Alien OG Effects and Potency

Alien OG is a potent strain with high THC levels. On average, it contains around 20% to 28% THC, making it one of the stronger strains available. CBD levels in Alien OG are relatively low, usually less than 1%. Its effects generally come on quickly after consumption. Upon inhalation or ingestion, users may start to feel the effects within minutes. The onset can be described as a sudden rush of euphoria and mental clarity, accompanied by a sense of relaxation spreading through the body.

Smoking or vaping this strain leads to faster effects; however, if you are looking to have a long-lasting effect that may linger on for several hours, consider eating edibles. The duration of Alien OG’s effects can vary depending on individual tolerance and consumption methods. Generally, the initial intensity of the high may last for about 1 to 2 hours, followed by a more mellow and sedative experience that can persist for several hours.

On the physical side, users often experience deep relaxation and a soothing, tranquil sensation throughout their body. Muscles may unwind, tension may dissipate, and a gentle sense of physical euphoria can wash over the user. This relaxing body high makes Alien OG an excellent choice for individuals seeking relief from chronic pain, muscle spasms, or physical tension.

Concurrently, Alien OG offers potent cerebral effects that uplift the mind and elevate the mood. Users often report a surge of euphoria, followed by an increase in creativity and mental clarity. The strain’s Sativa attributes contribute to a burst of energy and focus, making it suitable for daytime use for many consumers. This cerebral stimulation can be helpful for tasks that require creativity, problem-solving, or enhanced productivity.

Potential Positive Effects of Alien OG

  • Euphoria: Users often experience a surge of happiness and an uplifted mood, which makes it a great strain for those seeking stress relief or mood enhancement.
  • Relaxation: Alien OG induces deep physical relaxation, potentially helping with muscle tension and easing physical discomfort.
  • Creativity: The strain may stimulate creative thinking and imaginative thoughts, making it popular among artists and musicians.
  • Focus: Despite its relaxing properties, Alien OG can also promote focus and concentration, making it suitable for daytime use for some individuals.

Potential Side Effects of Alien OG

One of the most common side effects of using Alien OG is experiencing dry mouth. The strain’s potent THC content can reduce saliva production, leading to a feeling of dryness in the mouth and throat. Staying hydrated by drinking water or non-alcoholic beverages can help alleviate this discomfort. Alien OG can also cause dryness in the eyes, leading to redness, irritation, and itchiness.

Using over-the-counter eye drops can help relieve these symptoms. Due to its high THC levels, some users may experience dizziness or feelings of lightheadedness, especially when consuming large amounts or if they are new to using cannabis. Alien OG’s potency can trigger anxiety or paranoia, particularly in users who are sensitive to THC or prone to these effects.

It is crucial to consume this strain in a comfortable and familiar environment to minimize these potential drawbacks. The strain can cause a temporary increase in heart rate, which may be concerning for individuals with certain cardiovascular conditions. If you have any pre-existing heart conditions, it is advisable to consult a medical professional before using this strain.

Medical Applications 

Alien OG’s potential to induce hunger, also known as “munchies,” may aid individuals experiencing a loss of appetite or undergoing treatments that affect their appetite. The combination of relaxation and euphoria can be helpful for people with PTSD, helping them manage triggers and cope with emotional distress.

Alien OG’s antiemetic properties may provide relief from nausea and vomiting, particularly for those undergoing chemotherapy or dealing with gastrointestinal issues. Some users report that Alien OG helps alleviate intraocular pressure, making it potentially beneficial for individuals with glaucoma. Alien OG’s relaxing properties may help reduce chronic pain, such as arthritis, fibromyalgia, and back pain.

Its analgesic effects can provide comfort and ease discomfort. The strain’s euphoric and blissful high can be beneficial for individuals experiencing depression, as it may help elevate mood and create a more positive outlook. It may be helpful for those struggling with sleep disturbances or insomnia, promoting a sense of tranquility that can lead to better sleep.


Alien OG has an intricate flavor profile that entices connoisseurs of cannabis. When consuming this strain, either through smoking or edibles, users will get a taste of earthy flavors, evoking a sense of nature’s richness, along with a piney essence that brings to mind serene forests and tranquil wilderness. However, what truly sets Alien OG apart and makes it an intriguing choice for cannabis enthusiasts is the unexpected twist of a subtle, yet delightful, citrus undertone.

The same earthy and piney notes found in the aroma are mirrored in the flavor when the strain is consumed. Additionally, the presence of the citrusy undertone in the taste perfectly mirrors the hints of sweetness and zest that greet the nose upon smelling the buds. In comparison with a strain like Sour Diesel, the taste of Alien OG is generally smoother and less harsh. It has a distinct earthy and pine flavor, with subtle hints of fuel-like notes. Sour Diesel has a strong diesel-like taste that can be quite pungent. It also has prominent citrus and skunky undertones.


