When to Unpot a Vanda?

[D&S Mabel]

I own a number of vandas, all of them acquired already bare rooted in baskets - the most common way of growing vandas in our weather conditions.

I recent bought two vandas that actually came in pots and I am unsure how big these should be before I also move them to baskets barerooted.

This V. Tricolor suavis is in a 4" pot, is 10" wide and about 7" tall. Looks big enought to me. Yes?


This V. luzonica is in a 2" pot, is 3" tall by 4" wide. Seems alittle small yet. Yes?


In either case, what should I be looking for in deciding when a vanda can handle being unpot and grown barerooted?
