Alright! A gsc is showing roots!! And the skywalkers roots a bit faster
NorCal- I'm with prop on that, looks identical to the mutated cherry pie I had. Absolutely love the way she grows. I've got some cookies in beer cups now.
AFAIK...There are no different phenos of GSC, but there are fakes.
Genetic drift can happen though, and depending on when the cut was taken, or even where on the plant it was take can cause slight mutations. Happened to my SSK after I took cuts at the start of flower.
+++Oh and Grindhouse DOES NOT have the real GSC.
