(2015) found higher phenolic acid levels in lettuce plants in non-aerated nutrient solutions than in lettuce from aerated nutrient solutions. Considering that comparable higher phenolic acid concentrations in lettuce from hemp and Wooden had been measured in our experiments, nevertheless the significant oxygen deficiency only transpired in hemp, the availability of nitrogen would seem to have a greater impact on phenolic acid concentrations.
