My Phal and Paphiopedilum orchids indoors hang on a pole, saves me space, keeping them vertical, by our west facing windows and north facing sliding doors. I just draw the curtains in the afternoon when it gets way too hot in the afternoon and there is a ceiling fan to provide air circulation when I cannot open the windows due to the heat. The blooming Dendrobium Roy Tokunaga 'Spots' there is a new one I got this year, love how long those blooms last as well, but after blooming it is now outdoors in my growcamp. It is also in that corner area where my Hoya shooting stays, just beside the pole.
