Hydroponics is the technique of growing plants without soil. It works on the principle that plant growth can be optimized by controlling the conditions of growth. Towards this end, different hydroponic growing systems have evolved to suit different growing requirements. The choice of an appropriate hydroponic growing system depends on the type of plants, the scale of the growing unit, and the expense and time that the grower is ready to invest. Described below are some hydroponic growing systems:

Wick system. This is the most basic hydroponic growing system. It makes use of an absorbent ‘wick’ such as a nylon rope suspended between the growing medium of the plants and a reservoir of nutrient solution. The wick draws in nutrients based on how soon the plants absorb it. A suitably absorbent medium is needed for this system such as a combination of perlite with either vermiculite or coconut coir. This system can be built using simple materials at home and is ideal for hobby growers having few plants. (more…)

Hydroponics uses several different types of lights for optimum plant growth. While using different grow lights, it is important to invest in a specialized digital ballast, which is a necessary component of any lighting circuit. Simply put, a ballast is an electronic component in a lighting system that controls the amount of current in a circuit. Without it, a grow light would fail to work.

Why Digital Ballasts
Earlier ballasts consisted of resistors, which is an inefficient way to control current, as it leads to loss of electricity. Modern digital ballasts limit current flow without wasting electricity. They also help to extend the lifespan of grow lights. Moreover, they help to reduce flickering, a common feature in older ballasts. Also, the performance of most conventional magnetic ballasts worsens after few years of operation, while digital ballasts provide a consistent lumen output and efficiency over its lifetime. As a bonus, digital ballasts offer noise-free operation and less startup time, or the time required to achieve full brightness. (more…)
