judging by the size of that cfl in the pic, it doesnt look like a huge plant.
the key imo is that you know they aren't suspicious of you, its a routine inspection that will take 2 minutes. You can easily keep it in your apartment, simply cover it with whatever you think is best, and place in an area away from anything they may be inspecting(closet should be fine). clear out your grow room, and do some baking/smoke a cig as mentioned, make sure it is strong smelling. when they knock spray febreze where your plant is.
I can totally understand why you are nervous, but I think youll be fine man. Worst case they get a quick wiff, theyd likely figure you have some weed in the apt at worst case, and legally they aren't allowed to touch your personal belongings(im sure some landlords ignore this). Would be different if you hadnt seen the notes on all your neighbors doors tho.
Good Luck
