Allen Wrench Strain

If one is unfamiliar of the unique aliases of cannabis varieties, the first thing that comes to mind when one hears the name Allen Wrench should be the actual hex key that is typically used for bolts and screws with hexagonal sockets.

However, among the cannabis community, the name represents one of the most sought-after strains in the market.

Allen Wrench happens to be famous for its potent and functional high.

Although this strain looks nothing like the actual tool, it works more or less the same way regarding productivity.

While the hex tool can satisfy one’s hardware needs at home to fix or assemble things, the Allen Wrench strain can spark enough motivational thoughts to get a user going and complete a day’s work.

Read on below to know more about what this strain is truly capable of.

Allen Wrench is an American strain that was developed by crossing the infamous mind-bending Trainwreck and the award-winning NYC Diesel.

Although, we do not know exactly who should take credit for the creation of this strain as its original breeder is still unknown.

Overall, Allen Wrench is a relatively new strain that embodies the best qualities of its two powerhouse parents which make it just as deserving of the recognition and respect from the entire cannabis community.

Most users would regard Allen Wrench’s type of high as the ultimate psychoactive experience, and they are not mistaken.

At the onset, users will feel a quick head rush with a noticeable pressure behind the eyes and temples.

However, this stimulating high is generally an uplifting and happy sensation that often induces creative thinking.

Allen Wrench Effects

Furthermore, users will notice a significant increase in their energy and find themselves in a state of euphoria that stimulates one’s social behaviors.

Thus, users become more chatty and giggly than usual.

Although the mental stimulation of Allen Wrench is usually too overwhelming, the overall experience becomes more comfortable as users begin to feel accustomed to its effects which can then be regarded as motivating rather than consuming.


Along with its unforgettable high, Allen Wrench also boasts of a strong, delightful aroma that is a combination of fruity, floral and earthy with a distinct hint of sourness to it.

The strain’s overall fragrance is reminiscent of a newly dug earth that is coupled with a skunky tang and complemented by the sweet tones of flowers and the zest of sour fruity.


Allen Wrench offers a crisp flavor of a sweet and citrusy fruit accompanied by the woody taste of pine.

When lit, the strain creates a smooth smoke that brings out its earthy and lemony traits even more especially upon exhale.

These flavors are basically what makes Allen Wrench a deliciously powerful strain that seasoned users greatly appreciate.

Adverse Reaction

Unfortunately, Allen Wrench’s powerful cerebral high is not meant for users who are susceptible to being panicky as the strain can easily cause anxiety.

Also, this is partly the reason why novice users should avoid this strain, including those with low tolerance to high levels of THC.

Allen Wrench Adverse Reaction

Moreover, the strain is also known to cause dry mouth, and on rare occasions, some users may experience dizziness which is often accompanied by signs of paranoia and dry eyes.


The dominant Sativa effects of the strain are proven to be beneficial in many ways.

For one, it is known to effectively suppress the symptoms of depression and clear the mind from any stressful thoughts.

At the same time, it can also improve the sense of focus in patients with ADHD.

Now, the Indica content of Allen Wrench is not totally useless. The strain still has enough analgesic properties to relieve pain and symptoms of fatigue.

Some users might also find the strain helpful in controlling nausea and in stimulating one’s appetite.

Unfortunately, the original seed stock of Allen Wrench is not available for commercial sale.

So, prospective growers may need to obtain clippings from a healthy plant and grow them as clones instead.

Allen Wrench Growing

However, the good news is that the strain can be cultivated either indoor or outdoor.

If grown indoors, the SCROG method is the best way to go to maximize the strain’s yields.

Also, note that the strain prefers a well-controlled nutrient level since it can be very sensitive to overfeeding.

For outdoor cultivation, it is advisable to grow the plant in a semi-humid or Mediterranean climate.

The strain can also give off a strong aroma while growing, so it is smarter to plant them away from nosy neighbors or better yet, keep them indoors and invest in odor-control devices such as a carbon filter or a simple exhaust fan.

Flowering Time


Indoors, the strain’s flowering period can be a long 10 to 11 weeks. Although, the yield is pretty rewarding at around 16 to 20 ounces per square meter.


If grown outdoors, the buds of Allen Wrench should be ready for harvest by late October, and the yields are just as generous at around 24 ounces or more per plant.
