Heat and light loving orchids for top of tall terrarium

[estación seca]

Do some reading. Many live on rocks or sand in sun. They tend to be very white, not red. Off hand I can think of T. araujei, bergeri, concolor, intermedia, ixioides, paleacea, purpurea, straminea. They need to become dry each day or they are likely to rot.

Tillandsia tectorum wants very high light, but cooler temperatures and low daytime humidity. Tillandsia ionantha usually wants less than full sun, but if it doesn't get too hot in there, might do well.
