With proper management, a head of lettuce grown in ideal conditions in soil will grow as well as the same variety grown in a hydroponic system. [15] One advantage that DWC systems have over other forms of hydroponics is that plants may be re-spaced during the growth period, optimizing the growing area in regard to canopy cover and light-use. At ...
The method requires no substrate and entails growing plants with their roots suspended in a deep air or growth chamber with the roots periodically wetted with a fine mist of atomized nutrients. Excellent aeration is the main advantage of aeroponics. A diagram of the aeroponic technique
In spite of its high water content, traditionally grown lettuce has a low water footprint, with 237 liters (52 imp gal; 63 U.S. gal) of water required for each kilogram of lettuce produced. [35] Hydroponic growing methods can reduce this water consumption by nearly two orders of magnitude.
