Interaction between light, humidity, and temperature

[rbarata]

Any info is greatly appreciated, and if anything I'm doing looks too far off let me know (with the Reasons why, please).

Although each parameter is somehow related with each other, their interaction in an environment is something really hard to explain (considering all of them).
The best is to learn it by trial and error. Introduce sligth variations in one of them and observe how the others change.

Ok, thank you. I wouldn't think that a temp drop of only a couple of degrees would matter (unless 72-75 is too cold for constant range)...but the humidity being a bit higher could help with growth or water loss with the higher light, esp during the Winter when my apt humidity drops into the low 30% range. So I think I'll just set it and forget it now...as long as the orchid still looks good.

I often tell people that benign neglect is a good standard to live by with tough plants like this.

Generally though, plants will take up more water during the day while they are photosynthesizing. They will also transpire more water from the leaves, and this will increase humidity near the plant. I don't know if any of the plant transpiration cools the plant, but moist media and a damp clay pot will evaporatively cool the root zone, especially if the air is dry. Unless it is bone dry winter air, I don't worry too often about humidity, but I would probably be more concerned if I lived in Arizona instead of Georgia.

Thanks for the explanations.

I guess I was thinking ahead to Winter when my apt humidity drops into the low 30% range, as mentioned in my reply above. And I was concerned maybe my temps are too low. But I've gotten replies to some other posts and it seems like my parameters are just fine. Certainly my orchid's growth would seem to indicate that!

So I'll aim for the benign neglect thing.
