Critical 2.0 XL Auto Cannabis 

Critical 2.0 XL Auto is their most popular auto-flowering strain currently available. This knowledge should be sufficient for everybody to know that this cannabis jewel expertly combines everything required to keep a cannabis producer happy, including stability, speed, vigor, yield, flavor, and potency. What else could a person anticipate from the offspring of two genetic lines as extraordinary as Critical + Auto & Critical +? A true cannabis delicacy!

Critical 2.0 XL Auto marijuana plants that have undergone auto-flowering have a relatively slender stem, are primarily Indica in genetic makeup and have short to medium distances between internodal nodes. Her Indica/Sativa leaves are of medium size, and they cover the whole body of this exceptionally vigorous plant. This plant’s only weakness is its inability to resist moisture, which is more than made up for by the rapidity with which she flowers, reducing the likelihood that fungi will infect it.

Critical 2.0 XL Auto is a strain that produces large quantities of dense, intense, and resinous Indica buds. This strain is a worthy successor to the Critical lineage.

Growing Critical 2.0 XL Auto Seeds

Growers have the option of cultivating Critical 2.0 XL Auto either indoors or outdoors. When deciding on a growing method, one must take into account the potent odor of the strain.  If the plant is to be grown inside, it is recommended that a grow tent or grow room be fitted with carbon filters. These filters will prevent the strain’s potent odor from accumulating unnecessarily in the space.

When growing the strain outside, it is best to do it in places free from nosy neighbors or other people who could be disturbed by the strain’s distinctive odor. If this is the case, potential growers have an additional responsibility to ensure that the plant is grown in tropical or Mediterranean climates.

The flowering period for Critical 2.0 XL Auto will be between 45 and 50 days, and the indoor growth of this strain has the potential to produce an outstanding output of roughly 22 oz per square meter. It is possible to harvest the flowers of Critical 2.0 XL Auto at the beginning of October if the plant is grown in optimal conditions and the harvest of 45 oz per plant is projected to be achieved.

Critical 2.0 XL Auto Weed Taste & Smell

Both Critical 2.0 XL Auto parents may be detected in its aroma, making it a hybrid with a symbiotic aroma. The smells of citrus and zest are more noticeable at the beginning, followed by strong undertones of pine and wood with a sharper, more intense quality. As the strain is smoked, this earthy undertone is brought to the forefront more and more. Critical 2.0 XL Auto generally has a robust and recognizable scent, which more seasoned consumers praise.

Some people believe that getting used to Critical 2.0 XL Auto’s flavor takes time and practice. Despite this, it is enjoyable enough for seasoned users who choose strains with potent flavors. To be more exact, it has a lemony undertone that gradually transforms into a taste reminiscent of chemicals.

Critical 2.0 XL Auto Marijuana 

The cannabis strain, Critical 2.0 XL Auto, is regarded as one of the most well-balanced hybrids available because it’s Indica and Sativa components are both present in equal measure. In addition, Critical 2.0 XL Auto is a worthy descendant of the legendary Big Bud & Skunk strains, both of which have significantly impacted the strain’s overall character. 

Because its THC content can reach 23%, Critical 2.0 XL Auto is best suited for more seasoned consumers that are more likely to be able to handle the intense effects of this strain.  In the beginning, the Skunk heritage of Critical 2.0 XL Auto comes out as consumers feel a high euphoric rush that puts smokers in an elevated mood along with innovative thinking and a better ability to concentrate.

On the contrary, this strain produces a high that is more sedative than energizing, which is a characteristic that was probably passed down from its Big Bud mother. The body buzz brought on by Critical 2.0 XL Auto is subtle and relaxing, and it doesn’t have any couch-lock characteristics.  When considering the body and head high that Critical Plus produces, it is easy to see why the strain is best experienced in the late afternoon or evening, either by oneself or in the company of companions.
