So I received this P. 'Titan' in the mail a few months back, and it immediately shrank down to that size and turned that gorgeous red color. Is that some form of hibernaculum (it shipped through 40-50 degree temps) or are my growing conditions just so off that it's going nuts?
Currently it's in a 1:1:1 mix of peat/perlite/vermiculite, being watered under the tray method -- about a 1" bit of water in a "deep dish" saucer at all times, usually hitting 1-2mm before I fill it up again. It's in a 5.5" glazed pot. It's under T8 -- now T5HO -- lamps on a 16 hour photoperiod, although for the month of december I had dropped it down to 14 hour days. With the mylar lining, the rack is staying in the 80-90 degree range during the day.
It's my first time trying vermiculite, so I'm a bit worried. In the same pot is a P. Gigantea that is staying rather small (under 2 inches) so I had originally thought it had gone into winter mode due to the trip through the post office in cold temps, but I showed that picture to the friend who shipped it to me and he didn't even recognize it.
