J1 Marijuana Strain Review [The 2019 Update!]

Our full review of this fantastic strain


As is the case with every other product you buy, if you want quality then you have to pay a little more. J1’s top-end price may be off-putting for some, but if you have a little extra cash in your pocket then you may want to consider purchasing this luxury cannabis strain. Hopefully, this review will help you make up your mind about whether or not you want to part with your hard-earned cash.

What is the J1 Strain?

J1, a.k.a. Jack One, is a sativa-dominant hybrid strain which is the offspring of the sativa Jack Herer and the hybrid Skunk No. 1, hence the name, J1. This strain is famous for its potent but clear-headed high, making it a great choice for cannabis smokers who like to “wake and bake.” J1 will leave you feeling euphoric, happy and uplifted as well as energized and focused, ready to take on whatever challenges come your way. This is definitely not a strain that you want to puff on before going to bed!

J1 has a high THC content which ranges between 18-23%, making this strain perhaps better suited to a more experienced cannabis smoker rather than a novice. J1’s high THC content is offset by a CBD level of around 0.01%.

J1 Strain Aroma, Flavor and Appearance

J1’s fragrance is a combination of sweet, citrusy scents as well as pungent skunky and piney aromas inherited from its parent strains. J1 has a citrusy taste with spicy flavors on the inhale and sweet flavors on the exhale making it a treat for the taste buds.

A J1 plant when fully grown is medium to tall in height, which produces large, emerald green and heavily frosted buds, with bright orange pistils that grow prominently around the leaves.

J1 Strain Grow Info

A J1 plant is considered to be of moderate difficulty to grow. This strain is probably not one for the novice grower with little or no experience for a number of reasons. A J1 plant can be grown indoors or outdoors as long as you grow it in a complex healthy soil medium. Growing your J1 plant in a high-quality soil rich in nutrients such as nitrogen, potassium and phosphorous will also help to maximize its flavors.

You can purchase a bag of premixed super soil for about twenty to thirty bucks or alternatively you can try your hand at creating your own super-soil at home. The guru of organic super soils, Subcool of TGA Genetics, revealed his super soil recipe in High Times magazine a number of years ago, which is now pretty much considered to be the best way to cultivate cannabis plants organically.

The buds of a J1 plant are densely packed together so good air circulation in your grow room is very important. The type of ventilation system you use for growing indoors can range from a fairly simple setup, such as one which includes intake and exhaust fans as well as recirculating fans. An experienced indoor grower may opt for a more sophisticated setup which also includes air conditioners, dehumidifiers and carbon dioxide enrichment equipment.

Whatever type of indoor ventilation system you use, your goal should be to keep the temperature and humidity level in the optimal range while providing your J1 plant with the carbon dioxide it needs for photosynthesis. The optimal temperature range for a J1 plant is between 68-80 degrees Fahrenheit. In order to prevent any mold or mildew forming on this plant, it is recommended that you closely monitor the humidity level in your grow room. Unlike most strains, J1 prefers a lower humidity during the vegetative stage and by the flowering stage, ensure that the relative humidity is at 40%.

A J1 plant grown outdoors prefers a warm, dry climate so it is important to grow it in a dry place where it won’t be exposed to rain showers. The flowering period for a J1 plant is between 8-9 weeks, with September being the ideal month for harvesting. The good news is that after all of your hard work and diligent care and attention while growing this plant, you can look forward to a moderate to high yield from this potent strain.

Medical Benefits of the J1 Strain

J1 is renowned for its many medical benefits, making this strain a good choice for the medicinal cannabis smoker. J1’s uplifting effect makes this strain a great antidote for stress and mood disorders like depression. The reenergizing buzz J1 gives you makes this strain a great energy booster for people suffering from chronic fatigue.

As J1 is a sativa dominant strain, it is less effective than other, more indica-dominant strains out there at alleviating pain. J1’s ability to enhance appetite as well as its use as an antiemetic is also rated very low, so medicinal cannabis smokers looking to alleviate these symptoms won’t find much relief by smoking J1 weed.

Possible Side Effects of the J1 Strain

The number one negative side effect associated with J1 is that it can cause increased anxiety in people unaccustomed to more potent strains. It may also cause mild dry mouth and dry eyes. Some J1 smokers have reported feeling a little dizzy after smoking this strain. In rare cases, smokers have said that smoking J1 weed gave them a mild headache.

Final Thoughts on the J1 Strain

It is easy to see why the J1 strain is becoming increasingly popular among cannabis smokers. Its effectiveness at boosting not only your mood but also your energy levels while maintaining a clear-headed focus makes it an ideal strain for the recreational smoker who likes to “wake and bake.” These positive effects are clearly also beneficial for the medicinal cannabis smoker who is looking to alleviate the symptoms of depression, chronic fatigue and stress.

However, some may find the cost of this strain to be prohibitive, preferring to opt instead for more affordable strains which produce similar effects. The potency of this strain also means that it is perhaps not suitable for everyone, as some people have reported feeling heightened anxiety after smoking J1 weed.

For the would-be J1 grower, if you are new to growing your own cannabis plants at home then this is not the ideal strain to start off with – you’re probably better off leaving this one to more experienced cannabis cultivators out there.
