You have my permission. I have written a so discursive considerations because I was worried that it could occour the same "carnificine" with our small ones, as much as during the 19th and the beginning of last century with the excess of humidity and heat that "cooked", or rather "boiled" millions of Cattleya in european greehouses, exactly because of deficiency of information and a generalistic hearsay the tropics are such-and-such hot and such-and-such humid. In some of messages I could forsight a "inhaler device" being prepared for our little ones, even in aquarium !!!

I submitt TO YOU further considerations because perhaps also I was too short in making considerations about fooding and natural healing conditions that natural individuals have.
For me, orchids are eating their annual banquet when the first rains bring to their roots the bacteria, fungus, minerals etc that is carried drown by the water that, at the same time is clearing of the dust, dead bodies and rest of organic and mineral the remaining tree leaves (that now can support less weight and see more light), and clear the branchs and trunk in a cleaning situation. The fungus that now can grow also provide a "penicilin" to damaged tissues of broken parts. A more drasting sittuation occour with the strong autunm winds that stripp the dead leaves and put down dead trees and old overweight liana-full branches (now the tree-roots can recicle all that fallen organic matter with the soil microorganisms - which for me also represent the forest). I consider the most important property of living organisms is the healing property they have.
So, again, they do not need fertilization and protection against bacteria, fungus, etc all the year long as I frequently read of making these addings on a weekly basis.
If you think these last considerations have a solid merit, and are not an excess of zeal, you can add to my previous comments that were more important.

Thanks so much for your insight.  I would like to ask permission to reprint this in our newsletter.  Also, I can try to help you identify things if you e-mail me privately with the photos.  I am not sure photos can go on this list.

To Linda and other afficcionados:
I would like to help you to understand why and what are my natural conditions that make my ranch so prolific in native Pleuro, Octomeria, Isabelia, Barbosella, Oncidium, Leptotes, Masdevallia, and other micro and macro ones, up to 50 different species in a 20 acres ranch.
1. diversity of vegetation, light, humidity in a hundred of feetdistance: low trees, medium to bright light favors the small ones that are quickler to occupy devasted land and low trees (that normally occurs when an old big tree falls, clearing a lot of other trees in its way down). During the period of forest regeneration, tens of years, that is the time for Pleuros. Some big orchids that come with the fallen tree survive and even become terrestrial  species, but not the small ones.
Big, high, old trees do not have orchids from the roots up to medium, high branches that are on a region of winds, rocking thin branches, living in consortia with cactii, bromelids, ferns, fungus, insects and small animals and birds. Under the forest dim light there exists big treeferns and terrestrial orchids that only bloom for a short period of time and then disapear.
2. wind or breeze along days, chiefly during noon to evenings in order to dry the thin roots of Pleuro. Mine do not like constant rain or 100% humidity that occurs only about 10% of the year and during hot summer (max temp 28ºC). Daily temperature difference is from 15 to 25ºC along the changing weather, be it spring, summer, autumn or less than 10ºC during winters.
3. the winters are cold (-3ºC to 15ºC), as normal range, without precipitations for 15 - 45 days - this year: for 30 days without rain, BUT, constant morning mists from 6 up to 10 o'clock in mornings. Dew occur every day that doest'n rain be it spring or autumn. Half of my trees loose half to totally their leaves during winter (semi-decidual trees), letting more light to the forest floor and lower branches plants.
4. annual precipitation: > 2500mm, chiefly in dec/jan/febr.
5. altitude: plateau of 1000m above sea level.
6. 30 km distant from the sea, separated by a sierra.

So, there is no constant temperature, humidity, light, wind conditions for those plants. As every living organisms they need ciclic annual conditions. They have to store water and food for dry periods, have a dormancy period, a flowering season (some blooms in winter others during spring, but the majority of my ones is during autumn). Others bloom all the year round, for years - the same branch produces flowers after flower till one is polinated, the capsule begins to grow and the branch do not produce any other flowers. The plant, instead, produces  another flowering branch.
You may consider absurd, but if I were to create an artificial greehouse for some equatorian, colombian, brasilian orchid, I would control my greehouse climate by the CNN weather information on the climate-of-the-day of the nearest city my orchid came from: wind, rain, humidity, min/max temp.

I would like to append some photos of different light situation, humidity along the year, but I think it would not be possible....and I would post some Pleuros I would ask for help to classify.
Sorry about these long considerations.
