I'm currently growing Crimson Crush and as a matter of fact I'm about to yank it tonight. I will post some pics and a review on the GGG thread some time soon.
I can't speak to how CC will do outdoors, but it certainly looks the part indoors. The pheno that I'm finishing up right now is the 7 week variety. I'm on day 51, but it looked pretty much done at day 49. Crystals started developing pretty early, around day 21. It's a very fruity smelling strain and it has a strong odor. Brush up against the stalk or a bud and you will reek. I haven't smoked it yet so I don't know if the smell will translate to taste. The one possible complaint I have is that it's not very dense, but I have yet to grow a GGG strain that is dense. We'll see though. The yield should still be decent in spite of the lack of density. Just to clarify, the buds are not airy, but they're by no means rock hard either.
The strain is also quite vigorous and easy to clone. It stretches quite a bit as well so you might want to force it to flower at 18" unless you don't mind having 5' indoor plants.
I have also grown Sugartown Express and Grape Puff from GGG, but I wasn't impressed with either of those.
