Appearance and Smell

OG 18  plants are of medium height, growing 4 to 6 ft. tall. The buds are dense and pungent. THC levels average about 18 %, creating a smooth smoke. The buds are medium green, sprinkle with orange pistils, and sticky resin, and frosty trichomes. This smoke is also called Private Reserve, as it is a secret delight among users in the know, part of their secret stash. Some users report that the visual look of it is misleading, due to it being unimpressive until the strong hit of diesel lights up your nose and mouth. There are also hints of pine and citrus, creating a strong, Kushy, and serious smoke for recreational and medical users alike.

How to Grow OG 18  Cannabis Seeds or Cuttings

Growing weed from OG 18  cannabis seeds or cuttings is said to require a small amount of care. These are strong, resilient, Kush plants. It produces a more bountiful yield than OG Kush, which is why growers love it. You can set up a grow tent indoors to get started. Place reflective lining around the inside of the tent to concentrate your light to get the photosynthesis occurring to make all the wonderful cannabinoids and terpenes that you want in your flavor profile. You can use 5-gallon buckets with rich, organic soil and fertilizer like Flower Power or your own mix. These plants can be grown hydroponically and using a screen of green, trimming, or sea of green to increase yields. After 8 or 9 weeks using a typical method, induce flowering by altering your lighting schedule. Harvest your bundles and hang to dry. Store in darkened mason jars and enjoy. You can get around 16 ounces per square meter of space.

You can also grow these plants outdoors or in a greenhouse. Your plants will flower around the early days of October. Expect to take away as much as 18 ounces of bud per plant.

Medicinal Marijuana Review / Chronic Pain

OG 18  is 70 percent Indica and 30 percent Sativa. THC levels can be between 16 % and 20 %. This can make it a great way to treat chronic pain.

People who suffer from chronic pain often only want as much pain relief as will get them out of pain and to be able to be productive. They don’t want to be high every day, couch-locked, or feel heavy and lazy. Many have rejected prescription opioid medication due to the side effects of forgetfulness, laziness, addiction, tolerance, and euphoria. Some prefer pain medications without much of a psychedelic effect. Sometimes this is not possible after they have exhausted the use of NSAIDs and paracetamol, which can themselves produce side effects like liver damage and stomach bleeding.

As a compromise, they may look into medical marijuana. It does not have the same severe risks of dependency and overdose death associated with opioid medications like fentanyl and Demerol. Also, a strain like OG # 18 packs a lot of pain relief without the sky-high THC levels found in other weed varieties. OG # 18 can therefore be easier to dose correctly than opioid medications or even stronger varieties of weed. It can be taken as a smoked herbal flower, so you can gauge dose effects immediately, as edibles can be trickier to dose.  A few hits can dispel troublesome pain and make work at a desk job possible for some sufferers, though as with other medications, users shouldn’t operate heavy machinery. This medical bud can take the edge off of back pain, neck pain, carpal tunnel syndrome, and even IBS pain such that you can concentrate on what you need to do to keep your family well provided for and thriving.  Those who need even less THC can look to strains like Harlequin and Cannatonic. Strains with less than 2 % THC may provide stress and pain relief with no head high. OG 18 is not one of these, it will produce a buzz, but it’s right in the middle, a good place to start if you and your doctor need to experiment a bit to find the right level for you.

Social Media Reviews






OG 18 is a great weed to wind the day down. Most of us have aches, pains, and cares that bother us that we know we shouldn’t focus on so much but which still plague us. While we are strengthening our minds to learn to turn our attention to the positive more perfectly, we need to minimize the damage that our stressful thoughts are doing to our immune system and body. Marijuana is not an anti-inflammatory because it causes you to relax, rather, it causes you to relax because it is an anti-inflammatory. It happens so quickly that even the smell itself is already turning on genes that tell your body’s immune system to heal rather than continue to go haywire due to chronic stress.

You will notice your meals are easier to digest and stresses are easier to handle without physical symptoms manifesting such as stomach problems, backaches, neck aches, and other manifestations of stress. A moderate smoke can become a healthy part of your arsenal for dealing with stress. Good luck!
