Dendrobium Aphyllum, versus Cucullatum (new name)
 

This dendrobium aphyllum with quite spectacular blooms
just started flowering here. It has a fragrance like a freshly opened natural honey pot! Enjoy!

Cheers, Michael

I think they're Dendrobium primulinum (the kind without a yellow blotch).
Aphyllum has petals broader than dorsal petal and with primulinum sepals and petals are about the same width. Primulinum has also big canes (like on your picts) and aphyllum thin canes.
Are you sure of the ID of this plant ?

Anyway, they're beautiful !!!Congrats ! In advance by comparaison of bkk, here both primulinum and aphyllum are still not blooming.

Once it starts to bud how offen do you water it?

For myself, I start to water them but just little , not too much.

Is that every day or just weekly

let's say 2 or 3 times a week but it is VERY hot right now in Bangkok. I think it can be less if lower temperatures.

I live in south Florida and it will be getting hot. I will try twice a week and see how that does. Thanks for the help
