Semi hardwood hydrangea cuttings propagation

Correction my indoor cuttings were not all hardwood cuttings. The thicker cuttings were semihardwood cuttings that I initially had in a jar of tap water in my kitchen(usually warmest room except at night). Once I noticed signs of growth I dipped the cutting in rooting hormone and placed them in soil. I didn't loose a single cutting by doing this, did it help? Unclear, no control group.
