C99, sativa high in a 7.5 week plant that doesn't stretch. It's a bit racey and paranoid inducing for some people (I don't have that reaction to it), but many sativas do that to people. Fruity taste (mango/pineapple). Highly recommended. Apollo is similar but a bit more mellow, more lemony and a bit higher yield.
Sour diesel is real popular right now, rez at Seedsdirect has been working with some back crosses with the legendary ESCD clone. Some guy at seedbay has trainwreckS1. Silver haze is good as well. I like Mother's Finest from sensi, but the phenos are all over the place, the JH pheno is really good but you'll have to grow out a good number to find the phenos you want.
