Picking a pure sativa for a first ever grow is a common source of early frustration. The long flowering time, the stretch, and the sensitivity to overfeeding all punish beginner mistakes that a forgiving indica hybrid would shrug off. That said, the beginner recommendations on https://hazesativaseeds.com (https://hazesativaseeds.com) do include a couple of sativa dominant lines with shorter flowering windows that are realistic for a first attempt. Starting there and moving to the longer equatorial genetics on the second or third run is the path most experienced growers suggest.
