Critical Blue Fem Strain Review
Critical Blue Fem is the lovechild of Critical and Blueberry. This Indica-dominant hybrid is a genetic masterpiece that retains its parents' finest qualities, elevating them to even greater heights. Like Critical, it's profoundly relaxing without an incapacitating cerebral buzz. Meanwhile, similar to Blueberry, it's also taste-focused and intensely aromatic. To top it all off, you also get visually striking buds that testify to its staggering potency.

Critical Blue feminized seeds are straightforward to grow but may require extra attention at times. For this reason, they're better suited for more experienced cultivators. But if you're a beginner who's up for a challenge, then this strain won't disappoint. To know what you're up against, make sure to research beforehand.


The plants are faithful to its mostly Indica genetics and manifest plenty of quintessential Indica traits. They tend to be small and compact, standing at about 80 cm in height. The foliage can be quite bushy, so you'll have to prune regularly to encourage airflow and keep molds at bay. 


One thing to love about Critical Blue is that it has a remarkable bag appeal. For an Indica-leaning strain, the buds are delightfully large. They're also hefty, tightly packed, and bursting with crystalline trichomes. The cream of the crop, though, is the colors. The nugs are rendered primarily in vibrant green, but exposure to lower temperatures will coax out the gorgeous shades of blue, pink, and even purple.

During the flowering phase, your precious babies will begin developing buds and producing resin. During this critical stage, you'll want to take extra care of your plants. Do your best to satisfy their needs and ensure that they won't get stressed out. Otherwise, the harvest quality and quantity may significantly lower. In short, you'll have to avoid slip-ups at all costs.


Indoors, Critical Blue finishes blooming within 10 to 12 weeks. It has a slightly longer flowering time than most Indica hybrids. If grown outdoors, the plants are ready for collection by September or October. To be sure, watch out for some common markers of harvest time, such as darkened pistils and milky white trichomes.

The compact, easy-to-manage size makes Critical Blue well-suited for indoor grow operations, especially for individuals who are short on space. To maximize the possible yields, consider the Sea of Green method. This technique also accelerates the growing cycle as a bonus, allowing you to harvest the colas much earlier than usual. In terms of growing methods, hydroponic is ideal if you want rapid, vigorous growth, while organic soil is the way to go if you prefer to bring out the strain's unique aroma. Come harvest time, you can anticipate about 15.9 to 17.6 ounces (450 to 500 grams) of gooey ganja per square meter.
Outdoor growers will be happy to know that Critical Blue also thrives outside. As with many marijuana strains, a temperate or Mediterranean climate is ideal. With lots of sunshine and space to grow, the plants can reach 150 cm in height. This Indica hybrid can churn out as much as 26.5 ounces (750 grams) of sticky buds per plant under optimal conditions.

Just like its parents, Critical Blue also has immense therapeutic potential. Even better, it's multitasking and can combat both physical and mental ills. So, if you're suffering from more than one condition, it means that you can only use a single medication to manage some of your symptoms.


The medicinal benefits of this strain are thanks to its high THC content and terpene profile. As you may know, THC is a chemical compound responsible for the psychoactive effects of weed. But it's more than that. Research also shows that it may have powerful antidepressant, analgesic, antispasmodic, anti-inflammatory, and anti-emetic properties. On top of all these, it could also boost appetite and induce sleep.


Terpenes, on the other hand, are aromatic compounds. However, they also exert therapeutic action and may even work in synergy with THC and other cannabinoids. The result is more potent curative potential. As for Critical Blue, it contains high levels of limonene, myrcene, beta-caryophyllene, and alpha-pinene. Altogether, these terpenes could help with anxiety, depression, chronic pain, inflammation, and sleeping disturbances. 

One of the most important things to know about high-THC varieties is that they could cause adverse reactions if consumed excessively. The same goes for Critical Blue. At high doses, it could cause or exacerbate anxiety, paranoia, and dizziness. So, if you're a first-time user, make sure to take it slowly.


Even at low concentrations, though, you may experience dry eyes and cottonmouth. Don't worry; this is entirely normal. Drink a glass of water or use some eye drops to relieve the sensations of dryness.

With an average THC content of 19-23%, Critical Blue packs quite a powerful punch. The high starts as a mild cerebral uplift coupled with a burst of euphoria. It will lift your mood while giving you peace of mind. After some time, the physical effects kick in, blanketing the body in sheer calm and relaxation. You'll also feel some glorious warmth spreading through your limbs, melting away aches and tensions. At the come-down, your body will start feeling heavier, with sleepiness quickly following suit. Since this hybrid causes the energy levels to decrease gradually, people often consume it after work or early into the evening.
When it comes to scent profile, Critical Blue is a sure winner. It's hardly surprising. After all, it features the genetics of one of the most aromatic strains in existence - Blueberry. As soon as you open the bag, the refreshing blend of berries and citrus assails the nose. If you sniff some more, you may also notice a hint of earthiness in the background.
Taste-wise, this Indica strain is quite similar to its aroma. Once combusted, it captivates the palate with an explosion of lemon berry flavor. Often, it's accompanied by sweet fruity notes. On the exhale, the pungency becomes even more robust, leaving a spicy aftertaste behind.

Award-winning and highly coveted among marijuana enthusiasts, Critical+ Fem is perfect if you're a fan of lemon-smelling strains. Once consumed, this ganja ushers in deep relaxation while boosting your mood and creativity. Such effects make it ideal for night-time use. The 12 to 16% THC content is also low enough for beginner users.

Another fantastic option for citrus lovers is Auto Tangerine Fem. The buds give off a medley of sweet and tangy aromas, which will immediately fill the room. Once ignited, the tangerine smell becomes even more pronounced, imparting some tropical flavors on the exhale. The psychoactive effects are upbeat and head-centric at the onset but eventually fade into profound tranquility.

If you're more of a berry lover, you certainly won't go wrong with Blueberry Fem. We're sure that you won't be able to resist the bouquet of sweet berries with pine undertones. For such a legendary strain, it's surprisingly straightforward to cultivate is also high-yielding. After a successful growing period, get ready to take home a generous harvest composed of stunning, multicolored nugs.

CBD Critical Mass Fem is an excellent choice if you want to try your hand on high-CBD cultivars. It boasts a balanced 1:1 CBD to THC ratio, which is a godsend for those who are extra-sensitive to the adverse effects of THC. Best of all, it's incredibly versatile and can be used to address both physical and psychological discomforts. If you're looking to relax after an arduous workday, this strain has got you covered, too.
