Critical Jack Autoflowering Seeds

Critical Jack Autoflowering Seeds combine Critical-family genetics with Jack/Haze-type ancestry and an automatic flowering trait, producing a medium-sized, sativa-leaning auto with strong branching, noticeable stretch, resinous flowers, and a bright citrus-pine aroma. Commercial Critical Jack autos are not all built from exactly the same breeding formula, so the most reliable description is a Critical × Jack/Haze auto rather than one universally fixed pedigree.

• Lineage: Critical-family × Jack/Haze-family genetics × autoflowering ancestry
• Growth type: Sativa-leaning autoflower
• Plant structure: Medium to medium-tall for an auto, with a strong central stem and symmetrical side branching
• Stretch: Moderate during the transition into bloom
• Indoor seed-to-harvest: Typically about 9–10 weeks from sprouting
• Outdoor seed-to-harvest: Typically about 9–11 weeks from sprouting; harvest depends on sowing date
• Flower structure: Elongated to moderately dense flowers with good calyx development
• Resin production: Moderate to high
• Colour: Bright to medium green with orange pistils and a frosted finish
• Aroma: Lemon, citrus peel, pine, herbs, wood, and light spice
• Best suited for: Growers wanting Critical-style productivity with Jack/Haze aroma in a fixed, relatively quick cycle

Critical Jack Auto usually develops more vertical energy than compact Kush-style autos, so gentle low-stress training can help distribute growth before flowering accelerates. The automatic life cycle limits recovery time, making light canopy shaping more useful than repeated heavy pruning.

Indoors, a practical full-cycle target is approximately 63–70 days from sprouting. Flowers typically lengthen first and then gain density and resin through the second half of the cycle. Because the canopy can become fairly branchy, good airflow through the middle of the plant is useful as the flowers mature.

Outdoors, harvest timing depends on planting date rather than autumn day length. Under favourable conditions, plants generally finish in about 9–11 weeks from sprouting. This makes the cultivar useful where a full-season Critical Jack photoperiod plant would finish too late or grow too large for the available season.

The aromatic profile commonly combines bright lemon and citrus with pine, herbal, woody, and lightly spicy notes. Critical Jack Autoflowering Seeds are best suited to growers looking for a medium-sized auto with vigorous branching, a roughly ten-week life cycle, and a clear citrus-pine character.
