Mine are both TC. In the winter, it's about 82ish during the day, 70 at night. In the summer its about 88-85 all the time. I really don't know the problem. One's in sphag (what it came in) and the other is in peat/perlite/lava rock. I'm honestly getting a bit irritated because everyone but me has huge awesome bicals lol. And with my conditions, you'd think they'd have gotten to that point by now.
Trying to grow it large. Had a Bical with about a 20' vine and 4' leafspan. Plant was huge/could not move. Lost when Hurricane Ivan totaled my greenhouse. I had 6' of water where my greenhouse used to be. I couldn't even find a piece to take a cutting from. Oh well, I like to grow small plants large.
