What Cymladye said.... Low temps are not as important as high temps....By that I mean keep cool. High temps will make them stress. Try to keep under 78 and above 45. They tend to like cooler temps way more then warm temps. Fertilizer 1/4 strength once a week. Keep constantly moist not too soggy or too dry. Keep humidity up in the 70% range. Good air movement well help.
