Nutrient film technique (NFT) channels
What is a nutrient film technique (nft) channels?
NFT channels grow plants with roots in a thin, recirculating stream of nutrient solution running down sloped gutters. They suit lettuce, herbs and other short-cycle leafy crops, use little solution volume, and need uniform slope, clean channels and a backup pump plan.

Advantages
- Small circulating solution volume
- Channels are easy to clean
- High plant density for leafy crops
Limitations and risks
- Not suited to large, heavy, long-cycle crops
- Pump failure exposes roots quickly
- Root mats can block flow
Maintenance
- Clean channels between crops
- Check pumps and flow rates
- Monitor EC and pH daily
Sustainability and compliance
Recirculation limits discharge only when the solution is managed and treated.
Ask for food-contact material documentation for channels.
Questions to ask in your RFQ
- What slope and flow rate is the design based on?
- What happens if a pump fails?
- Are channels food-contact rated?
