Hydroponics can be defined as a method for growing plants in water rather than soil. The main idea is that plants will grow in any media that contain all the nutrients of natural soil. Therefore, it’s these nutrients which are the most vital component in the hydroponics process. When using soil for plants, fertilizers contain only those essential nutrients which the soil may be lacking. Therefore, using a specifically formulated fertilizer made for hydroponic systems is required to benefit hydroponic plants.

Different plants need different proportions of nutrients for different times. Your better hydroponic nutrients are packaged in solutions labeled as ‘grow’ or ‘bloom’, that way even a novice grower can find these solutions without too much of a problem. As the growing cycle of your plants evolves make sure the nutrients evolve along with it. Another reason to change the solution is that the depletion of the elements is subject to the growth stage of the plant. At certain times, important elements get depleted faster. In an ideal word, the solution should be changed every two weeks. One must note that the proportion of nutrient solution and water must remain stable. If the fertilizer level increases due to evaporation of water, it could cause extensive root damage.

Usually the hydroponic nutrient solutions that are available are sold as a concentrate. Please follow the instructions to get the best results. Some plants will require a higher dosage than other plants. This dosage is indicated by species on the package. If you are unsure of the dosage consult your local nursery. For instance a weaker solution should be put for plants in poor growing conditions like overheated gardens, low lighting or just crowded plants. A weaker solution can aid even delicate newly planted cuttings. You will want to use a normal (regular) solution for any plant which is normal and healthy. You may be able to use a stronger solution if your garden has all of the requirements for high growth.  For example, do you have good air flow and good lighting such as natural sunlight or grow lights like LED grow lights? What about the production and circulation of carbon dioxide? But it’s advised to increase concentration of fertilizer slowly in order to keep the plant from getting burned up.

Though the concentrate to water ratio is in the range of 150 – 600 parts per million, the level for most of the plants is 300 – 400 ppm. Remember that this is not to be mixed with any part of a nutrient solution but with water.

Now that you are aware of the need for different nutrients, you need to know which ones to use.  It is most important to know which nutrient to look for. The first choice you have to make your growing medium you are going to use. For instance, if coco is the medium you are using, go in for specific nutrients like canna coco nutrients. In the crop stage, a vegetative nutrient formula is better suited for the vegetative stage of the plant such as Super Veg A or Super Veg B.

The nutrient required will depend upon the medium that is to be used. Nitrogen, potassium, and phosphorus are all elements that make up the organic or best hydroponic nutrients. Nitrogen is important for leaf vegetative growth. Potassium aides in cell production, while phosphorus helps to make roots grow.
