Consequences of too much light? (not sunburn, though)

[dbarron]

Yeah, I definitely notice a purple tinge to my oncidium 'gold dust' when I give it more light than it's acclimated for. It does fade in a couple of days if I reduce the light.
I try to push them toward higher light though (lol).

Regarding B. nodosa, I saw a HUGE clump, I really mean huge, covered with hundreds of flowers in Honolulu in October. It is a bit higher elevation, but still, it was growing outside on a tree and exposed to full sun. All the leaves were green.

Speaking of purple spots or tinge, I am not sure if it is due to bright light. It can also be due to cold or magnesium deficiency. I'm not really sure.
Certain ondiciums or miltoniopsis, when they get a lot of light, they develop purple tinge but they do not go away unless they are moved to lesser light.

Dendrobiums- nobile hybrids (you said you don't like the smell of their flowers?) take full sun fine, but your recent purchase type, they will definitely be cooked. Just a word of warning.

Given my extremely pale skin and tendency toward burning myself, I am extremely careful with my plants!!! I did burn that one phal, but never again.
I know my b nodosa is getting spots from sun because they appear after a few hours in bright light and fade after a few cloudy days.

Which recent den purchases are you referring to? I got a couple unicums, an antennatum, and two noid den phals!!! Hah!!
I am keeping all of them in bright indirect sun, and the antennatum and kingianum I have get some lightly filtered direct sun on sunny days. They seem to like it... My kingianum (which I am suspecting is actually a berry oda) is putting out 4 new flower spikes after blooming only in January!!
