This is a discussion on Terrified to repot my new Rossioglossum within the General Orchid Culture forums, part of the Orchid Culture category; Sorry to hear that Kelly, the plant seems to have been growing under excellent conditions ...
Sorry to hear that Kelly, the plant seems to have been growing under excellent conditions from the way that each new pseudobulb is nearly twice the size of the previous one, so I guess it was beeing kept in a cool greenhouse. If it was in a cool environment, then it's normal for it to throw a hissy fit if it suddenly finds itself in your hot Houston climate, but don't panick just yet. It should be fine with 70 to 75 F during the day and even 90 F for a few hours every day won't harm it, as long as there is a good temp drop at night. In my greehouse it routinely gets 85 to 95 F during the day at the moment, but at night the temp drops to 55 F and that seems to do the trick. Constantly high temps however will stress it considerably. I know lots of people grow them really well in coastal California, where they also get a bit of heat during the day, but they keep them outside, where the night time temperature drop noticeably and they get a nice bit of mist/fog from the sea at night (San Francisco is particularly good for this). If it stays too warm in your flat at night, try putting it outside in the evening and bring it back inside in the morning ... making sure that it is in a "cricket-free area", of course.
That's the problem, though. The temperature drop in Texas is something like this: 100 F in the day, to 78 F at night. 78 degrees is still hardly "cool", so no matter where I put it it's not going to get a temperature drop that it will notice. Perhaps there's just nothing I can do about it...I may have to move it to my parents house (which is brand new and stays cool) as opposed to it being in my shit ass apartment which traps heat like an oven, even with the air on.
