Considering I stated that I don't own one and thus haven't bloomed one myself, I've got no reason to defend what I shared. I guess since the advice has been varied, even on the web overall, the thing to do is put it in less light and gradually increase it if the plant stalls or never blooms? It seems like so-called "bright diffused light" is the answer for most unless it's a true low light or full sun plant. I personally don't get to be too picky about it (shade cloth percentages etc.)--in most cases, it's either a lot or not much light for my plants, so I think in simplified terms and give everything as much light as I can short of visible plant stress. All I can say, is when I see or hear something's needs compared to that of an ascocentrum's, I kind of tune out the concept of too much shade. When in doubt though, by all means--listen to the pros!
