New to Hydroponics and Growing? Check out these downloadable online brochures to get started...What is Hydroponics?A simple, to the point definition of hydroponics is: a way to grow plants using water and nutrients. Hydroponics is superior to growing in soil because you can give plants maximum levels of the exact nutrients they need. Precise control of nutrient uptake makes it possible to reap higher yields faster.
How does a plant work?Leaves are where photosynthesis—the process in which sunlight combines with CO2 and water and is then taken up by the roots to manufacture food (carbohydrates) for the plant—takes place and oxygen is released as a by-product. Plants regulate small openings, stomata, on leaf undersides to allow CO2 to enter and oxygen (O2) to exit. When open, stomata allow water vapor to escape in the process of transpiration. Roots anchor a plant in the ground and absorb water, nutrients, and air. Hydroponics allows absorption of water, nutrients, and air at an accelerated rate. Tiny root hairs increase the surface area of absorption. These root hairs are very delicate and must be moist at all times. Large roots are similar to stems. They transport water and dissolved minerals (fertilizer) in the phloem. Stems have a vascular system to transport water and nutrients throughout the plant. The xylem carries water and dissolved minerals from roots to leaves. The phloem transports food manufactured by leaves to the stems and roots. The vascular cambium is the growth zone that produces xylem on one side and phloem on the other. The stem also supports the plant and bears leaves, buds, flowers, and fruit. PLANTS FIVE BASIC NEEDS:
Where do I start?Once you've made the decision to grow hydroponically, you must decide where you want to garden: indoors, in a greenhouse, or outdoors. Next you must decide how to control the garden atmosphere.
