This plant is awesome. It’s super fruity tasting and the high is both uplifting and relaxing. I am pretty happy with the end results.

I have grow these genetics before and they are fantastic. They give a nice hybrid high of relaxation and a bit of uplifting feelings. One plant was fairly fruity tasting and the other has a skunkish flavour to it.

Hi folks.
I'm having some of your strains in my tent these days but my buddy mixed up the seeds so I don't know what's what:sweat_smile:. Maybe one of you checks by the diary some time and can give me an idea what could be what. 4 Strains in 3 Plants are in the jeopardy:grin::sweat_smile:.

@occultgreen420, wrong Humboldt. You’re thinking of Humboldt Seed Company. This is HSO.
