Hydroponic Tower with 36 Plants in 4 Tubes : Soilless Indoor Cultivation
This NFT (Nutrient Film Technique) hydroponic growing tower features a compact structure with 4 food-grade PVC tubes, each drilled with 36 planting sites, a submersible pump, and all the baskets and germination sponges needed for an immediate start. You get a self-contained vertical growing system without substrate, designed for salads, strawberries, herbs, and leafy greens indoors, on a balcony, or in a greenhouse.
🌿 How it Works and Design
The NFT principle involves circulating a thin film of nutrient solution in a loop over bare roots, through inclined tubes. The submersible pump draws water from the reservoir (to be provided : a basin or aquarium-type container), propels it to the top of the tower, then the water naturally flows down by gravity from one tube to another before returning to the reservoir.
The structure is assembled without glue, using watertight interlocking fittings, which facilitates disassembly for seasonal cleaning. The wide-mesh planting baskets (32 mm) accommodate the provided germination sponges, in which seeds germinate and then develop their roots directly in the nutrient flow.
⚡ Features and Performance
Tubes made of food-grade PVC-U (drinking water quality), UV-resistant for greenhouse or conservatory use. Planting hole diameter 32 mm, compatible with standard hydroponic industry planting baskets.
Submersible pump 220 V / 50 Hz specially adapted for aquaponic tanks, capable of continuous operation without overheating.
Small footprint (95 × 45 cm) for a height of 100 cm, allowing installation behind a bay window, on a covered balcony, or in a garage corner with a grow light. Water consumption is approximately 10 times lower than a traditional in-ground vegetable garden.
🥬 Recommended Uses
Production of fresh salads in short cycles (3 to 4 weeks from seed to harvest). Productive year-round cultivation of herbs (basil, parsley, chives, mint). Strawberries in season on the upper rows for a clean, slug-free harvest.
Adaptable to aquaponics by coupling the system with a freshwater pond or aquarium.

🤓 Practical Tips
Installation : provide a reservoir of at least 30 L under the structure (basin, aquarium, or gardening tub type). Assemble the tubes by interlocking, immerse the pump in the reservoir, connect the supply hoses, and check for circulation without plants for 1 hour.
Starting cultivation : germinate seeds in sponges (5-7 days in gentle heat), then transfer each sponge into a basket as soon as the first two true leaves appear. Add hydroponic fertilizer to the reservoir according to the manufacturer's recommended dose if you are not using an aquaponic system.
Mistakes to avoid : never let the pump run dry (risk of burning out), do not overload a single tube (roots can block the flow), do not use classic garden fertilizer (too saline for hydroponics).
Maintenance : clean the tubes with diluted white vinegar every 2-3 months to prevent biofilm. Replace the nutrient solution every 2 to 3 weeks. Winterize the pump in a bucket of water if the tower is left unused for a long time.
🛒 Why Choose This Hydroponic System
You get a complete hydroponic kit delivered ready to assemble, with pump and accessories included, in a compact size suitable for a balcony or office. Food-grade PVC and glueless assembly ensure a healthy and durable system, detachable for cleaning.
The 36 planting sites spread over 4 levels maximize production in 0.4 m² of floor space, making it one of the best surface/yield ratios for domestic hydroponics. NFT technology is proven, water-efficient, and suitable for both beginners and aquaponics enthusiasts.
