Vandas in semi-hydro?

[Gin]

I would want to know how long they have been s/h , where the person lives (what state) warm ? and if any have bloomed . Another thing the roots can get very long on some of them 6 foot or more , would it require root trimming or a wash tub I know Motes in Fl. trims the roots on ones in baskets or on wires , trimming and putting back into s/h . sounds risky . Just curious . Gin
