Mickey, whether you are successful with a particular plant is not determined solely by the plant. How well the culture technique "meshes" with the rest of your growing conditions to meet the needs of the plant is what's important.

That said, I - with more S/H experience than anyone - cannot grow vandaceous plants that way. I do have customers though, that are successful. Most of them are growing in very dry environments, and I have no way of knowing how rigidly they adhered to the technique. I have a nearby customer who wins awards for her succulents and cacti grown that way.... Who knew?
