I liked the article. I grow lots of them and have the same issues as you fleur. There was a guy that I bought them from on ebay who gave me good advice but I just don't seem to find a magic bullet to get them happy. I think they would be a major favorite of mine if I could figure out how to get them to thrive and flower. This year I am growing them in more light and heat. The one exception is lucasianum which blooms for me. I have reverse osmosis water and fans directed on them but they are languishing.
