I'm not sure, but I think you grow in your home. What kind of light do you use? I have finally started to have better luck trying to flower mine when I raised mine up closer to the light. I now have 'Laura Bush' in bloom and 'Princess Mikasa Indigo in bud. Two out of three isn't bad....for me.
Marilyn, I grow all EXCEPT the Vanda at home. I don't have enough light at home so I grow my Vanda in the greenhouse at work...thankfully the staff don't mind...they enjoy them too!
