Erce, when I went to an orchid grower and asked for specific plants that could grow on my windowsill, he told me that Neo. falcata would do fine. I now have a Vandofinetia 'Pat Arcari' growing well (just finished blooming) and it seems to adjust fine. I have noticed that this plant was quite sensitive to changes in environment, I moved it 3 meters i my house and all but 1 bud survived. I do think that Neo's and it's hybrids is one of the adjustable ones

. Ofcourse they would like a more tropical environment better, like in CoolPhrogs orchidarium

Why don't you ask the grower you want to order your Neo's from, tell him/her the specifics of your growing area and see what they advise you?
