Critical Lemon FAST blends Critical Lemon with Auto Critical to deliver a quick-finishing, sativa-leaning photoperiod. It offers bright citrus character, solid structure, and dependable yields. Ideal for beginners and busy growers who want speed without giving up quality.
This fast-flowering Feminized variety keeps the recognizable Critical backbone with a fresh lemon twist. Expect a short bloom cycle, lively citrus aromatics, and high production. It suits indoor tents and short outdoor seasons where timing matters.
This recognizable cultivar pairs the vigor and yield of Critical lines with a zesty lemon profile. It grows with balanced branching and a medium height, forming dense, lime-green buds that sparkle with resin. Indoors, it stays tidy and responds well to simple training. Outdoors, it finishes early, often before fall weather turns. Expect a consistent citrus-herbal nose across most plants, with sweetness up front and a clean finish. Colors lean bright green with amber hairs; cooler nights can tease faint lavender tones in some phenotypes. For new growers, the ease of feeding and quick timing make it friendly. For experienced growers, the speed-to-yield ratio is the draw.

Advanced Seeds paired Critical Lemon with Auto Critical to shorten bloom while preserving photoperiod control. Critical Lemon brings classic Critical yield and sturdy branching, with a bright citrus top note. Auto Critical contributes speed, uniformity, and compact internodes without pushing the plant fully auto. The result is an early-finishing, sativa-leaning hybrid that stays manageable indoors and wraps up quickly outdoors.
Expect strong initial vigor and easy training. Buds stack along laterals, forming dense, resin-rich colas. The cross aims for stability in aroma and structure, with most plants sharing the same lemon-sweet signature. Resin coverage is generous, making trim work sticky and rewards good drying and curing. The shortened bloom (often 6–8 weeks) is the key advantage, reducing risk in wet or cool regions while keeping yield high for the timeframe.
The flavor mirrors the nose: bright lemon up front, sweet citrus through the mid, and a tidy herbal finish. It is easy to enjoy and easy to recognize in a mixed jar. Growers like its room-filling citrus during late flower; consumers appreciate the clean, lively taste.

Body Effects
Plants reach medium height with a sturdy central stem and well-spaced laterals. Internodes stay moderate, supporting dense, lime-green buds with bright orange pistils and a frosty coat. Aroma intensity ramps up after week four of bloom. Many plants finish with a glossy, resin-rich sheen; cooler nights may show light lavender edges.

Yield and Cultivation Notes
Expect a high-yield class for the timeframe, with medium-high bud density and strong citrus terpenes. It suits newer growers due to simple feeding and a short, forgiving bloom. Experienced growers can push canopy management for bigger top colas.
“First-time indoor grower here. Four plants in a 3x3, SCROG, finished in 7 weeks of flower. Sticky trim, strong lemon, and the buds stayed dense even after dry. Easy feeding, no drama.”
“Intermediate outdoor grower in a cool climate. These wrapped up by early September, which saved me from fall storms. Two phenos: one super lemon, one heavier and sweet. Both yielded great for the time.”
Fast bloom, bright lemon aroma, and strong yields make this Feminized photoperiod a smart pick for tight schedules and small tents. Get the timing advantage without sacrificing quality. Order now and plan your next run with confidence.
Is this strain suitable for beginners?
Yes. It has a short bloom, steady vigor, and simple feeding needs. Basic training opens the canopy, and it handles minor mistakes well. Keep airflow strong, watch humidity in late flower, and you’ll be rewarded with dense, aromatic buds.
How long does flowering take indoors?
Most gardens finish between 6 and 8 weeks after the flip. The Critical-leaning phenotype can be ready on the early end. Check trichomes to confirm your preferred maturity, and plan your flush accordingly for best flavor.
Does it grow tall or stay compact?
It tends to stay medium height with balanced branching. A lemon-leaning pheno may stretch a bit more, but LST or a simple screen keeps the canopy even. Expect manageable plants that suit tents and modest ceiling heights.
What kind of aroma should I expect?
Plan on lemon zest, sweet citrus, and a clean herbal finish. The scent builds in late flower and can be strong in a closed space. Good filtration is recommended indoors, especially during weeks five through harvest and while trimming.
How are the yields for the timeline?
Yields are high for a fast-finishing photoperiod. Dense tops stack along the branches when the canopy is well lit. Keep nutrition steady and airflow consistent to help the plant fill out without microclimates or excess humidity.
Is this an autoflower or photoperiod?
It is a photoperiod “FAST” strain. The Auto Critical parent shortens flowering, but plants still require a 12/12 light cycle to bloom. You get faster finish times without losing control over veg length and training.
Are these seeds Feminized?
Yes, they are Feminized. This means nearly all plants grown from seed will be female. It helps simplify planning for small spaces and maximizes canopy use without the need to identify and remove males.
How stable is the phenotype expression?
Most plants show a consistent citrus-forward profile and medium structure. You may see one of two main expressions: a slightly taller lemon-leaning pheno, or a stockier Critical type. Both share strong resin, quick finish, and dependable performance.
