To many in the agricultural set, the essence of growing the best fruit, vegetables, and flowers is perfect soil that is rich in nutrients and well aerated. But a better way might be no soil at all. Hydroponics, feeding plants via a flow of water filled with nitrogen, phosphorous, potassium, and a number of trace minerals, is well established in Europe and Asia. The cultivation technique even works indoors with high-intensity lights that replicate the sun's rays. All of the lights, trays, fertilizers, supplements, testing equipment, growing mediums, irrigation systems, and information you need can be found at Gold Coast's two stores. The service is professional and subdued. The stores are clean and well organized. The only negative is that the prices are a bit, um, pricey. But note that commercially grown tomatoes go for about a dollar per pound. Hydroponically grown tomatoes (blemish-free and consistent in taste, texture, size, and shape) go for triple that. A sample system set up in the window of the Bird Road outlet boasts bushy growth, brightening the dreary stripmall where it is located. Indeed considering the proliferation of stripmalls, freeways, sidewalks, and basketball courts, soilless gardening may someday be the only method available.
