Critical Jack Feminized Seeds
Price range: $65.00 through $255.00
Critical Jack is a feminized hybrid that merges the high-yielding strength of Critical Mass with the citrus-spice aroma and vigor of Jack Herer. Fast-flowering and productive, it delivers dense, resinous buds with a sharp lemon-pine scent and classic sativa energy.
This hybrid combines two elite lineages into a well-balanced, garden-ready variety. Critical brings short flowering times and heavy colas, while Jack Herer adds structure, aroma, and sativa resilience. Plants grow tall and vigorous, forming long branches packed with trichome-coated buds. The flowers are bright green with orange pistils and a frosty finish, giving them strong bag appeal. The fragrance is bold and layered—citrus peel, pine, and spice mixed with a hint of sweetness. Growers appreciate Critical Jack for its stability, speed, and strong yields, both indoors and outdoors.
Sow Critical Jack feminized seeds indoors 4–6 weeks before transplanting outdoors, or directly into soil in regions with warm, sunny seasons. Plants typically reach 150–200 cm and respond well to topping, pruning, and training to manage stretch and create even canopies. Flowering completes in 9–10 weeks indoors, with outdoor harvests ready by mid-October. Thriving in full sun and fertile, well-drained soil, this hybrid produces large, aromatic, and resin-rich harvests.
