In 2008, I experimented with growing food using the hydroponic method. I grew cucumbers, Romain lettuce, and cantaloupes. The plants grew very well. The lettuce in particular exhibited better long term storage properties than conventionally grown lettuce but this may have been due to confounding factors. For example, it's a fact that almost all lettuce (~90%) consumed in the USA is grown in just three to four counties in the American Southwest (CA and AZ). Hence, the short storage life and rapid wilting many people experience with the lettuce they purchase in grocery stores may actually be a result of the lettuce spending most of its post-harvest life in trucks in transit to retail locations.
