Seb's take
Totally Alpha OG, Haze IBL and Zalla combine under a breeder who started as a trimmer before founding his own seedbank — the OG backbone shows in the therapeutic reputation that followed. Wood, sweetness and spice on the nose; the effect is sleepy, medicinal, happy, at a reported 30% THC that asks for a staircase-in-the-dark sort of respect.
Where it comes from
Totally Alpha OG, Haze IBL and Zalla combined, and the record is more interested in the breeder than the pedigree, telling of a man who came up from trimmer to the founder of his own seedbank. That arc shows in the work: the OG family forms the backbone, the Haze lends the cerebral reach, and Zalla rounds the cross out. AlphaFem have built it, by their own account, for two things above all, potency and ease of growing. At a reported 30% THC, the first is not in doubt.
Nose & flavour
Wood and spice with a sweetness threaded through, a warm, resinous nose that owes as much to the OG backbone as to anything else in the cross. The spice gives it edge; the sweetness keeps it approachable. It is not a loud aroma so much as a deep one, the sort that fills a jar slowly and rewards a patient nose.
The high
Sleepy and happy is the honest account of it, an evening disposition that settles the body and quiets the day. At a reported 30% THC, with a notable 2% CBD alongside, this is emphatically not a plant to meet casually: approach as you would a staircase in the dark, one careful step at a time. A sipping strain, and not a session one.
Growing it
Manageable for all her strength: she holds to around 120cm, a medium stature that most rooms take without complaint. Flowering runs 49 to 63 days, and the wide window is worth watching by eye, since the trichomes will tell you more than the calendar on a plant carrying this much resin. The harvest is generous at 600g/m². Feminized seed keeps the pack clean, and the breeder's stated aim of easy cultivation appears to hold, a heavyweight in the jar, but a civil one in the tent.
