I purchased this Paph (Paph Waipunga [Kerry Anne x Sharden x Seacliff] back in June. It spiked about 10 days ago and just won't open. The greenhouse temperatures run about 67 ~ 72 depending on the sun/clouds during the day and about 62 +/- a couple of degrees at night. In your humble opinion, could these lower temps be responsible for its delay in opening or how slowly its progress or could it just be, "It ain't gonna open!"
