Those are gorgeous WTC with form and colour approaching those of the standard cyms. I'm just starting to grow cyms but it is very difficult to get the HTC types. Our day temps are in the mid-high 30 C (90-98 F) and nights are 25-32 C (75 - 85 F). So far Golden Elf does well here. I have recently acquired the HTC Chen's Ruby and Golden Vanguard in bloom and expecting a few more when our vendors get them from Bangkok. Thanks for posting.
