My Desk Location: will or will not work?

[REEFSTOCK]

First post here.

I am no stranger to addictive hobbies, infact I turned one into my life's carrier. So, taking things slow, researching, doing things right the first time are all in my blood.

I'm interested in orchids and am excited to go find them out in my limited spare time. Time... ah the thing we can't buy more of I know orchids need some special attention. At this point in my life the only place I could reliably give it is at my work desk. Here is the issue:

Humidity ~ 30-40 (guessing, haven't checked in a while)
9am-10PM 74-78F
10PM - 8 AM 78-84F

I've got every kind of light available to me (well perhaps not natural sun), and I run many things on a reverse daylight cycle. Still...
Should I put growing orchids on hold till I can find another environment?
I'm not interested in killing something just to see if it works, if anyone has any info or experience with such temperatures I would appreciate a post.

Thanks,
Fritz
