Seb's take
Autoflowering Sour Diesel, bred for speed and yield rather than subtlety. Vanilla and sour cream on the nose, oddly gentle for something so Sativa-dominant; the cerebral ascent gives way to calm body relaxation and a sudden interest in the contents of the fridge. Cruising, not racing.
Where it comes from
An autoflowering take on the legendary Sour Diesel, built from California Sour Diesel, its auto counterpart, and OG Kush Auto — Humboldt Seed Company bred it plainly for performance: quick flowering, heavy yield, and unmistakable Cali character. Eighty per cent sativa, so the Diesel lineage leads, with the OG auto supplying the format. A working plant with a famous surname.
Nose & flavour
Vanilla and sour cream at the front — oddly gentle and smooth for something so Sativa-dominant, with a creamy roundness softening the expected diesel bite. A more inviting nose than the Sour Diesel name might lead you to brace for. Characterful without being harsh.
The high
A ripping cerebral lift to open, which then dissolves into calming body relaxation — sleepy at the end, and with a reliable appetite arriving along the way. Cruising rather than racing, for all the sativa dominance. It carries you through an evening rather than charging at it.
Growing it
Autoflowering and bred for the numbers — quick to flower at 70 days, with the record promising a heavy yield though no figure to hang it on. Potency sits at a solid 21%. No height is listed; a Sativa-dominant auto of this sort will stretch more than most, so leave headroom despite the compact format. A fast, generous grow with genuine West Coast character — potent, resinous, and earning its reputation.
