| Kevin, these are moderate temp, high humidity plants but they seem to be adaptable....very adaptable if Cynthia can grow them. She's pretty far from moderate temps and high humidity :>)
My GH seldom goes below 40%RH and mostly it's 50%+. I actually hope for low RH outside so my cooler works better. I've located my S powellii so that it sees less than 80F at nearly all times although for a few days each year (mainly August) they see 85 or occasionally 90. I do try for 60F at night (or at least as low as possible) and the plants don't mind that at all even though in habitat they probably do not go that low. |
