Phalinopsis mannii in S/H

[OOAJ]

Hi all, I was curious about growing phal mannii s/h. I bought a seedling about a year ago, and have had it growing s/h for about 8 months now. As far as I can tell, the little mannii seems very happy there, it's growing new leaves on a regular basis and it looks to have very good roots.
My concern is that I was doing a little more digging into the culture of the species and it says that mannii need a dry spell in the winter to bloom. However, another source said that while their natural habitat does provide a "dry season" with minimal rain, they tend to grow along rivers and other water, so they don't fully dry out.
I feel like the plants is getting close to being first bloom size, and would like to try and get it to flower next spring if I can. My question is, since I've been growing s/h, will this hurt my chances of getting a bloom? If so, is their anything I could do to give it this dry spell, such as letting the reserve water in the bottom of the pot deplete, or will that present greater risk to the plant?
As always, thank you in advance for your thoughts.
