Over the years hydroponics has grown popular and for good reason. It has been proven to yield better quality plants while minimizing water usage. It uses advanced techniques which can be learned and mastered by almost any experienced gardener. It is convenient as hydroponics allow garden setups to be started almost anywhere as long as certain requirements are met. It also uses light weight materials such as plastic containers which make start up costs relatively cheap. Prior to gardening, do some research about the plant you are growing, and consider hydroponic gardening.

The nutrient concentration of a hydroponic garden is often referred to as the EC level. If your hydroponic garden consists of Grodan plants, they would require less fertilizer then what they would need in a soil based garden. This is because of the technical system of hydroponic gardens. In soil gardens the nutrients in fertilizers are not all absorbed by the plants, because the soil acts like a buffer. In a hydroponic set up, there is nothing acting as a buffer, and all the nutrients from fertilizers are easily absorbed by the plants. It is a general rule that EC and pH should never be lower then 5 and higher then 7, as the plant would not be able to absorb any nutrients.

Before introducing a plant in the previous diseased area, clean up any residue left behind. Diseased Plants should be removed and its area should be cleaned thoroughly with a bleach solution. Before changing any water in the tank, wash it out with a cleaning solution. Remove any residue, and make sure areas which hosted a diseased plant are cleaned properly.
