Thesis (MTech (Horticultural Science))--Cape Peninsula University of Technology, 2016. / This aim of this study was to investigate the viability of growing P. tomentosum in deep water culture (DWC) hydroponics and to assess the effects of various methods of oxygenating the nutrient solution with regards to growth, development and chlorophyll responses. The experiment was conducted over a period of 74 days. In chapter 3, 16 different methods of oxygenation were applied to 9 replicates. The control had passive aeration. The treatments were made up of air-pumps, vortex oxygenators and the application of hydrogen peroxide (H2O2) at various frequency intervals; these were combined with each other and run as separate oxygenation methods.
