James,
That was why I went back to the principles, rather than just the advice, and you have illustrated the point I was trying to make: You understand the principles and requirements, and you meet the humidity requirement by living in Houston. I would have to meet them by using a tent, greenhouse, or some such thing. We have the same requirements, but different solutions. Personally, I like my solution better - it beats living in Houston. But for the last three days, I have been misting and shading the newly rooted cuttings that I potted up because the temps on Saturday were 69-70ish, and yesterday and today they are 80-85 (unpredicted by the weather man who saw 70ish all week with a dip to low 60s on Wednesday). Conditions changed, so response had to change.
Again, that was why I tried top take it back to the principles and goals, and you have illustrated that well.
