Love the Epi! The terete Vanda should get FULL sun, no shade, all day, and keep the roots moist like a semi-terrestrial. Professional growers grow them in mulch.
For number 3 for some reason the genus Liparis comes to mind when i see it. Ive never owned one of them and this is just a shot in the dark so i could be totally wrong. It just looks like something ive seen in an orchid magazine or on ebay or something..and thats the name that pops up in my mind lol.. Could anyone confirm?
