Critical Jack

Critical Jack Herer's feminized seeds bring together the best qualities of Critical Mass and Jack Herer, creating a genuinely outstanding strain. This remarkable hybrid originated in sunny Spain, where Dinafem Seeds crossed their own Critical with a Jack Herer male from Sensi Seeds. 

The result is a resin-coated, fruity-flavored bud with impressively high yields. By combining Critical’s very early flowering traits with the legendary characteristics of Jack Herer, the breeders produced a homogenous descendant with a slight Sativa dominance.

This unique combination quickly gained mass popularity, earning Critical Jack Herer a household name in the cannabis community, particularly in Europe.

This strain has won numerous prizes, including 1st place in the outdoor category at the Cannabis Cup Thai Maria in 2011 and the Copa Humos del Diablo in Uruguay in 2017.

Growing Information

Our Critical Jack Herer feminized seeds grow into sturdy hybrid plants that abundantly branch out with delicate leaves. She is suitable for novice growers. Her slight Sativa-dominance (60%) is evident in her potent, uplifting, and energetic effects.

Undoubtedly, her most interesting feature is her ability to produce massive outdoor yields with just a very short flowering time! This strain also boasts hardy growth and natural resistance to pests and mold, making it suitable for indoor and outdoor cultivation.

The lime-green, delicate leaves have a narrow, typically Sativa structure and turn purple when temperatures drop. Shiny white trichomes, light brown pistils, and excessive resin production on the conical buds follow.

The best way to achieve optimal results indoors is to use the SOG (Sea of Green) or ScrOG (Screen of Green) method. When space is limited, consider a smaller pot and reduce the vegetative phase. It is also advisable to use a proper carbon filter to mask this variety’s odor levels.

Because Critical Jack Herer feminized remains relatively short and easy to grow, guerrilla growing is also an excellent option. All your plants will be female because our Critical Jack seeds are feminized, omitting the painstaking process of removing males from your crop.

Critical Jack Herer is a novice-friendly, very early-flowering strain. Its flowering period is only 8-9 weeks, and the buds are ready for harvest quickly. On average, they will be ready for harvest from late September to mid-October.

Characteristics

For a Sativa, she remains relatively short. The strain will reach an average height of 70 cm to 100 cm indoors. Outdoors, Critical Jack Herer doesn’t grow much taller, with heights of 80 cm to 140 cm.

Critical Jack Herer produces excellent yields. Under optimum circumstances, this productive plant can yield up to 450-500 grams per m² indoors. But it is outdoors where Critical Jack shines the brightest.

When grown in the Mediterranean or warm temperate climate, this tremendous strain can yield up to 1200 grams per plant! Because of the THC content, which can be as much as 20%, smokers experience a reasonably intense but balanced high.

The 60% Sativa in this weed provides a stimulating effect suitable for various purposes. Excessive cerebral stimulation allows you to remain focused and complete chores seemingly effortlessly. The Indica properties, however, offer a blissful feeling of relaxation.

They are ideal for private conversations in a quiet place. Critical Jack Herer offers a mix of floral and spicy flavors and scents. While the buds smell utterly delicious whole, odor levels rise even further when crumbled.

When crushed, the buds emit a sweet piney fragrance complemented by a lemony floral undertone and incense typically used in churches. Its flavor further complements its sublime aromas. When inhaled, it has a spicy, peppery, bittersweet taste and an acrid lemon aftertaste.

Combined with a touch of fine hardwood and floral hints, it’s no surprise that its delightful flavor is a huge contributor to the success of this strain.
