well for phrags, they are a little different sometimes than a lot of other orchids. for me depending on the lineage of my phrags, if they are more than 1/2 longifolium, they sit in a tub of water that is half way up the pot itself and they love it (i gotta top off the container every 2 days or so b/c it just sucks up all the water. however with ones which are hybrids of caudatum, wallisii, or besseae, i dare not sit in them in water at all. as for the ones i do sit in the water, some roots will rot b/c they cannot adapt to the new conditions but the new roots will come.
as for the climbing habits, some phrags are just prone to climb... their bad habits unfortunately so dun freak.
Grouville = Eric Young X Hanne Popow
Eric Young = besseae X longifolium
Hanne Popow = besseae X schlimii
this means ur plant is 1/2 besseae, 1/4 longifolium, 1/4 schlimii. if it was me, i would not sit it in water at all. i'll just water a little more frequently since your's in straight s/h
