Stanhopea Growth Timing and Duration

[Oculata]

I posted a topic on my blog regarding the growing conditions I have, and how some species such as S. tigrina have several growth cycles a year, while other species such as S. insignis don't. This could be due to the adaptation of some species to my climate since I grow outdoors, or that some Stanhopea I have are more mature than others, and therefore grow more frequently. I was just wondering if other growers have noticed a similar trend in certain species, or if you have greenhouse conditions perhaps the Stanhopea grow continuously throughout the year? Any input would be appreciated.
