Dave, I also have a Eric Meng cross that I purchased in bud last week. Mine is about 50% open now. I would say that within two weeks your bloom should be fully open. Paph. Eric Meng must be a very strong light colored paph. My cross is with Paph. Black Buddaha. Mine bloom looks much lighter color than I was expecting ? My looks more like a Paph. Supersuk Eureka X Paph. Raisin Pie Hsinying in the coloration. I should be able to post some photos by mid week I hope. Have Fun, Rich
