Vanda Pachara Delight 'Pachara'

[early]

My two vanda seedling arrived. They look health in bark/charcoal? perhaps. They were moist on arrival and in good shape. two years probably before a stem/blooms.
Is there any reason to, in time, repot them in S/H?

My first thought was to leave in two in pots and let them get use to a dry climate, but keep moist and high humidity. I have room is my bathroom if I move some of the bloomers out to living room and try to keep the humidity up. No problems in the bath room, fan going, cool at night, normal house temp in day, an humidity going several hours adjusted to keep it below 70.

I know nothing about Vandas. I bought them because they when bloom with be close to a true Blue. I have the id tag.
Any help with Vanda, 3 inch seedlings greatly appreciated.
