DWC vs NFT vs Aeroponics: Which System Should You Build?
A field-tested comparison of the three most popular hydroponic methods — by yield, cost, complexity, and crop fit.
The three systems at a glance
Deep Water Culture (DWC) suspends roots in oxygenated nutrient solution. Nutrient Film Technique (NFT) recirculates a thin film of solution through sloped channels. Aeroponics mists roots in open air. Each trades cost, resilience, and yield differently.
Cost & complexity
DWC is the cheapest and most forgiving — a tote, an air pump, and a stone. NFT requires precise slope and a reliable pump but uses very little water. Aeroponics demands the highest equipment investment and the lowest tolerance for failure: a 30-minute pump outage can kill a crop.
Best crop fit
Lettuce, basil and most leafy greens thrive in NFT. Tomatoes, peppers and cucumbers prefer the buffering capacity of DWC. Aeroponics shines for fast cloning, herbs, and research-grade tomato breeding.
Our verdict
If this is your first build, start with DWC. Move to NFT once you can hold pH within ±0.2 for a full week. Only attempt aeroponics with battery-backed pumps and a redundant misting line.
