good question Charity. I'm interested in what folks have to say on this topic as well.
I've never had much luck with Paph's either.
Quick story....... I have been sorting through my plants and just found a paph mixed in with my Phrag's (which people tell me are amazing), and it had a big fat bud on it!
None of my others which are all on the next bench over do much of anything. Phrags get fringe of misters benefit and maybe slightly more light. Is that what they want?
