Cannot help with culture but Vasco. Pine Rivers 'Pink' should be a little bit more tolerant of coolness during winter because of the Rhynchostylis coelestis parent.

You are more likely to see various clones of Vascostylis Pine Rivers at shows around these parts than "Vandas" that require all year warmth.

I'm trying to grow a few "cool tolerant Vandas" but mine are all babies.

Omg all year blooming wow yes that is exactly what I have. how long are the roots? Do you think cool temps inside by my porch window it would be happier then in 90-100 temps outside 100 % humidity 80-90 at nite ?
I'm thinking it might like to come in as it gets hotter and hotter here ?

Cooler tolerant means lower winter night temperatures mostly in the 40-50F range. Summer is not a problem because they have spent summer in the glasshouse. Your orchid might be fine outside all year in SW Florida?? Never been there so i do not know.

Winter is a big problem for some Vandaceous here because of low humidity during the day and low temps at night.

It says on the tag never below 40..but in my experience under 65f as with Phals I bring them inside ...

65F!!! Casper milk toasts. 55F is the usual minimum for most orchids. What happens during the day is also very important. If it stops at 55F not good. If it climbs to say 80F no problem.

Phals never go outside in this climate. Vasco. Pine Rivers is just about to be brought inside to spend "winter" on top of the tropical fish tank getting filtered sunlight and warmth.

It sometimes get below about 5C in my heated glasshouse before the heater comes on at 6:00 am but this is simulating the conditions in some tropical places where the nights are cool and day temps always lift.(tropical savannah)..

I have 2 Pine Rivers; the blue and red forms. Very nice photo, Nancy.
Like Arthur says, the Rhynchostylis coelstis parent would contribute cool tolerance. This species forms 50% of the parentage.
They are grown here in a basement "greenhouse" and misted (actually watered with an automatic mister system) regularly, with night temps 60-65F and days 75-85F approx.

The burnt look of the longest root could result from possibly touching the floor/ground, and picking up anything that could be caustic or cause it to be injured, like excess fertilizer, friction, etc.

You guys are amazing...However years ago with other vandaceous..long rooted stems I saw this too thinking it could be from fertilizing..There was a great Orchid house here mostly all from Thai land..Roots dripping on the ground awesome sight....So much maybe they were reaching to the ground for more water at times..but he had the automatic sprinklers systems just an awesome great place to go nuts in ..
I had the Rychostylis Gigantia OMG what a beauty ...I think with the amount of heat and often stagnant heat here I will soak it in my sink every other to every day depending on heat in my sink.
It seems to be content..I will also try as it grows hotter here at night bringing it inside into 78 degree nights.
We all have our weather issues for sure.
My other Vanda is living beautifully in the vase as mentioned in another post.
Now it is growing new roots and new leaves .../maybe it will bloom...So it must be too much heat here for the conteness of these vandaceous plants.
I believe years ago through disease or insects like mealy or scale not enough water I lost a fortune.
I felt it was from this grower I'm talking about from Thai land...
Now no more from him but maybe they will stay healthy...thx Guys.
I see Alturm you like these ..try the vase experiment it is fun to watch ....J'aaime
