solution as needed. Every 3–7 days: measure and adjust pH and EC. Every 1–2 weeks: refresh nutrient solution (partial or full change depending on monitoring). Monthly: clean filters, inspect and clean channels to prevent sediment and root clogging. Seasonally or between crop cycles: sanitize channels and reservoir to control pathogens and algae. Keep spare pumps and basic tools on hand.

What are common problems and quick troubleshooting tips?

Root rot/poor oxygenation – raise dissolved oxygen by lowering water temp, increasing flow rate or adding aeration; avoid stagnant solution. Algae growth – cover channels and reservoir to block light, clean regularly. pH or EC drift – adjust quickly using calibrated solutions and consider automation for frequent dosing. Uneven growth – check light uniformity, nutrient distribution, and pump/flow blockages. Pump failure – use timer/sensor alarms and redundant pumps for critical setups. If you see pests or disease, isolate affected plants and sanitize equipment; integrate IPM practices for prevention.
