Let me pick some brains and get back to you. A lot of the 'headstash' strains need special attention to flourish/yield well and SC is certainly one that I'll tuck a couple bushes in the back of my growroom and forget about them while my primary crop does its thing, like I do when I get a wild hair to flower off an OGK.
I actually had SC years ago- I was given cuts by a friend who is now in the penalty box for a bit, and found them to be rather demanding to grow compared to the Affie crosses I'd been running previously.
