Compact mostly dark green buds, smell is not really clear or heavily present. The taste is hard to define as well, a bit earthy and woody, leaving a burning sensation at the top of the throat, wich is also the only real spot for cottonmouth. The effects are 'just chill', they're not heavy or overpowering, I can easily have two spliffs of this and not feel paranoid or completely couchlocked. Which is typical for this strain. I consider it a true hybrid. The body has a slight tingling sensation and the mind is relaxed but not too clouded. A bit of time dostortion sets in later on, but leaves you capable of getting stuff done. Thus K2 might be an excellent daytime medication for some, but since I use recreationally I'm not sure it would kill pain or relax muscles as much as you need. At higher doses slight CEV's, and it does help you relax your mind to fall asleep, instead of punching you out like stronger types do. It's the balance, more than the strength of the effects and my personal preference that make me rate this 4 stars.
