Last summer I lost the roots on Hoya griffithii Silver and tried something different. Rather than rooting one cutting at a time in a small pot, I took several cuttings that I rooted into a large 7 inch pot. I am using 100% coconut husk chips, and now I have a plant that is well on its way to becoming the nicest specimen that I have ever had of this H. griffithii clone. It is so unbelievably healthy and vigorous!
