Jack Diesel is a buzzy sativa that builds on the strength of its uber-popular parent strains. This bud was created by Spain-based breeders Positronic, who have also devised Caramel Ice. It is a cross between well-balanced hybrid Jack Herer and the notoriously pungent NYC Diesel. A dynamic flavor profile accompanies an energetic, upbeat high. Jack Diesel’s THC content has been measured at between 12% and 23%.

Despite its potency, Jack Diesel’s flowers tend to be visually unimpressive. These buds are only small to medium in size and adhere in tight, popcorn-like clusters. They hold a tapered, pointed shape and have a typical indica bud structure, with a dense central core. The tightly-packed leaves are a mossy medium green and are wound through with orange and copper-colored pistils. Cloudy white trichomes finish off these pebbly flowers, accounting for their high psychoactivity.

Jack Diesel’s flowers give off an herbal, citrus-like aroma that may be familiar to fans of parent strain Jack Herer. Closer inspection of the buds reveal heady fumes of diesel. Meanwhile, grinding up the small nuggets gives off a dank and earthy funk. When combusted in a pipe or a joint, Jack Diesel burns with a smooth and easily palatable smoke. This smoke tastes both floral and fruity on the exhale.

Jack Diesel’s effects take hold rather quickly, as is typical of many sativa-leaning strains. At first, smokers may notice an increase in blood pressure to the face, resulting in an increase in salivation as well as some blushing. Some odd sensations may follow, like an intensification of certain sounds or colors. Once acclimated to these conditions, smokers are shot into Jack Diesel’s orbit, immersed in their suddenly loud and newly significant thoughts. Ideas or concepts that may not otherwise command attention may suddenly become absorbing, while certain causes like a phrase or a single word may provoke a chain of free association. This kind of cerebral thinking can be an efficient way to wrap up any complex, work-related tasks that require concentration and analysis. It can also help to occupy the consumer’s mind if they’re focused on mundane chores like cleaning the house or organizing your inbox. For many people, this brainy energy can manifest as talkativeness, making Jack Diesel a great social lubricant to encourage conversation and good vibes. As the high wears on, this mental energy begins to taper off and may be replaced by a palpable feeling of calm. While they may not necessarily want to go to bed, consumers who experience the backend of this high may be more likely to opt for relaxation than productivity. If still sufficiently motivated, though, Jack Diesel’s simultaneous activation of mental and physical faculties makes it a nice way to enjoy a quick jog or other forms of light exercise. Because it is so heady and energetic, Jack Diesel should be reserved for daytime -- or even wake-and-bake -- use.

Jack Diesel’s mentally-focused effects can have several applications for medical cannabis patients. It can enable those with attention deficit disorders to sustain focus on a single task. It can also grant a temporary reprieve from the symptoms of stress and depression. Physiologically speaking, Jack Diesel can dull some mild aches and pains like headaches or indigestion. It may also provoke hunger, making it an effective appetite stimulant for those who have lost their appetites to disease or to treatments like chemotherapy. Because it is known to bring about patterns of paranoid, recursive thinking, Jack Diesel is not a good option for patients who are prone to panic or who have a low THC tolerance.

Positronic has made seeds of Jack Diesel available for sale online. Once obtained, it can be grown indoors or out, although outdoor cultivation calls for a semi-humid climate with daytime temperatures between 70 and 80 degrees Fahrenheit. Plants tend to grow medium-tall and may require pruning to fit in limited indoor spaces. Jack Diesel flowers within 9 to 10 weeks when grown indoors and is ready for harvest in mid to late October when grown outdoors. It offers patients growers a high yield of between 47 to 56 grams (or 1.7 to 2 ounces) per square foot of plant.

Jack Diesel is a must-try for cannabis consumers, as it combines two titans of the breeding world. It’s a great smoke to share with some friends on your next camping trip.
