I'm currently growing some tilandisia in my terrarium under a CFL. They are right at the top under the fixture and provide shade for the dracula, lepanthes and masdevallia below them. My oldest of the three is growing like gangbusters. I'm primarily concerned that my terrarium will be too warm. I have a dracula Lotax in there. It grows pretty well but these are more tolerant of warmer temps. I have seen the temp in my terrarium get up to 79 degrees, but a quick misting always brings it back down to 73.4 which is where it usually sits.
