Id have to agree with evans here, as I pretty much purchased seeds with the same idea in mind.
I dont think there is really 1 strain that does it all. Even if there is it would be like a search for the grail. Youre better off growing 2 strains.
My choice, for example, was Super Silver Haze for day time smoke, and Papaya for night time.
Some other good suggestions would be (from what im told):
Day time:
-Bangi Haze (ACE). Ive heard great things about this one, and its very aesthetically pleasing to boot.
-SSH (Mr Nice). Can you really argue with back-to-back-to-back CanCup winning genetics?
-Kali Mist (Serious)... This one take a bit longer to flower but from what I hear is WELL worth it. Supposed to have a creative up high. Great for listening to music and such. This is actually at the top of my list, I would have grabbed it but didnt want such a late bloomer for first grow.. lots of time to mess up hehe.
-Strawberry cough (Dutch Passion) As evans said...
-Northern Lights #5 x Haze (Sensi) Legendary from what I hear... plus from the pics Ive seen, holy hell she's a sexy bloomer.
Night time:
-Papaya (Nirvana) Supposed to be very mellow, lethargic almost narcotic stone. Also supposed to smell/taste of mango
-Hash Plant (Sensi) Highly resinous. Deep stone.
-White Russian(serious) Also highly resinous. (Any white strain is)
-Violator Kush (Barneys)
-Medicine Man (Mr Nice) if it means anything to you... this strain comes with a warning

. They say to be careful smoking it as even experienced smokers have trouble finishing a joint.
Hope this helps. Your best bet is just to jump on some seed sites and start reading away. Also Ed Rosenthal's(sp?) Big Book of Buds is pretty awesome. Tells you all about the strain and who breeds them.
