I have grown in my garage before and the flowering smell, at the peak two weeks, filled my house. Up to you :)
Tents can help contain this smell with the assistance of carbon filters. Tents also reduce the size of the space you are temperature/humidity controlling (if your office is outside of ideal parameters).
With regard to the window, I am confused, I see in your diary you have a grow light. If you are running the light, the two combined would give you your total Daily Light Integral (DLI, which is the total light intensity your plant receives in 24 hours). Ideal DLI is outlined in this article and this company also offers a free app to measure it (you will need to wrap printer paper around your phone's camera to act as a difuser per their instructions).

Also, not sure if I am seeing the picture right, but if your cotelydon (first) leaves are right at the surface (or one maybe under), you may have planted your seed a bit deep and you may want to clear some of the soil away from those leaves.
Good luck and happy growing!
