I read that as referring to the 'ideal' temps for phals, that she is having trouble maintaining that.
So yeah - if temps are not less than 50, probably not a worry

I have the thermostat set at 55 for overnight, and plants are on windowsills, so probably a bit chillier there. and daytime temps inside usually 60 - 64 - my two small species phals don't grow all winter. I don't know if that's due to the temp or if they just don't grow over winter anyway. My 'mini' noid phal has been growing all winter, tho probably slower than in spring/summer.
