Abstract
An outdoor year-round hydroponic demonstration garden has been maintained at the Seminole County Extension office in Sanford, FL, for the past six years. Hydroponic greenhouse trials and demonstrations were also conducted at the Seminole Community College Horticultural Unit the past four years. This describes the hydroponic systems that were tested, using locally available building materials, and discusses the successes and failures growing vegetables, herbs, and flowers. Although geared to the home gardener because of their simple, low cost design and maintenance, these systems have potential for use by small farmers, u-pick operations, and market gardeners.
