Ken, I actually had spectacular results with the keiki paste. Every node that I applied it to started a new plant. I put it on a bunch of my phals and also on the flower stems of a couple of my Phaius. I had keikis coming like crazy. Then April turned into May, it got hot and dry and Pffftt!! They all turned brown and died.
I think if I'd paid more attention, maybe brought them indoors to control the temperature and coddled them a bit, I might have succeeded. I still have the paste, maybe I'll try again.
