Seb's take
This autoflowering Permanent Marker took first place for Best Flower at the Leafly 2023 Awards, and at 32-34% THC it leaves an impression accordingly. Candy and floral sweetness on the nose; the high is euphoric and creative before the body eases into something smoother. Fast, scheduled, and hard to overlook — the name is apt.
Where it comes from
World Wide Cultivars have taken the photoperiod Permanent Marker and married it to Ruderalis, producing an autoflowering version that keeps the parent's reputation intact. And that reputation is considerable, the balanced hybrid took first place for Best Flower at the 2023 Leafly Awards, which is not a ribbon handed out lightly. The Ruderalis contribution is purely practical, adding the automatic timing without diluting the character. The name, for once, suits the product: this is a strain that leaves a mark and does not rub out.
Nose & flavour
The nose is sweet and floral, closer to confectionery than to fuel, a candy-floral impression that gives the smoke a boutique feel rather than a heavy one. There's a brightness to it that matches the effect, and none of the diesel or skunk one might brace for. A polished, modern profile, and pleasant company from grinder to glass.
The high
The effect leans creative and euphoric, a bright, happy lift that keeps the mind engaged before the body gradually settles into something smoother. At a stated 32 to 34 percent THC this is emphatically not a beginner's afternoon, a sipping strain, not a session one, but the character stays cheerful rather than flattening. Approach as you would a staircase in the dark, and it rewards the caution.
Growing it
As an autoflower the schedule does the thinking for you, flowering runs 56 to 70 days from a plant that reaches around 150cm, tall for the format and worth the headroom. Yields land between 336 and 488 g/m², solid for an auto of this potency. The autoflowering habit makes it easier to time than its photoperiod relatives, a genuine convenience for anyone juggling a busy calendar. Resin coverage befits the THC, so keep your trimming scissors clean and close to hand.
