Vanda Sansai Blue with discolored spots on leaves

[rastafouni]

Hi Mario,

I think that Sansai Blue and Patchara Blue Delight should be ok in Mérida's climate and that the conditions that you describe are fine too !
On the photo that you display maybe the plant receives a bit too much light and you should reduce for a while light intensity especially with Yucatan's strong summer sun.
