Dendrobium Kingianum conflicting care info

[Raqsharqi]

Another new orchid to my collection is a Dendrobium Kingianum. It also came with absolutely no care information. I wrote to the grower and got no response, so I looked the orchid up online, and the information I got there says to cut way back on water from November to spring...which could be February for me. One says to treat it like a cactus, which to me means "if it rains, it gets water." I decided to phone the grower yesterday and was told that I have to water it and feed it the same year round, and if I don't do that and cut back on water, I won't get flowers and the plant could die. I'm a newbie. I thought I knew what this plant needs, but the information is SO different I don't know what to do. (For what it's worth, the grower said I should treat my Ascf. Twinkle the exact same way....water 1x week, bright light, south window)
