Anyone grown any critcal mass?

does it really have huge yields and a really good high?

big sized buds, better than average yield, but i think you lose potency when you have the bigger buds. it was really weak. it seems anybody who has experience either growing it or smoking it says the same. i grew it once and never will agian. if you want big yield and potency, ive had good luck with blueberry punch lately, even though its not known as a big yielder.
