OG 18 Strain Review

Although it packs a punch, OG 18 doesn’t last as long as you would expect it to. Nevertheless, the finish is pleasant and not as nasty as you may think. It is relaxing and clean without any negative side effects.

It leaves your body feeling relaxed which is perfect for someone who suffers from pains and aches.

What Is OG 18?

OG 18 originally comes from DNA genetics. It is a phenotype (has the same traits and characteristics) of OG Kush. This strain is a Sativa-dominant hybrid also referred to as “Private Reserve.”

It tends to provide an intense cerebral high very soon after use. Many find it melts lingering doubts and worries away quite quickly. Not long after usage, your body usually starts to take hold and OG 18’s sedative effects begin.

Some users report that they feel happy and clear-headed but with little inclination to move around. A high from OG 18 can last for several hours and, in this time, you will probably experience an increased appetite. 

How Was OG 18 Developed?

The origins of the OG Kush strain are argued in some circles. There are many colorful stories about the OG family but most agree that it originated and was developed in Florida during the 1990s. Matt “Bubba” Berger, a grower, created a strain that he named “Bubba.”

Around the same time, Matt Berger also found another strain that originated from Seattle known as “Kryptonite.” The story goes that one of Buba’s friends referred to the strain as “Kushberreis.” this name stuck and was then shorted to “Kush.”

Upon moving to Southern California, Bubba met another grower called Josh D and, along with their mutual friend, Chris, started growing cannabis. The three growers created this extraordinary new West Coast strain known as “OG Kush” and it has been in circulation ever since. 


When you first smoke OG 18, you will notice an immediate burst of diesel flavor. If you’re familiar with Kush strains, you will know this fuel and pine flavor. Instead of experiencing notes of citrus that accompany OG 18’s aroma, you will more likely experience sourness.

Odor And flavor

OG 18 certainly provides a pungent odor as it grows. The closer it gets to flowering time, the more pronounced this pungent odor will become. 

Aside from its strong diesel scent and flavor, users can also experience some kind of earthiness and, occasionally, hints of citrus. 

Physical Appearance 

The buds of OG 18 are often thick, dense, and resinous. Their stickiness is usually down to a smidgen of white trichomes. The physical appearance of this strain is pretty attractive thanks to plenty of orange pistils on the surface.

Grow Info

Good news! Og 18 is quite easy to cultivate. It grows relatively well in indoor and outdoor environments. It is also resistant to most diseases, different pests, and mold. 

If you decide to grow OG 18 outdoors, it’s best if you live in a warm region such as a Mediterranean climate. If you grow it in a greenhouse, this can be an excellent cultivation experience too.

If you intend to grow OG 18 strain seeds indoors, you should consider using a hydroponic system. This will help increase the rate of growth and size of your harvest. Growing indoors will see a flowering time of around 8 to 9 weeks with OG 18. With around 16 to 18 ounces per square meter planted, OG 18’s yield is moderate to high.

When outdoors, OG 18 is typically ready to harvest by early October or, sometimes, by the end of September. In this environment, OG 18’s yield can be up to 20 ounces per plant. 

There are ways to encourage a higher number of buds by using some topping techniques alongside careful pruning. By pruning (trimming) off the tip of the OG 18 plant and then cutting away larger leaves, your final yield could be significantly boosted.


OG 18 can help soothe pains and aches. This is mainly due to its combination of a reasonable THC level and fast-acting effects. It can soothe the mind and make you more relaxed which is why it’s often used to assist with mental health issues such as depression or anxiety.

Side effects

High amounts of THC can induce dryness in the eyes and mouth leaving you very thirsty. For novices, its fasting-acting effects can cause dizziness.

It also has strong sedative effects which can leave you feeling very lethargic and stuck to the couch. 

Although rare, there is also a risk of occasional anxious thoughts after smoking OG 18 but this is more common with those who suffer from anxiety.

Medical Appointments 

Due to its relaxing and sedative effects, OG 18 is often used to help people who suffer from sleep disorders. It can also be very helpful for those who suffer from mental health issues as it can calm the mind as well as the body. This calmness also helps people who suffer pains and aches as the body relaxes completely.

Similar Strains 

Being a strain and a phenotype of the OG Kush, many strains in this family are similar. Some of the most similar strains include:

  • Tahoe OG
  • Bubba Kush
  • SFV OG
  • Fire OG
  • Headband
  • True OG
  • GSC

While OG 18 is different from OG Kush, it is similar enough to have quite predictable results which are, on the whole, usually pleasant.

Strain Cannabinoids 

  • THC Content – It usually has a high THC  content of 16-18% although some maybe around 20%.
  • CBD content – OG 18 has minimal strains as most THC-rich strains do. It has less than 1% and often just a little more than 0.1%.
