I basically just open and close the zip down flap in the front.
If it's very windy or rainy, I close it.
But I make sure it doesn't stay closed too much for air circulation
It gets some decent morning sun, but none directly on the orchids, except the epidendrums(they seem to like a bit of sun).
Otherwise I move them all around a bit and utilise the natural shade from the trees in my garden.
not too sure about the temps, I havn't actually measured!
It is a pretty warm climate where I live, if not a bit dry.
I guess I'm going for the au natural approach to growing orchids. I seem to be doing okay so far.
Like I said, basicaly a beginner
