Critical Jack Autoflower combines the iconic genetics of Critical and Jack Herer for a balanced hybrid that’s perfect for daytime use. Known for its light, energizing buzz, this award-winner leans towards Sativa effects with THC levels around 15%, offering a pleasant high that won’t overwhelm.
Flavor and Aroma That Hit Right
This strain doesn’t hold back on flavor. Each inhale brings peppery spice and a hint of tangy citrus that’s as smooth as it is memorable.
The dense buds pack a terpene-rich profile, with caryophyllene, limonene, and pinene delivering a complex aroma of wood, spice, and citrus. It’s a treat for the senses.
Growing Critical Jack — Ideal for Any Setup
Critical Jack Autoflower is a beginner-friendly strain that’s as easygoing as its effects. Indoors or out, this plant adapts well and shows off natural resistance to pests and mold.
Reaching heights up to 5ft outdoors, it thrives with a bit of room to grow, but using the ScrOG method indoors helps keep its growth manageable while boosting yield.
Expect a flowering time of 8–9 weeks, leading to solid yields of 350g per m² indoors and up to 450g per plant outdoors.
The Buzz Around Critical Jack
Critical Jack’s genetics deliver a well-balanced high that’s both uplifting and mellow. Think of it like your morning espresso but with a smoother finish, keeping you alert without overdoing it.
With its memorable aroma, easy cultivation, and smooth, energizing effects, Critical Jack Autoflower is a favorite for those who want a fuss-free, standout strain in their grow lineup.
