hi, thanks for your answer...
i'm from southern italy..calabria, near the see...
yes 45 degress are too much, but i think with a good humidity orchids shoult be ok!
i have some photos... but my camera now don't work!
now i have to organize the space on the terrace with consoles!
i'm growing intermediate orchids like cattleya, laelia, dendrobium... i post my rchids liste!
