I have some experience with some of Subcools stuff. I've growN Jilly Bean, Agent Orange, Space Bomb, Chernobyl, Vortex and JTR. Subcool has amazing genetics, some of the best out there IMO, nad yes, they are all sativa dominate pretty much. But the confusion here is coming in because Pops is lookin' for a Sativa that finishes early (hard to find), Basically jhew wants a pure sativa with just enough afghan (if any) to make it quicker. Subcools strains are sativa dom hybrids, but more along the lines of a 50/50 "type" cross, that has big dense buds and so forth, and an "up type" high. Blue Dream, Green Crack, SSH, they all fit that same bill, which is NOT what Pops is lookin' for. Most peoiple nowdays, don't even know what a real sativa is, cause there is hardly any around any more. They are all hybrids, with the Afghan genetics showing up in them, other than flowering time.
Yes Subcool has some of the best sativa dom hybrids around for sure, buy they're not what your lookin' for Pops.
