This is my eventual goal....

that is an admirable goal... not sure what your level of expertise with orchids is..

have grown successfully this plant and other dendrobium species in South Florida

and my recommendation is 'a screened pool enclosure' is a good place to start. Notice that these plants need very bright light but short of full sun, have a somewhat dormant winter season with reduce watering and very low feeding. They can handle cool weather but temps close to freezing can damage plant. They are also heavy feeders when in active growth..By the way, you posted on the wrong forum, there is an active orchid forum here that will enlist many more replies, here s the lnk

Here is one of my dendrobium species , this is chrisotoxum, similar culture to your plants and in enclosed environment that has very bright light

Hi Ben...

Thanks for the reply. I have been growing orchids for about a decade, but mostly Catts, zygos, and Phals. Just got hit by the Den and Coel bugs. I simultaneously posted in both forums but was more interested in Floridian weather with Summer heat/humidity and high night temps/high rot pressures. Beautiful Den. Chris.... They sure get big.
