STRAIN DESCRIPTION
Critical Jack Fem Strain Review
After waking up, do you often feel tired, lifeless, and downright uninspired? If so, Critical Jack Fem is what you need to start your day right. Featuring up to 55% Sativa makeup, it descends from two highly illustrious strains, Critical Plus and Jack Herer. This hybrid is revered for its long-lasting euphoric and mind-focused effects - strong enough to get you going but mild enough to keep you functional. More than that, it's also ideal for people suffering from stress, anxiety, and chronic pain.

Critical Jack feminized seeds are perfect for beginners. They're fast-growing and produce insanely massive yields. Plus, they have an increased tolerance to mold and pests, which means that they could be grown outside without any issues.


In terms of physical appearance, the plants are unmistakably Sativa. They're incredibly tall and slender and features sparse, lime-colored foliage. Meanwhile, the buds are cone-shaped and come in a light green shade. On the surface, you'll find a smattering of pale brown pistils and a generous layer of resin. To increase the nugs' bag appeal, try exposing them to lower night-time temperatures. Doing so will trigger the purple pigments called anthocyanins, adding a pop of color to the otherwise monochromatic flowers.

For a Sativa-heavy hybrid, Critical Jack has a relatively short flowering period. Indoors, the plants typically need 8 to 9 weeks to finish budding. If raised outdoors, it means that you could gather the colas anywhere between late September to early October.


To determine if the plants are ready for collection, keep an eye on the trichomes. They're transparent and glass-like at first - a sign that they're still developing. Once the resin production is at its peak, the glands will become cloudy like plastic. When this happens, it's time to get down to business. You could also wait until 70 to 90% of the pistils have darkened, which indicates that the plants have already attained peak THC concentration. But generally, monitoring the trichome color is a more reliable approach.

This hybrid is well-suited for indoor cultivation, although certain adjustments need to be made. Since it's mostly Sativa, the plants tend to be towering. If you have limited space, you'll have to train the plants to restrict their vertical growth. Furthermore, you might want to consider shortening the vegging phase. To increase the yields and manage plant growth, the Screen of Green (SCROG) method is highly recommended. If all goes well, you can expect around 21.2 ounces (600 grams) per square meter.
Critical Jack is best grown outdoors in a Mediterranean climate. If the plants have access to plenty of space and sunlight, they can reach up to a whopping 300 cm (10 feet) in height. Healthy, vigorous growth, in turn, translates to more massive yields. But if you prefer to be discreet, this could be an issue. Make sure to train the crops as needed to keep them from growing too tall. This weed could generate as much as 42 ounces (1200 grams) of gooey nugs per plant under excellent environmental conditions.

Like Jack Herer, Critical Jack is also an intensely therapeutic strain and is fast becoming a staple for many patients. Some of its medical uses include stress, anxiety, depression, migraine, pain, and arthritis. Since it's so versatile and multi-tasking, it's heaven-sent for people who are suffering from more than one medical condition.


Aside from the high THC content, this strain also boasts a cornucopia of terpenes, including limonene, beta-caryophyllene, alpha-pinene, terpineol, and ocimene. All of these contribute to the health-promoting properties of this ganja. To be specific, they provide potent antidepressant, anxiolytic, analgesic, anti-inflammatory activities. Some of them have also demonstrated antibiotic, antibacterial, anti-tumor, and antioxidant potential in scientific studies.


Terpenes also promote the so-called "entourage effect." This phenomenon describes how terpenes interact with THC and other cannabinoids to enhance their effects. 

Like its parents, Critical Jack also contains soaring THC levels, reaching as high as 20%. As always, consume in moderation and keep your tolerance in mind. Otherwise, you may experience anxiety and paranoia. So, if you're already predisposed to these two conditions, you'll have to be extra careful.


But even if you're careful, dry mouth and eyes may still ensue. These are completely normal reactions to high-THC varieties. To avoid this, remember to hydrate well before, during, and after intake. It helps to have a glass of water on hand, which allows you to relieve the bouts of dryness as soon as they appear. If your eyes are feeling extra dry or even itchy, use some lubricating or itch-relieving eye drops.

This Sativa-dominant hybrid is the ultimate daytime strain. At the onset, expect a subtle mental uplift, which immediately elevates your mood and leaves you feeling blissful. As the high soars to the heavens, the cerebral and euphoric kick also magnify. 

Once consumed, most Sativa varieties deliver a too-intense surge of energy - one that will make it impossible for you to work on analytical tasks. Critical Jack, in contrast, produces milder mental stimulation, allowing you to remain productive. In fact, with the focus-enhancing effects, you'll undoubtedly get things done in no time.


Alternatively, you could loosen up and enjoy yourself. This strain could induce fits of laughter, so it's a fantastic choice for a comedy marathon. Plus, it could make you more talkative and more sociable. So, if you're smoke circle is on the lookout for the next strain to toke up, look no further.


Expect the psychoactive ride to last for some time. At the come-down, you'll start feeling profoundly calm and relaxed - but without a hint of couch-lock. It ensures that you could go about your business without a hitch.

When it comes to the bouquet, Critical Jack is an undisputed champion. Upon opening the bag, it will tease your olfactory senses with an amalgam of scents. The sweet piney aroma stands out a mile, while the floral undertones and lemon zest only become apparent once the nugs are crushed or broken apart. You may detect a peppery kick, too. No doubt; just taking a whiff from the florets will already invigorate your senses and uplift your mood.
Thankfully, this Sativa-leaning is as flavorful and tasty as its aroma. It delights the palate with a spicy punch accentuated by hints of pepper. Even better, the smoke is light and velvety smooth, making it ideal for people who tend to cough or are easily irritated. Meanwhile, hints of wood, lemon, and fruits tend to linger behind once you exhale.

Critical strains are usually Indica-heavy hybrids that produce hefty yields and deeply relaxing effects. They're essentially a modern take on Big Bud - one of the nineties' most celebrated strains. If you want to try this strain family, consider Critical+ Fem. It's high-yielding and smells like freshly-picked lemons for an invigorating experience. Meanwhile, Auto Critical+ 2.0 Fem is the way to go if you want easy-to-grow plants with immense bag appeal.

On the other hand, Jack Herer is named after the American marijuana activist and author of the same name. The original strain is Sativa-dominant with euphoric and clear-headed effects. It's also incredibly well-rounded, making it an easy favorite among recreational and medicinal users alike.

Fans of fragrant varieties will love Jack Herer x Skunk Fem, which enjoys an irresistible bouquet of sweet citrus with a peppery, slightly musky twist. If you're a medical marijuana patient or simply ultra-sensitive to THC, consider CBD Jack Herer Fem. The balanced 1:1 CBD to THC ratio ensures that you could harness the plant's therapeutic benefits without an overwhelming high.

Any of these strains will be a splendid addition to your cannabis garden. And if you're a first-timer, they will make an excellent starting point.
