Vivienne - I may be the odd man out here, but I have never drooled at the thought of a having my own greenhouse. I love living with my plants in the house and on my patio where I can see them; it's just too easy to do here. With a greenhouse comes a multitude of other problems that need dealing with and as much as I love my orchids, I have too many other hobbies to make them my only time-bandit! I love to visit atriums; the San Diego Zoo and Wild Animal Park have a huge atrium with lots of the world's endangered plants growing inside. (including LOTS of orchids and a carnivorous plant bog) ALL I want is for ALL the growers to be near ME so I can browse their farm and pick what I want from thousands of plants. Am I asking to much?!!?
Interesting fact: as famous as the SD Zoo is for it's animal conservation and breeding programs, they put the same energy into plants and spend a lot of time and money saving plants from extinction. The PLANTS at the zoo are worth 100X that of the ANIMALS! (monetarily speaking)
