There are so many named and unnamed genetics, it is not even funny.
Everyone has their flavors, but if you are looking for an extreme head high, most all strains will be good, that has Haze dominance in their genetics.
As far as what I have tried " wich is my share of strains, but definately have not tried them all of course, " I settled on a Haze dominant Strain called " Carnival from ministryofcannbis. "
As far as the European strains are concerned, this is one great type.
It has up to 25% THC if grown correctly and best harvested around 50/50 cloudy/amber trichomes.
Loves Molasses if grown organic and has a very smooth and sweet taste.......the head high is something to be tried at least once......very creative and trippy at the same time and if you honestly go past the fourth toke, even a seasoned veteran will have a hard time staying motivated, but used correctly, will keep you on your toes and blazing in your mind, for longer than anything I have tried as far as smoking it.
Now, if you want a head high and body energy like no other.......try your luck getting a pure female grown out of some Mexican Cannabis or " bagseed. "
Not enough credit is given to bagseed, but if you are patient and get a nice pure female sativa and grow it out, you will have that in wich you really want...........That Bob Marley Blazin Smile,LOL.
