Thanks, Lance. All of what you just said makes sense to me. I'm not a scientist, and can only say what my own experience is. I'm not subjecting my orchids to extreme cold, but I have observed better root growth and stronger plants since switching to k-lite a year and a half ago. I'm doing a lot of my re-potting now. I have quite a few Paphs that haven't been repotted since 2011, but they were in orchiata and non-organic media. Although many old roots were rotted, there are lots of new roots since changing fertilizers. So I'm planning to stick with k-lite.
