BY ROOTLESS FARM
// TL;DR — VERDICT
DWC is the better hobby system; NFT is the better small-commercial system.
| Feature | DWC | NFT |
|---|---|---|
| Cost (10 plants) | $50–80 | $150–250 |
| Difficulty | 1/5 | 2/5 |
| Pump failure buffer | 24 hours | 15 minutes |
| Water use | High | Low |
| Crops | Lettuce, herbs, tomato | Lettuce, herbs (not heavy fruit) |
| Scales vertically | No | Yes |
// CHOOSE
DWC IF…
- — You are new to hydroponics
- — You grow at home for personal use
- — Power outages are a concern
// CHOOSE
NFT IF…
- — You are running a small commercial operation
- — Water is expensive or scarce
- — You need vertical stacking for footprint
When to switch
Most growers start with DWC, learn pH/EC management, then graduate to NFT for the next build. The skills transfer cleanly.
FAQ
2 entries- Q01Is DWC or NFT better for lettuce?
- Both work. DWC is more forgiving of pump failure (24h buffer of solution); NFT uses 60% less water and stacks vertically more easily.
- Q02Which is cheaper to build?
- DWC, by 40–60%. A 4-plant DWC tote costs $50–80; a 10-plant NFT channel costs $150–250 in parts.
