Fertigation Recipes

The fertigation system Hydria 4+ Touch can store and execute up to six fertigation recipes, whereas recipe No 0 is preset to irrigation with fresh water.

In each fertigation recipe, the following can be set: the desired electrical conductivity (EC) and acidity (pH) values, the nutrient solution ratios and whether the EC will be adjusted in an absolute or differential manner.
For the use of differential EC, an input EC meter is required, which can be offered as optional component in Hydria 4+ Touch.
