I really appreciate all the encouragement since I have lost a many orchids in the last 30 years of trying to grow orchids in the house with very low humidity in the Winter. So this started out of frustration for orchids drying up or rotting if I gave them enough water in organic media. Now I have no organic media at all. Everything, including my bromeliads and house plants are either in water culture or Semi Hydro in lecca. I don't think I would have ever tried this if I had a greenhouse or could grow in Florida or the tropics.
I made several posts on my water culture experience and suggest you check out my latest post. I will then be glad to answer any specific questions relating to your concerns.

Jerry, it seems from your albums that you are successful in growing a variety of orchids very well. I would also be concerned about mosquitos if I were to grow them outdoors. I woke up one night dreaming of mosquitos and found that they were biting me. A female must have snuck in through a loose window screen and took advantage of the wonderful culture media.
Camille,
I am glad your dendrobium is doing well. I don't remember any dendrobium I have tried that did not do well. Since the mother plant of a Dendrobium hybrid in lecca got too heavy for me to lift I gave it away and kept a keiki I put in water culture 5 months ago. To my surprise it is blooming now with much larger flowers.
