Nutriculture NFT Grow Systems (Larger Sizes)

Nutriculture NFT Grow Systems (Larger Sizes) — Space-Efficient Hydroponics for Real Yields

Best for: Growers scaling up from smaller systems, or anyone with limited headroom who wants 3x the yield without the footprint

The Nutriculture NFT (Nutrient Film Technique) Grow System is a complete, ready-to-run hydroponic kit that grows plants without soil or pots. Instead, a thin film of nutrient solution constantly flows down a specially designed tray, and plant roots sit in rockwool cubes getting fed 24/7. The result? Faster growth, compact root development, and up to 3x bigger yields than potted growing. All in a low-profile footprint that fits spaces where conventional lighting won't.

How it compares

NFT is different from other hydroponic methods — here's why that matters:

• vs. DWC: Uses significantly less water and nutrients. More vulnerable to pump failure, but far more water-efficient and disease-resistant
• vs. Drip systems: No pots, no medium waste, simpler cleanup. Less flexible for very large plants
• vs. Soil/Coco: Constant nutrient availability means faster growth, better yields, zero buffer between root and feed — you're in full control

NFT thrives with leafy greens, herbs, and plants with lighter nutrient demands. It's space-smart and resource-efficient.

Usage guidance

System setup
The kit comes complete — reservoir, tray, spreader matting, pump, and delivery pipes. The pump runs 24/7 non-stop. No timer needed, no segmented feeding schedule. Nutrient solution is continuously pumped from the reservoir, flows down the angled tray as a thin film, and returns to the tank in a closed loop.

Planting and propagation
Start cuttings or seedlings in small rockwool cubes. Once roots are healthy and white, transplant into 3-, 4-, or 6-inch cubes and place on the system through pre-cut holes in the Correx cover. Rule of thumb: 1 plant per square foot, though you can adjust based on variety.

Nutrient management
NFT requires lower fertiliser doses than other hydro methods because there's no buffer between root and solution. Start at half the manufacturer's recommended dose and gradually increase to full strength over the growing cycle.

Critical maintenance
The pump must run continuously. If it stops, plants suffer quickly. Keep a spare pump handy — this isn't optional.

Plant support
Fast growth means plants often need staking or support netting as they develop.

Technical specifications

• GT604 model: 153cm (L) x 50cm (W) x 20cm (H) | 60 litre capacity
• GT901 model: 212cm (L) x 53cm (W) x 20cm (H) | 80 litre capacity
• Growing medium: 100% rockwool cubes (no soil or coco)
• System operation: Continuous pump circulation, 24/7, no timer required
• Cover: Correx sheeting (prevents algal growth, protects roots)
• Nutrient delivery: Thin-film recirculation with spreader matting for even distribution
• Key advantage: Ultra-low water usage, high oxygen availability at root zone

Who this is for

• Hobby growers stepping up from smaller systems or soil growing
• Growers with space constraints — lofts, grow tents, limited headroom environments
• Anyone prioritising yields and speed over crop variety
• Growers running fast-turnover crops (leafy greens, herbs, microgreens)
• Water and nutrient efficiency matters to you
• You're comfortable with a system that requires vigilant pump maintenance

Our take

NFT systems get a reputation for being fiddly. They're not — they're actually very straightforward if you understand what they are: a constantly flowing nutrient delivery system. The Nutriculture Gro-Tank is the UK's best-selling NFT kit for good reason. It's proven, well-built, and does exactly what it should.

Pick the GT604 if you're working with moderate space; go GT901 if you need more channel length and capacity. Either way, you're getting a system that delivers proper yields from a tight footprint, backed by 30+ years of real-world performance. Worth picking up while stock lasts.
