Lemon AK Auto is Fast Buds’ citrus-soaked take on the classic AK-47. To build it, Fast Buds crossed its Original AK Auto with Jack Herer Auto, creating an F3 feminized polyhybrid selected for vigor, lemony terpenes, and strong resin output. The aim was to soften the familiar AK profile with fresh lemon zest while keeping its potency and productivity.
The result is a 75% Sativa / 25% Indica autoflower rated at up to 24% THC with CBD under 1%. Fast Buds lists it in the XXL size class at 70-130 cm (28-51 in), and it is one of the more productive autos around: 500-650 g/m² (1.6-2.1 oz/ft²) indoors and 60-250 g (2-9 oz) per plant outdoors.
Because it is an autoflower, no change in light schedule is needed. Keep it under 18/6 or 20/4 the whole way and harvest arrives 9-10 weeks after sprouting.
Early growth is bushy and stout, then the bloom phase piles on thick, frosty flowers around a dominant central cola. Low maintenance needs and strong pest resistance make it a friendly pick for beginners, indoors or out.
Lemon Zest, Skunk, and a Balanced High
The flavor blends earthy AK character with sharp lemon zest and a peppery kick. Skunky depth and a sweet, pie-like note fill in the middle, creating an assertive aroma that carries straight through into extracts. Thick trichome coverage makes it well suited for terpene-rich oils with a lively citrus profile.
The effect is a finely balanced Sativa hybrid: an uplifting, fruity-tasting high that sparks ideas and conversation, with enough body presence to keep you grounded. Reported effects are led by happy and energetic, with relaxed and creative close behind, and a fair share of people describe feeling talkative. It shines during creative sessions and social events.
Growing Lemon AK Auto
Lemon AK Auto pays back strong lighting and ample room with generous harvests and even resin coverage. Its stout frame suits growers with limited room, yet the plant can push volume when given a large final pot and strong light. Light LST helps the side branches catch up with the main cola.
It handles indoor tents, outdoor gardens, greenhouses, and mixed-light rooms, and its resistance to pests keeps outdoor runs low-stakes for newer growers.
