Vanda leaves are just starting to become leather like.

[Paul Mc]

I'm a complete newbie to Vanda's, and I haven't yet found the "right" vase to try vase culture with. So, I've had mine outside hanging in a spot that gets morning and evening sun but dappled shade throughout the day.

It is Vanda Pachera Delight (Vanda Karulea X Vanda Gordon Dillon). The plant Identification Number is (PID): HV19NBS - not that I know if that's a number they gave it or something else.

I got it right when the temperatures dipped down in the daytime from the 100's with heat indexes above 110F. When the temps were in the 90s during the daytime I would water two times generally, once in the morning and then again when I got home from work around 5pm.

It's been doing alright, until we hit this new 100+ heat wave. I'm honestly not sure what the night time temperatures were, but there for a while we were hitting the upper 60s and lower 70s for a few weeks. Looks like we're supposed to be in the mid to low 70's at night for a few days, then dip in to the mid 50s and upper 60s.

I've noticed many of my orchids are suffering from heat stress (slightly yellowing leaves) and a few phal's have started to have the leather leaf look. Now this particular vanda is doing it. As a side note, I have another Vanda, it's a coerulea and it is not exhibiting the same signs and has pretty much the same environment.

Is this heat stress or am I potentially doing something "wrong" (not necessarily my own actions like plant placement, watering, but also potentially humidity, environment, etc...) It's in a hanging basket with no media.

Thanks everyone!
