I just phased it out after 6-9 months in my perpetual, n I have to say it was an awesome strain. Mine was completely Sensi Star dom(no critical mass traits at all). I know that bc a friend grew Sensi for a cpl yrs ago n i love it n I love the critical SS. Mine had a lemon metallic smell?(sry it's the best way i cld think to describe it). I'm not so good at pin pointing subtle smells, but this was amazing. The buds were rock hard n the frost was out of this world crazy, like insane. It was an above avg yielder n handled nutes very well, mine was done at 49 days but the last 2 rounds I took it to 56 n it bumped up the yield a bit n gave a bit more to the stone. Top quality in everyway, n I only grew out one freebie seed I got. I tell u I'm sold on delicious seeds. Between this n the northern light blue I got, also a freebie, I ran for a cpl rounds last yr, I've got nothin but fire ffrom them. Mine was very N.L. dom n was very frosty n dense too. But I def liked the SS better. Good luck w.u n urs.
