Where I live also similar to your condition.
I grow the following succesfully:
- Phalaenopsis amabilis, amboinensis, corningiana
Although my bellina and gigantea have yet to bloom, they are growing nicely.
- Cymbidium finlaysonianum
- Dendrobium stratiotes, most spatulata also suitable to lowland tropics
- Vanda limbata, tricolor, suavis
What I listed above are native to SE Asia. Should be easy to obtain in your nearest orchid vendor. Besides the above, bulbos can be a nice addition to your collection although the scent can be unpleasant sometimes. Examples are: Bulbo echinolabium, becarii, medusae.
Look forward for your new chids.
