Hi Puffy
Vandas in their natural habitat (eg. Thailand) bloom and grow continuously all year round, so it really depends on your growing conditions.
Are you growing indoors or outdoors? Do you have heating?
There are some 'easier' bloomers, ones that are more cold tolerant ie. vanda coerulea hybrids.
You may want to try Asc. Princess Mikasa, Vanda Sansai Blue and Vanda Blue Magic.
I was able to bloom Asc. Princess Mikasa Blue and V Blue Magic within 3 months of purchase- vase culture. The blooms are really worth the effort!

What makes a vanda bloom? Well, lots of sunshine (6000FC), water/ humidity, air movement and a variation between night and day temps (8-10C).
What vandas are in your collection?
BTW, welcome to the OB!
