I have some very leggy vandas, that do not show well in their hanging baskets. I have been adding bromeliads to the baskets, which improves their appearance and by keeping the cups of the bromeliads filled with water it also adds more humidity to the chids. Don't know if this information will be helpful to anyone, I just wanted to share my little trick.
Something else you could do if the top of the plants have enough roots. You could cut the top off and plant it separately. The bottom section would put out keikis.
