Peer-reviewed studies and reference materials demonstrate that various plants can be successfully cultivated indoors using artificial light sources such as LEDs.
A growing population generates tremendous demand for food, especially of vegetables, in space limited cities such as Singapore. Rooftop and vertical farms integrated with various technologies, such as hydroponics and aquaponics, have been commercialized over the past few years in Singapore. However, to compensate for the lack of land space and an increasing population, Singapore needs to develop its own unique effective farming system that will be independent of eventual climate changes. Using aeroponic systems, our previous studies showed that cooling the root-zone (RZ) could produce all types of vegetables throughout the year. Currently, we have expanded Singapore's urban farming technology by successfully developing an LED-integrated vertical aeroponic farming (VAF) system that can be used both indoors and in greenhouses, for vegetable production. Other than providing sufficient and uniform light intensity to the plants, the factor key to the success of this VAF system is the provision of a low energy input engineering solution - the use of light emitting diodes (LEDs) - to enhance photosynthesis and maximise crop productivity. Our self-designed LED integrated VAF systems have been used to successfully grow lettuce (Lactuca sativa), Chinese broccoli (Brassica alboglabra), Nai Bai (Brassica chinensis), mizuna (Brassica juncea var. japonica) and culinary herbs, such as red and green Chinese basil (Perilla frutescens), and sweet basil (Ocimum basilicum).

The facultative halophyte Mesembryanthemum crystallinum (ice plant) has high nutritional values. In Singapore, we have successfully grown M. crystallinum indoors under different LED-lightings using freshwater. Since halophytes are capable of tolerating a wide range of salinities, it provides a basis for cultivating them as vegetables using saline water. This study aimed to investigate the impacts of different NaCl concentrations on productivity and photosynthesis of M. crystallinum . All plants were grown under different salinities by adding 0, 100, 250 and 500 mM NaCl, respectively, to a full strength Netherlands Standard Composition. Photosynthetic photo flux density at 156 μmol m ‑2 s ‑1 (12 h photoperiod) was provided to all plants by LED with red:blue ratio of 2.2. Twenty days after transplanting, plants grown under 100 mM NaCl had the highest shoot fresh weight and largest total leaf area followed by plants grown at 0, 250 and 500 mM NaCl. Plants grown under 500 mM NaCl had the lowest specific leaf area due to its highest leaf dry matter content and lowest water content. However, all plants had similar values of leaf succulence (g FW cm ‑2 ). Although all plants had chlorophyll fluorescence Fv/Fm ratios >0.8, photochemical quenching and electron transport rate were significantly higher in plants grown under 0 mM NaCl than under 100, 250 and 500 mM NaCl measured under the growth irradiance. CAM acidity of plants grown at 500 mM NaCl was induced while CAM acidity of plant
