Alien OG Weed Review | Purple Alien Strain

alien og hybrid marijuana strain

With its high concentration of THC, Alien OG is among the strongest strains of marijuana and can quite literally turn you into an “alien.” First bred by seed company Cali Connection, this sativa dominant hybrid strain is a crossbreed of Tahoe OG and the already well known Alien Kush, sometimes called Alien Dream strain. Alien OG’s effects are primarily described as euphoric and relaxing with a nicely balanced body and cerebral high. It is also known by other names such as Green Alien strain, Tahoe Alien strain and Alien OG Kush.

Perfect for making edibles, this strain packs a strong, sweet piney aroma accompanied with bursts of citrus flavour. Newcomers are advised to stick to low doses with this heavyweight.

Is Alien OG a sativa or an indica?

Loved for its balanced body and cerebral effects, Alien OG strain is a 60:40 sativa leaning hybrid although some phenotypes can be more balanced at 50:50. The buds generally have a very compact and dense structure although some sativa leaning phenotypes can have looser leaves. They often have a beautiful frosty and moist appearance thanks to the trichomes that densely cover them.

What is OG weed?

There is some debate regarding the exact definition of OG, with some saying that it stands for “Ocean Grown” and others claiming “Original Gangster.” Most tend to lean towards the latter. A strain with OG in its name is related to the legendary OG Kush, either through several crossbreeds or directly.

OG Kush is known as being the parent strain of some of the best marijuana in the world, including the following:
  • Rebel OG
  • Kosher Kush
  • Crown OG
  • Phantom OG Kush
  • Grapefruit OG
  • Orange Sherbet


What does the OG family look like?

The descendants of OG Kush typically share many similar characteristics as its genes are at often times the dominant allele. Appearance-wise, their green buds are dense and heavily covered by trichomes, giving a mesmerizing silvery-white glow. OG Kush’s side effects are also passed down through its genes, possibly causing anxiety and dry eyes to the user at medium to high doses. People with low tolerance should use with caution.

Alien OG Kush genetics 

First brought to the market by Cali Connection in the California Bay area, Alien OG Strain genetics can be traced back to the Hindi Kush mountains of Afghanistan. Part of the ever-growing OG family, it is a crossbreed of Alien Kush and Tahoe OG, hence giving it its name. Both of these parent strains have already earned quite a reputation; Alien Kush is also a parent of many other notorious strains, after all it is nicknamed the Red Alien Queen. These strains include the Blue Alien strain, Purple Alien strain, Fire Alien Kush, Sour Alien OG, Alien Blues strain, and White Fire Alien OG.

Alien OG strain THC percentage 

As mentioned above, Alien OG Strain is one of the strongest strains by the THC level. While the average sativa strain has a THC concentration of 13%, the average Alien OG strain has been found to contain 20% THC. Some stronger phenotypes have recorded up to 28% THC. Therefore, this strain should be used accordingly as it can lead to paranoia in inexperienced users.
If you are looking for a strain that gives a similar euphoric and happy experience but not nearly as potent, we can recommend you Super Cheese strain, Nebula weed strain and Las Vegas Purple Alien Strain. They are all suitable for afternoon consumption and are less potent.

Alien OG strain price 

As it is a difficult strain to grow and store, Alien OG is relatively expensive. You should find it for around 15 dollars per gram (50 dollars an eighth) in a Californian dispensary. Consumers in the Netherlands can expect to pay up to 25 dollars a gram. Though pricey, just a little bit of this stuff is guaranteed to go a long way!

Alien OG strain, shatter, edibles, etc.

The high concentration of THC in Alien OG or Blue Alien Strain makes it a good choice for edibles, shatter, and other concentrates. Its super-dense buds are full of its distinct, sweet piney flavor.  Make sure the weed is well grinded before use to make the most out of the bud.  

If making edibles, you should use already vaped bud (AVB) especially because of Alien OG’s high potency. However, if you do prefer to use fresh buds for edibles, please be sure to decarboxylate your weed first!

With high enough doses, this strain can make you feel very sleepy and possibly very lethargic; should you feel unwell, you should either prepare a coffee or take a cold shower, this will make you feel better shortly.  


Alien OG strain flowering time

Alien OG typically flowers in 7 to 9 weeks. Although you can harvest it earlier, it is recommended you wait at least 7 weeks so that its potency can reach its reputation-making levels.

Alien OG strain Growing tips

This is a relatively difficult strain to grow because of the plant's highly sensitive root system. Therefore, it is best grown indoors in a well-controlled environment. Temperatures should be maintained at 20 - 26 degrees Celsius throughout the growing process.  A relatively short and bushy plant, larger leaves may need to be trimmed in order to allow for light and air to reach its lower parts.
Ensuring the best possible quality of Alien OG also requires a tricky curing process post-harvest; this aims to preserve the very high levels of THC. It consists of 2 stages: First, flowers must be hung upside down for 7 to 10 days in a dry environment. They should then easily snap off the stem and must be placed in airtight jars for storage, maintaining an optimal temperature of 20 degrees Celsius throughout curing and storage.

Alien OG strain yield 

Alien OG has an average to high yield; one can expect 3 - 6 ounces of fresh bud per square foot.

Alien OG seeds

Seeds are available from a number of dispensaries in the California Bay area, including the original breeders Cali Connection, where they go for 60 dollars for a pack of six seeds.
