Rosie, I have kind of a mixed bag going on here. I have some potted in large CHC, and some in fine. I have a bulldog I purchased in the spring that the grower repotted for me and it's in very large fir bark. They all seem to be doing fine. I do notice I don't need to water the ones in finer grade as often as I do the large grade. Most of mine were repotted a year ago and I did notice that growth seemed to slow down quite a bit while the roots re-established themselves. Now that it's been about a year since repotting they seem to be growing normally again.
Not much help I know. Sorry!
