There is a large variety in retail stores that offer Hydroponic nutrients. Examples of these are Hydroempire, Hydroasis, Igrowhydro, Hydroponics and Xnutrients.
One hydroponic nutrient in a plant is water. Water is an essential nutrient for all life. Another hydroponic nutrient in plants is magnesium sulphate.
One could do a little research on a home and garden website first to learn about the advantages of a hydroponic grow system. After research, one would probably find that Instructables would be a good site to find and purchase such a system.
Hydroponic supplies can be purchased through many other retailers. This includes BG Hydro, HTG Supply, Hydroponic Wholesale and Amazon. The products are different in each site.
One purchase hydroponic lights at any local garden or plant store. These types of lights can also be found at large department stores such as Walmart.

Hi there yes you can If you want to you should look up universal indicator paper or liquid litmus paper is a version on line you should find a home made one and a chart to tell you if you're soil is alkali or acidic the scale has these at either end and you want a match in the middle.
Authorities say healthy plants have access to 16-18 nutrients. Regular feedings are of the three major nutrients: nitrogen, phosphorus, potassium. Other nutrients are needed in smaller amounts. Examples are boron, calcium, cobalt, copper, iron, magnesium, manganese, molybdenum, sulfur, and zinc. Even though they are in small amounts, they are important. A scientist of the 19th century, Count Liebig, found that if any one nutrient is not present in the correct amount be it small or large, then the entire feeding is thrown off. Hydroponic feedings are of the three, and of all the others. They also are more water soluble. Plants need good water solubility. Otherwise, they cannot take in any nutrients no matter how available the latter may be. For hydroponic feedings constantly check the pH. Is the pH acidic, neutral, or alkaline? An incorrect pH can make an available nutrient unavailable to the plant. With this we need to see that different different plants need different nutrients combination for their growth. But in my opinion if we are not aware of all the ingredients which are used in particular nutrient for particular plant then some times we are missing the massive yields which we should get.
A large number of websites offer advice on hydroponic gardening but the one which offers the most extensive help is "somhydro". This website covers almost all aspects of the subject.

One would shop for a used Vauxhall Meriva from Exchange and Mart. One could also shop for a used Vauxhall Meriva from Calibex, Autotrader, Motors, and Amazon.
In the soil nutrients bond to soil/ colloidal particles; in hydroponics there is no soil only a volume of liquid. As the medium is liquid the individual chemical elements are more or less free to move and are exposed to other elements are a much greater rate than what they would be in the soil. This results in chemical bonding, some of the new products formed are insoluble in water (unless the pH and temperature are manipulated); these are normally heavier and precipitate to the bottom of the mixing/ storage tanks. For this reason some nutrients are only added to the solution just prior to use so that they do not precipitate out (Iron/ Fe being one of them).
