The nutrient solution seeps through the container and may or may not be recycled when it reaches the bottom. Return to Table of Contents Summary Several developments in the past few years have made hydroponic gardening easier for the home gardener. Newer systems are simpler to set up and operate. An increase in suppliers of hydroponic products means equipment and special fertilizers are more easily obtained by the home gardener. The use of lightweight plastics in the newer systems makes hydroponics less expensive and a better investment than older systems that used heavy, concrete benches.
Hydroponic systems are available in a variety of sizes and prices.
Kits are available from many suppliers, and some hydroponic systems can be built easily at home from materials found at hardware stores and fish supply stores. Numerous hydroponic and soilless gardening books can be found in local libraries and bookstores. A quick fix for most of the deficiencies is to spray the leaves with an all-purpose, foliar fertilizer, although this will not completely solve the problem. The best remedy is to change the nutrient solution every week instead of every two weeks. In some cases, it may be necessary to switch to a different type of hydroponic fertilizer, if the same deficiencies persist.
