VIVOSUN 3-Layer Hydroponic Growing System 108 Sites — NFT PVC-U Pipes, Pump with Timer for Leafy Greens

VIVOSUN's 3-layer hydroponic growing system is a complete NFT-style kit that grows up to 108 leafy plants indoors or outdoors using timed nutrient circulation.

This ready-to-assemble kit combines food-grade PVC-U pipes, a circulation pump with timer, nest baskets and sponges to create a compact, soilless growing environment optimized for lettuce, herbs and other leafy vegetables. The system uses a nutrient film technique (NFT) to deliver water and nutrients efficiently, reducing water use and footprint compared with traditional soil beds. Included accessories and a timer make it beginner-friendly, while the three-tier layout multiplies planting capacity on a small footprint.

How does the timer and pump keep nutrients consistent?

The included timer cycles the pump to create a thin, continuous film of nutrient solution across the pipe channels without flooding the roots. The default schedule runs the pump 5 minutes every 30 minutes, but you can switch to manual or customize intervals for specific crops. Regular, brief circulation keeps oxygen available to roots and reduces nutrient waste.

• Default automatic cycle: 5 minutes on, 25 minutes off.
• Manual or custom timing options to suit different plants.
• Pump placement and tubing minimize pooling and ensure flow across all rows.

What plants grow best in this 108-site system?

This NFT-style kit excels with fast-growing, shallow-rooted vegetables and herbs such as lettuce, spinach, bok choy and basil. Root-loving vegetables with deeper systems (like full-size tomatoes) are less ideal unless given additional support. The three-tier design lets you dedicate rows to different crops or stagger planting schedules for continuous harvests.

• Best: leafy greens, microgreens, herbs, pak choi.
• Possible with support: small peppers and seedlings.
• Avoid: large, deep-rooted plants without modification.

How simple is assembly and everyday maintenance?

The kit is built for straightforward setup and routine care: pipes snap together, baskets and sponges seat into pre-cut holes, and the pump connects with supplied tubing and the timer. Filling the reservoir, mixing nutrients, and following the timer keep the system running; periodic cleaning and nutrient top-offs are the main maintenance tasks. Clear instructions and included tools help first-time growers get started quickly.

• Assembly: tool-friendly parts and illustrated instructions included.
• Daily/weekly care: check water level, top-off nutrients, inspect pump.
• Quarterly: flush pipes and clean pump to prevent buildup.

How does this system save space and resources compared to soil gardening?

By circulating nutrient solution directly to roots in narrow channels, NFT systems use far less water and surface area than traditional beds while maintaining fast growth. The vertical-aware, three-layer layout quadruples planting density relative to a single-row trough, making it suitable for balconies, garages, patios or small backyards. Reduced substrate needs and targeted feeding also lower ongoing material costs.

• Efficient water use: recirculating reservoir reduces waste.
• High yield per square foot via compact, stacked layout.
• Minimal growing media required — just nest baskets and sponges.

Who is this for: This VIVOSUN hydroponic grow kit is ideal for home gardeners, urban growers and beginners who want to produce a large volume of leafy greens in a compact space without soil. It also suits hobbyists who want to scale up from single pots to a continuous, multi-tiered production line with controllable irrigation. If you need low-footprint, higher-yield gardening with manageable upkeep, this system provides an accessible, hardware-complete solution.
