The Caps Lock, because it seems to be stuck.
As for the marijuana...
I'm not sure if I'd say it's the best I've ever grown, but it does fit what you're looking for:
The often overlooked Afghan Kush Ryder is a stinky little beast to grow, but has THC at 22%+, will stone you out (Indica 100%), then linger on and on.
It is pretty short and a very fast grower. Like 45-55 days from seed, fast. You can expect to pull about an Oz off a single plant under good growing conditions, give or take. CFL friendly, too. The only drawback is the smell, but an Ona block helped a lot. That said, I would not grow it again without a tent and good filter.
