@Cathy.. thanks. I also thought that it was a kagawara Christie Low, but seeing the previous posts of Kagawara Christie Low here and comparing them to mine, I would say maybe it's not. The sepals of the CL are more rounded.
And Ok, I would make sure to spray fungicide. thanks..

@Willeke.. thank you.. yeah, I would keep an eye on my orchids so that the little girl will no longer pick orchid flowers in my garden!! hahaha

@Moja.. thanks.. unfortunately, I was not able to go at the orchid show last friday. Hopefully, maybe anyday this week I can visit it before the show ends..

@Carol.. Thank you. I am crossing my fingers, I do hope so that this would be a frequent bloomer. I have other Vandas that have not produced spike for 3 years now..
