1. This presentation talks about Hydroponics, an interesting method of cultivating plants without using soil. The starts by giving a description of Hydroponics, usage and ends on discussing the advantages and disadvantages of using the Hydroponics way of growing plants.

2. Today I am going to give you the information you need to know about hydroponics. For those who don’t know what hydroponics is, it is simply a plant that is grown without soil and it grows in water with a rock called Prelate to anchor the roots. I will discuss: General Hydroponics, Hydroponic System, Hydroponic Growing, Hydroponic Lights and Homemade hydroponics

4. Growing medium is the material in which the roots of the plant are growing The growing medium is an inert substance that doesn't supply any nutrition to the plants. All the nutrition comes from the nutrient solution (water and fertilizer combined). You can therefore, easily control everything the plants receive. The strength and pH of the nutrient solution is easy to adjust so that the plants receive just the right amount of food.

5. Definitely one of the most important components of any artificial gardening system is the lighting. Hydroponic lights come in various sizes, intensities and purposes. The light your plants get will affect the way they grow, how fast they grow and the quality of the crops, so getting the right hydroponic lightning system is crucial, regardless of what you’re growing. The type of color (red or blue nuances) that your lighting system emits is also a decisive factor in the growth of your plants. For many of us, DIY stuff is a little slice of heaven. There’s no comparing to the feeling of building something with your own hands, then seeing your baby work properly. Home made Hydroponic Systems not only offer this joy, but they’ll also save you some serious pocket money. Basic advantage is that you don't have to worry about choice of soil as no soil is used. The absence of soil eliminates all the soil related problems. Using homemade hydroponic systems, one can have vegetation where natural soil does not support it or is not conducive to its growth.
