Hydroponic Greenhouse Production Resources
Hydroponics is a production method where the plants are grown in a nutrient solution rather than in soil. The greenhouse and its environment control system are the same whether plants are grown conventionally or with hydroponics. The greenhouse needs to be suitable for production with adequate heat and ventilation and the ability to manage both, and clean glazing for maximum light. The difference between conventional production and growing hyroponically, is the support system for growing plants and the method of supplying water and nutrients.
Before investing in hydroponics, investigate hydroponic production. If possible, visit existing growers to see how systems are set up and research costs involved. Hydroponic systems have an increased initial investment added by the pumps, tanks, controls and support system. If supplemental lighting is included, a large additional cost will be incurred. Higher energy costs -pump and lighting operation increase the electricity costs. Also, more technical skill is needed. Begin small to learn about the various aspects of production.
Hydroponic systems can be built by adapting materials or by purchasing commercially available ready-made systems that provide everything you need, from instructional DVDs to the nutrient solution.
