it depends on what you mean by 'good'
if you are talking about growing it then it is good for the amount of THC in the buds.
it also has a high yield per metre squared (up to 550g)
plus the plant is only a 9 week grow indoors (leaving it for 12 weeks will allow the buds to fully mature)
if you are just wanting to know because you are interested in buying some k2 bud, then it would be well worth purchasing as it is some very potent cannabis.
hope this as helped

Weed. K2 is barely researched and could have serious health effects.
As of today, nobody has completed a decent of k2
Yes, you can because K2 is synthetic weed, which makes no THC show up in your system.

the smell. k2 will not smell like weed it'll smell kinda fruity. or at least it does to me
heartburn.angel dustYes
yes
from expericence i can surely tell you no it doesnt
thoughts of suicide, tripping worse then you would with weed. Colors start to blend together, things turn black and white and your resting heart rate rushes 90+ bps. I would not recommend this, weed is safer the k2, but weed is not legal.

No but it can kill you if you do too much or for too long