Alien OG has a pungent and earthy aroma that draws the attention of users easily. The powerful aroma is a fusion of fresh soil and pine needles that make the scent feel very natural and inviting. One of the most prominent notes in the Alien OG’s aroma is the strong pine scent. It’s reminiscent of a walk through a dense forest, surrounded by tall evergreen trees and the fresh aroma they release into the air. The pine scent gives Alien OG its freshness, making it particularly appealing to those who appreciate the great outdoors.

There is also an herbal undertone in the smell of this strain, which is reminiscent of crushed sage leaves or a subtle blend of various wild herbs. In comparison to other similar strains like Tahoe OG, both have a strong pine scent; however, Alien OG tends to have a more pronounced herbal undertone, while Tahoe OG leans slightly more towards lemon and citrus notes. Additionally, Alien OG’s pine and herbal scent differs significantly from the sweet and doughy aroma of GSC. While Alien OG has subtle fuel-like undertones, GSC features hints of mint and chocolate in its fragrance.


The buds of Alien OG have a vibrant and deep shade of green as their base color. However, what truly makes them stand out are the patches of dark purple and indigo hues that often swirl throughout the buds. These splashes of contrasting colors add to the strain’s visual appeal and give it a unique and alluring appearance. In some cases, you may also notice slight hints of rusty orange pistils intertwined among the dense foliage. The texture of Alien OG buds is typically dense and compact, with tightly packed calyxes that form a sturdy structure.

When you touch the buds, they feel firm and slightly sticky due to the presence of resinous trichomes. Running your fingers along the surface, you might experience a velvety sensation owing to the fine layer of trichomes covering the buds. Alien OG buds have a high density, which means they are tightly packed and solid. In comparison to another strain like Pineapple Express, Alien OG’s dense buds’ contrast with the slightly fluffier and less compact structure often found in it. Additionally, Alien OG’s deep purple hues are not present in the predominantly green buds of Pineapple Express.

Growing Information

Alien OG is a compact and bushy plant that often reaches a moderate height. Indoor-grown plants can reach around 2 to 4 feet (0.6 to 1.2 meters). This plant may grow slightly taller if it is cultivated outdoors. Indoor cultivation allows for better monitoring and adjustment of factors like temperature, humidity, and light, which can significantly impact the plant’s growth and overall yield.

Alien OG prefers a warm and temperate climate, with temperatures ranging between 68°F and 80°F (20°C and 27°C) during the day and slightly cooler temperatures at night. If growing outdoors, ensure that the strain is not exposed to extreme temperature fluctuations or frost. The strain has a relatively short flowering time, typically taking around 8 to 9 weeks to mature. Some phenotypes may finish slightly earlier or later, so it’s essential to monitor the trichomes’ color to determine the optimal harvest time.

During the vegetative stage, Alien OG prefers a slightly higher humidity level, around 60% to 70%. However, as it enters the flowering stage, it’s best to lower the humidity to about 40% to 50% to reduce the risk of mold and mildew formation. Maintaining a temperature range of 70°F to 80°F (21°C to 27°C) during the day and slightly cooler temperatures at night will generally promote healthy growth and resin production.

One potential challenge when growing Alien OG is its sensitivity to high humidity levels during the flowering stage. Excess humidity can lead to bud rot and mold issues, so it’s crucial to monitor and control humidity levels carefully. Due to its dense buds, good air circulation is essential to prevent any moisture buildup and potential problems associated with it. Another consideration is providing proper support to the branches, as the buds can become heavy during flowering.

Tips for Successful Growth

  • Pruning and Training: Prune and train the plant to encourage a bushier shape and improve light penetration to the lower parts of the plant.
  • Nutrient Balance: Use a balanced nutrient regimen during different growth stages to support healthy growth and maximize resin production.
  • pH Levels: Monitor and maintain the pH levels of the soil or hydroponic solution within the appropriate range (around 6.0 to 6.5) for optimal nutrient absorption.
  • Harvest Timing: Observe the trichomes using a magnifying glass to determine the best time to harvest. Wait until they are mostly cloudy with some amber for a balanced and potent effect.
  • Drying and Curing: After harvest, ensure a proper drying and curing process to preserve the strain’s flavor and potency.
  • Pest and Disease Management: Regularly inspect the plants for pests or diseases and take appropriate measures to prevent or treat any issues.

Cannabinoid and Terpene profiles

Alien OG has a relatively high THC content, often ranging between 20% and 28%. THC is the primary psychoactive compound in cannabis and is responsible for the strain’s potent effects. It generally contains low to moderate levels of CBD, a non-intoxicating cannabinoid known for its potential therapeutic benefits. The terpenes in this strain include Myrcene, Pinene, limonene, and Caryophyllene.

Myrcene is one of the most abundant terpenes in Alien OG. It has an herbal, earthy, and slightly musky aroma. It generally contributes to the strain’s relaxing and sedative effects. As the name suggests, pinene has a distinct pine aroma and is found in significant amounts in Alien OG. This terpene promotes mental alertness and focus. Caryophyllene acts as both a terpene and a cannabinoid receptor agonist. It binds to CB2 receptors in the endocannabinoid system, making it one of the few terpenes that can directly interact with the body’s cannabinoid receptors.
