Seb's take
RS-11 cut crossed with Auto Z F5, a mostly-Sativa auto built on vigour, resin density and an unmistakable citrus punch. Sour lime and fruit on the nose; uplifting, happy, energetic on the exhale, mentally bright while staying grounded in the body. Twenty-nine per cent THC — she lives up to the name.
Where it comes from
Fast Buds blended the RS-11 cut with Auto Z F5 to make this one, a mostly-sativa autoflower at 65% to 35% indica. The RS-11 cut is prized for its resin and its unmistakable citrus punch; the Auto Z F5 supplies the timing and the sweet backbone. The result shines through vigour, resin density and that lime-forward brightness. Twenty-nine per cent THC by the record — she lives up to the name Z-Up on more than one count.
Nose & flavour
Sour and lime lead, crisp and sharp, with fruit softening the finish — a lime-forward aroma that manages to feel crisp and sweet at the same time. The buds form tight clusters dusted in frost, and they release that citrus punch readily. It is a bright, zesty nose with just enough sweetness to keep the sourness from turning austere. Fresh, sharp, and unmistakably citrus-led.
The high
Uplifting, happy, energetic on the exhale — upbeat, clean and steady, offering enough mental lift for creative tasks while keeping the body grounded. It follows the brightness of the nose: a clear, momentum-forward experience that engages the mind without unmooring the body. A daytime sort of high, sociable and productive with it. THC sits at 29%, so the lift is bright but by no means light — pace yourself accordingly.
Growing it
A medium auto, 70 to 120cm, vigorous and resin-dense. Flowering runs 56 to 63 days, around eight to nine weeks from seed at a standard auto pace, yielding a solid 458 to 610 g/m². The tight, frost-dusted clusters mean genuine stickiness, so keep your scissors clean as you trim. A robust, resinous plant that rewards a grower with good light. THC 29% — very strong, a sipping strain rather than a session one — with 1% CBD alongside.
