Critical Jack Strain Review – Bonza Blog

A cross between two world-renowned strains, Critical Jack has giant shoes to fill – that of Critical Plus and Jack Herer. The two award-winners have followers that, to this remain, loyal to its blissful mood-enhancing effects. Indeed, a tough battle for an offspring to fight.

The mission to prove it is as good as its predecessors was successful. With many acclaiming Critical Jack breaks the boundaries set by its family with its long list of selling points.

Serving an even split of Sativa and Indica effects, Critical Jack is a smooth strain that satisfies fans of both spectrums. Its cerebral elevation at the onset and full-bodied euphoria fills the missing ‘oomph’ of one’s morning. Together, it results in a blissful yet functional high that may as well be a contender for the ultimate daytime strain in the market. Moreover, its mental boost it provides is similar to coffee but without the crash.

Odor and Flavors

Critical Jack is packed with all things invigorating – notes of lemon peel add zest to tired and thirsty spirits. Meanwhile, the sweetness from crushed pine and flowers steadies the acidity of the flavors. Hints of propane add a pungent kick to the palate, but ultimately makes for a smooth and addicting smoke.


At first glance, Critical Jack may just seem like a quintessential pick-me-up bud. Upon closer inspection, however, the herb stands out not by a mind-warping or body-stoning high, but through its light yet profound effects that promote relief and alertness instead of a crippling euphoria.

The combination of its placid yet motivating buzz makes it ideal for morning use. It rouses the mind with just enough energy to ease users into a productive mood. Along with that comes an improved ability to concentrate on the daily routine with both enthusiasm and ease.

Another notable quality is how the muscle-relaxing sensation that usually creeps up after does not undo the wakeful onset, nor does it weigh the body down with the usual drowsiness that follows in some other strains. Instead, the body and mind merely co-exist peacefully, which is why Critical Jack is one of the best functional strains to date.

Adverse Reactions

Critical Jack may promise a mellow and uplifting high but using it beyond the limitations could cause adverse effects too. Apart from the typical dry mouth and eyes, some might suffer from bouts of dizziness. In extreme cases, those with low tolerance to the strong effects of THC may even feel levels of anxiousness or paranoia elevate. As such, it is better to start slow and steady to ensure a smooth-sailing experience.

Medical Use and Benefits

Critical Jack may be subtle, but the enrichment and relief it gives to patients is effective enough to be considered significant. This impact in the lives of many is what makes it exceptional to the medical community.

Its energizing onset gets rid of the previous night’s lethargy. Promoting an active lifestyle, its mood-elevating buzz assures that tasks are completed with gusto. At the same time, users can take advantage of the renewed zeal to quell a hearty appetite.

Other than dispelling chronic stress, the anxiolytic properties comfort the pre-occupied thoughts of the depressed mind. Filled with a sense of purpose, the need to pursue personal goals such as passion projects or simple errands is ignited once again.

Additionally, its high THC content is not limited to thrills and giggles only. It contains painkilling qualities that effectively remove common discomforts like backaches, arthritis and cramps. It takes pride in balancing a calm and clear-headed high for hours.

Growing Critical Jack

Ironically, its effects may be coveted for its gentleness, but the plant’s build is not one for subtleties. Reaching a towering height of up to 300 cm, it can be quite intimidating to grow Critical Jack. Although it may be challenging in some parts, the experience is quite positive for veterans and even beginners.

Some extra steps can easily fix its height problem – pruning and trimming helps encourage lateral growth and keeps it manageable in covert spaces indoors. It flourishes well in either hydroponics or organic soil, the latter being a better choice for enhancing its flavors. Moreover, employing the Screen of Green method helps reduce its vegetative period as well as encourage better bud growth.

When kept under the best care, indoor flowering should take between 8 to 9 weeks. Growers are rewarded with a hearty average of 600 grams per square meter.

Outdoors cultivation, on the other hand, is on a league of its own in terms of the massiveness of its turnout. The plant prefers the constant sun and heat of a Mediterranean but will do well in the cool weather of the northern hemisphere due to the influence of Critical Plus. Growers reap unbelievable yields of 1200 gram of fresh buds per plant by the end of September or early October.
