2 pH and Conductivity

pH and Conductivity are the two most important variables in nutrient solution Managment. A basic understanding of them is essential for successful hydroponic gardening...

pH is a measurement of the acidity or alkkalinity of a solution. On a scale of 1 - 14 neutrality is represented as 7. The ideal pH for almost all hydroponic applications is 6. pH for Rockool cultivation should be slightly lower, ideally about 5.8.

Plants growing in soil have widely differing preferences for pH. This is not the case in hydroponics and all plants in hydroponic systems will function best at a nutrient pH of 6.
