HSO chem dawg (chem 91) was the easiest plant I've ever grown. In not sure what kinda buzz your looking for or flowering time but mine took 9 weeks and its a very potent, alert and happy buzz. Kinda like herbal prozac, gives lots of focus great for house work. Heavy feeder, not picky with nutes.
I grew mine in 7 gallons of Dr earth home grown from home depot, and top dressed with biolive from Amazon.com
