I know... I know... the last one who tried to make my dragon eat out of his hand has now only one hand left...:rofl:

Roly, things are getting ugly for you....!!:lol:

Wow, that one is stunning!

I love the makings on the lip contrasting the white.

Mauro, how often do you water this mounted one during the "dry" season that amaliae undergoes in the wild? How about the ones in moss? Are they still happy? Thanks!

Chris, I grow my two (still!!) mounted nobilior along with my Vandas. So, you can imagine they are watered every single day, the year round.
Those in moss are also watered during the dry period (from may through mid-September here), but in a less frequent basis, two times a week. But, you need to know that they are planted in clay pots in a mix having more or less 30%-40% of Styrofoam peanuts. Through that addition the moss does not compact, I manage to have good drainage and the vital air around the roots is easily renewed every time they are watered. Yes, they are happy!

Rosim. I'm glad to see your cultural comments above. By coincidence, I just gave some advice this morning to someone in the SW US concerning his C. nobiliors and his amaliae. Your climate in Brazil is vastly different from our near tropical climate, so I don't like to tell someone elsewhere how to grow their plants. Like you, I prefer to focus on what I think the plant's needs are ... based on my own experience.

Many people seem to believe religiously in the drought in winter theory, based on the dry natural habitat in winter. However, I think that because of the elevation of the habitat, atmospheric inversion must bring down moisture in the form of night dew for the plants. Whether or not this is the case, like you, I have also found that the roots need a lot of exposure to air and light and need frequent moisture. I find that our amaliaes are a bit slower growing

I also hesitate to tell people that the roots need to "dry out" between waterings, because that may imply dessication to some. I also stress the need for frequent watering of the roots if a plant is mounted or in a very coarse and dry medium. But accompanying good air movement is essential to prevent roots from staying constantly wet. And I do emphasize the need to control but not stop watering if temps are into the 40's.

If we meet these needs of the nobiliors and the nobilior amaliaes, we can grow them successfully ... whether it be in your climate or mine

I see we think the same way, Catwalker, especially in relation to telling people living in different climatic condition how to grow their plants.
The points you raise in you post are good as well as the way you deal with them.
You are also right as to the dry period question as far as nobilior and other orchids of that region are concerned. The dry period is real, it happens, but it means that it doesn't rain, not that the plants living there don't receive any water. You are right again as you mention that there's the night dew, especially in the dawn, supplying some moisture to the plants. If that were not the case, it would be intolerable for these kinds of epiphytes to stand five months loosing water every time they had to open their stomata to capture the vital CO2 for their daily photosynthetic needs.
Just on a side note, I don't like the idea of letting the roots dry out between waterings too. If you don't have a good understanding of what 'dry out' means all you get is a slow grower plant. This is especially true with seedlings and young plants for obvious reasons.
