PH and Conductivity are the two most important variables in nutrient solution management. A basic understanding of them is essential for successful hydroponics gardening. PH is a measurement of the acidity or alkalinity of a solution.
On a scale of 1-14 neutrality is represented as 7. The ideal pH for almost all hydroponics applications is 6. PH for rockwool cultivation should be slightly lower, ideally about 5.8.
