Seb's take
Earthy pine and sweet wood, pungent enough to announce itself before the jar opens. Whatever the truth behind G13's shadowy, secret-lab origin story, the high is honest enough — euphoric, uplifted, sleepy by the end. Strong and high-yielding, rather more memorable than its own cover story.
Where it comes from
Herbies Seeds built this by crossing G13, the Afghan indica of shadowy repute, with Ruderalis to set its own clock. The history, as the record freely admits, is shrouded in mystery, an urban myth popularised by the film American Beauty holding that G13 was an experimental hybrid developed in secret government labs back in the sixties. Whatever the truth of that, the plant itself is no myth: strong, generous, and rather more memorable than its own cover story.
Nose & flavour
Earthy and woody at the core, with pine lending a resinous edge and a sweet thread running beneath. It is a classic, grounded profile rather than a flashy one, pungent enough to announce itself before the jar is properly open. The Afghan heritage shows in that earthy, resinous character, fresh and memorable in the record's own estimation, and true to it.
The high
A super-potent, euphoric experience, in the record's words, running happy and uplifted up top before settling toward sleepy by the end. It lifts the mood first and lowers the body after, an even, well-mannered arc. For all the intrigue attached to its name, the high itself is honest and straightforward, which is more than can be said for the secret-lab story it comes wrapped in.
Growing it
An autoflower finishing in 70 to 84 days, reaching 80 to roughly 120cm, so a manageable stature for most spaces. She grows strong and yields more than well, 488 to 610 g/m², which is a solid return for an auto. At 23 to 25% THC with 2% CBD she carries genuine strength alongside a touch of balance. A robust, dependable plant, and a good deal more real than the mythology that trails behind her name.
