rbarata,
just click on my signature and you have access to my blog where you can see the history of this particular plant. (Use the search, tag 'eulophia'. From no leaves at all to full leaves. The plant now is small. In summer is will be some 35 x 35 cm.
Perhaps. It had a low of 14ēC during dormancy and maxima are now around 24ēC. I wouldn't call it hot. But the plant thrives.
Maybe it would be happier with hotter tēs.
