Document Summary
What is the definition of hydroponics: science of growing plants without soil (e. g. rockwool, coconut fiber, pebbles, and any other media with a low mineral base content) What are some advantages of hydroponics: allows grower to have near complete control over nutrient intake increased yields, efficient production, clean overall production. What are some drawbacks of hydroponics: expensive and complex set-up, requires time and technical knowledge, continual monitoring needed, not as forgiving as soil production. What are the three minimum equipment requirements: water monitor, quality water source, measuring equipment. Where does ph rank on the order of concern? ph is the number one concern with any operation, hydroponics especially. Why can ph change quickly in hydroponic systems: lack of buffering factors quick changes in ph. Passive hydroponic systems rely on capillary action through a wick system. Active hydroponic system typically incorporate the use of a recirculation to move water.
