Nominal EC Values for Hydroponic Crops

By: Bluelab  05-Apr-2012

Below is a list of crops with the ideal EC value the crop is grown at in a hydroponic system for optimum performance.

Although there are ideal EC values for each plant type, this does not mean that a range of plants, all technically requiring different strength nutrients, cannot be grown in a home situation together.

The grower simply lists the range of EC values and picks an average value. For most home systems this value is between 1.2EC and 2.0EC depending upon the requirements of the predominant crop types being grown.

Brief History of Hydroponics

Liebig, a German scientist, started using nutrient solutions to study the nutritional requirements of plants in the 1850's and was followed by Sachs in 1860 and Knop in 1861 who made studies of nutrient elements in water solutions. The term hydroponics was coined in the USA in the early 1930's to describe the growing of plants with their roots suspended in water containing mineral nutrients.

Starting out with Hydroponics

The NFT system development by Dr Alan Cooper involves a system of covered plastic channels, the plants growing through holes in the covers with their roots in the nutrient solution. Hydroponic gardening can alter your lifestyle by providing you with fresh fruit, vegetables and flowers all year round. You will be able to grow a large number of plants in a small area producing a far higher yield than normally possible.
