Critical Mass Fast blends the hefty production of Critical Mass with the accelerated finish of Auto Critical. Expect an indica-leaning, quick-blooming cultivar with dense, aromatic buds. It suits beginners who want a reliable, early harvest and growers seeking efficient turnaround.
This fast version keeps the bulky bud structure while trimming weeks off bloom. Flowering wraps in 6–8 weeks, delivering sweet, earthy-citrus aromas with a gentle skunky edge. Ideal for small spaces, short seasons, or anyone prioritizing speed without sacrificing yield.
This strain is recognizable for its compact, sturdy frame and oversized colas that stack early and finish firm. Indoors, it responds well to light training and basic canopy management. Outdoors, the short flowering window lets it finish before autumn weather complicates late runs. Expect consistent nodes, vigorous early growth, and a predictable stretch that stays manageable in tents.
Aromas lean sweet and earthy with citrus peel and a faint skunk thread, becoming louder in the last three weeks. Buds cure to rich greens with bright orange pistils; cool nights may tease out subtle purples. Phenotypic variation is modest, with most plants tracking a uniform structure and finish time, making planning and scheduling straightforward for new and experienced growers.

The backbone here is Critical Mass, known for thick flower clusters, sturdy branching, and generous yields derived from Afghani and Skunk roots. Auto Critical contributes speed genes and early resin push, used selectively to shorten bloom while keeping the photoperiod habit intact. The result is a fast-finishing, indica-leaning plant with dependable structure and strong flower density.
Advanced Seeds aimed for practical performance: predictable height, reduced flowering time, and a terpene profile that balances sweetness with earthy citrus. Plants show good apical dominance with cooperative lateral growth, making canopy control simple. Resin production begins early and stacks heavily by week four, supporting both flower and extract goals. Stability is notable, with most seeds expressing similar internode spacing, stretch, and finish window.
On the palate, citrus and sweetness lead, grounded by earthy, woodsy undertones. The balanced profile appeals to everyday consumers and growers who value jars that smell inviting without overwhelming the room. It finishes smooth, making it a steady, reliable choice for daily enjoyment.
Plants run medium height with a stout central cola and supportive side branches. Leaves are broad and dark to mid-green. Buds are chunky, tightly packed, and glossed with a generous trichome coat. Aroma intensifies late, especially after light leaf removal and improved airflow. Occasional cool-night purpling may show on sugar leaves and calyx tips.
Expect a high-yield class with very dense buds and strong, sweet-citrus-earth terpenes. Resin output makes trim worthwhile for extracts. Novice growers should plan simple training and reliable support. Keep humidity in check during late bloom to preserve top-end quality.
“First indoor grower here. These Feminized seeds were easy to manage in a 2x4 tent. Finished in seven weeks with big, dense colas. Sweet citrus smell came on strong near the end. Solid yield without complicated techniques.”
“Intermediate outdoor gardener. Short season, coastal climate. Plants stayed compact and finished before the first rains. Earthy-sweet flavor, great bag appeal, and sticky trim for hash. Will run again for the speed alone.”
Get a fast-flowering, high-yield indica-leaner that fits tight schedules and smaller spaces. Feminized seeds simplify selection, while the sweet earthy-citrus profile keeps jars interesting. If you value speed, density, and consistency, add this to your rotation and plan an early finish.
Yes. It has a manageable structure, short bloom, and consistent behavior, which reduces variables for new growers. Basic training, steady nutrition, and good airflow are enough to reach strong results without advanced techniques.
Most plants finish in 6–8 weeks from the start of bloom indoors. Watch trichomes from day 40 onward and adjust harvest time to your preferred maturity for flavor and effect.
Expect a sweet, earthy base with citrus zest and a mild skunk thread. The profile is inviting and balanced, becoming more expressive as the buds cure for 10–14 days.
Plants stay medium height with a modest stretch, typically suited to 4–6 feet of total tent height. Light training and a trellis help maintain an even canopy and support heavy colas.
It sits in the high-yield class with dense, weighty buds. Proper support, consistent feeding, and controlled humidity in late flower help maximize output and preserve quality.
Yes. Phenotypic spread is modest, with most seeds showing similar structure, finish time, and terpene range. You can plan training and harvest windows with confidence.
Yes. They are Feminized photoperiod seeds bred for a shorter flowering phase. Plants still require a 12/12 light cycle to bloom indoors.
Both. Indoors, it stays compact and quick. Outdoors, the early finish helps avoid fall moisture. Choose based on your space and local climate.
LST, topping once or twice, and SCROG are effective. Focus on opening the canopy, supporting heavy branches, and keeping airflow moving through dense flower sites.
In suitable climates, expect late August to mid-September. Local weather and latitude matter, so monitor pistils and trichomes to fine-tune your cut date.
