All Forum Readers, for clarification regarding the terms used to indicate temperature conditions, it's probably worth pointing out that the terms "warm," "intermediate," "cool," and 'cold" refer to specific temperature ranges for orchids.
warm = 80-90F day; 65-70F night (25-30C day; 18-20C night)
intermediate = 70-80F day; 55-65F night (20-25C day; 12-18C night)
cool = 60-70F day; 50-55 night (15-20 day; 10-12C night)
cold = can tolerate less than 50F at night (less than 10C at night)
Depending on the geographical area one lives in, some or all orchids may or may not be grown "with heat" e.g. in a home or heated greenhouse, but growing "with heat" or "outdoors" etc., etc. isnt' what determines whether an orchid is intermediate, warm, or cool growing. It's the plant's temperature requirements that determines that.
