I don't remember how long the flowers lasted (it bloomed around May 30, 2020, and I haven't gotten around posting it until now), but it was probably 1 week or so. I grow it at cool-end of intermediate. As I mentioned in the blog, Wodrich's book recommend 2 months of dry rest in the winter. I reduce watering in the winter, but not as severe as the book suggested. I haven't measure the light, but I think it is fairly weak.
