Optimum pH for Artemisia Annua
Answered by: Conrad Richter

Just a quick question, I am growing this plant hydroponically and in rockwool cubes, and need to know what pH the rockwool cubes should be at?

We are not aware of any studies to determine the optimal pH for Artemisia annua. My guess is that a pH between 6.0 and 7.0 should be okay. Certainly, it seems to grow well in soils in that pH range.
