Not content to just give people the tools to make their gardens beautiful, San Diego Hydroponics & Organics also teaches customers more effective ways to use them. At five California locations, the staff works to keep a dialogue open between customers, supply manufacturers, and master gardeners while helping visitors realize their gardening goals with a stock of more than 3,000 products for indoor and outdoor use. The shops brim with high-tech gardening gear ranging from plant sprayers to growth lights, and low-tech supplies such as organic compost teas. Much of the inventory helps make gardening easier by reducing it to a precise science, providing everything from pumps and irrigation to pH meters for maintaining an ideal growing environment.
