I grow P. bicolor and P. ignea and both bloom and do well for me. I grow them in deep five gallon pots, in a mixture of mostly pumice, with about 30% potting mix that is mostly peat (no wood products). I allow the pots to dry out almost completely in summer and have had no problems with rot. They get fertilized with a soluble fertilizer about once a month while in growth. I do not provide extra heat and my greenhouses go down to about 35F on cold nights, but heat up to about 70-80F on warm sunny winter days.
