I grew White Rhino..it was however back in '96, but no matter it's the original. Since then i have crossed it with God Bud and now have some of that going. Nice buds so far and great growth a perfect mix of the 2 breeds.
I have never grown GWS, but i hear it's pretty good shit, good luck with your grow...i too have yet to harvest any as well, I have 3 flowering, 1 from seed, and 2 that are from my mother.
Keep us updated, i'm interested to see this.
