Hydroponic gardening is a great way to get the most out of your plants. These plants can save you money over the long term. Hydroponically grown plants are highly dependent on the use of the correct nutrients at the right times and the proper pH balance. You can endanger your plants if you do not use the right nutrients.

You can make your own nutrient solution or purchase hydroponic nutrients at http://nuviatec.com/ which is already prepared. The solution must contain all the necessary macro and micro elements for plant growth. The water solution should contain the most macro elements, such as potassium, phosphorus, and nitrogen. 

The development of leaves, stems and cell growth is dependent on nitrogen. Phosphorus plays a vital role in bud development, the creation of fruits and flowers, and helps to grow healthy roots. Plant cells use potassium to absorb energy during photosynthesis.

Magnesium, sulphur and calcium are also important macro elements. Elements such as carbon, oxygen, and hydrogen can be obtained from air and water. Copper, iron, zinc and manganese are some of the microelements or trace elements, that can be found in lower amounts.

These macros and microelements should be included in any homemade or prepared solution. You can make your own fertilizers using salts like potassium sulphate/Epsom, magnesium sulphate/magnesium nitrates, calcium sulphate and sodium nitrate. These fertilizers are available at large plant nurseries as well as plant shops.
