What's Critical +?
I can only speak from my research, but I think it really depends what you want out of it. From what I've seen, if you are looking for a quick growing, high yielding plant with a couch-locking mediocre stone, then Kritikal is the plant for you. Change any of those varialbes and you should look for another strain.
It was mentioned in another thread, but LSD by Barney's is supposed to be fairly equivalent to Kritikal in terms of yield, but apparently the high is much more pleasant and appealing. IDK. LSD is on my list, but haven't gotten to it.
Friends grew a pack of LSD, it's just another boring skunk cross just like the critical. It's not trippy at all, just a boring ass couch lock. I honestly hated all things skunk because my only experiences had been shitty dutch crosses that made you slow and dumb and built your tolerances fast. Then I realized that some of my favourite clear headed strains had skunk in them.
