Big-Yield, Award-Winning Classic Sativa
Jack Herer Feminized Seeds combine Jack Herer and Skunk in a tall, sativa-dominant photoperiod cultivar. Seedkeepers reports balanced effects, very dense resin production, 22% to 24% THC with 1% CBD, and very high yield potential. It can be grown indoors or outdoors and reaches around 63 inches in both settings.
This is a photoperiod variety. Indoor growers can control how long vegetative growth is and induce flowering by changing the light schedule. For a vigorous plant, the flexibility is ideal as the canopy can be manipulated prior to bloom. Feminized seeds eliminate the space that would have been used to identify and remove male plants.
Jack Herer x Skunk
Jack Herer is a legendary name in cannabis. It evokes images of thick resin with bright effects and a sharp pine-and-spice aroma. Skunk combines with it to enhance vigor, flower density, and an earthy sweet stink.
Balanced is the description Seedkeepers offers for the effects of this sativa-dominant strain. That balance may be a fog-free mental state that is alert, engaged and calm as the body. It is not about one overwhelming direction, but rather clarity with enough weightiness to keep everything composed.
Pine, Lemon, Pepper, and Fresh Herbs
The aroma is otherwise not dessert-driven. Pine and citrus often accompanied by black pepper, wood, sage, basil, and earthy Skunk. Some plants may show sweeter notes of orange or even floral.
Controlled curing can enhance the herbal elements while calming the sharper notes of pine and spice. Seedkeepers does not do terpene analysis for this particular cross, so the exact scent will differ based on phenotype and environmental factors. Medium used for cultivation, temperature, timing of the harvest, drying, and curing will affect the flower.
Resin's visual appeal and careful handling post-harvest is certainly justified. With Skunk in the lineage, taking precautions for odors in an indoor grow space is a good idea.
Effects are Balanced
At THC levels of 22% to 24% and with CBD at 1%, this is strong weed. Seedkeepers describes the experience as balanced, but even that is a subjective measurement. Smaller amounts will likely lead to conversation, music, focused activities, or creative pursuits. Larger servings will more likely push toward a heavier feel.
Influencing factors include control, setting, phenotype, harvest timing, serving size, and method of consumption. Newer consumers and those with lower tolerances should start with small servings and wait for a significant time before consuming more. Balanced should not be understood as mild.
Cultivating Jack Herer Indoors
Seedkeepers' difficulty rating for Jack Herer is medium, meaning it is suitable for intermediate growers. The stated height of 63 inches means you will need to plan vertically in a tent. Consider the pot, flowering stretch, and a safe distance from the light.
To create more of an even canopy, you can use topping, low stress training, and/or scrogs to distribute the branches and prevent one central top from dominating. Jack Herer has selections that range from 49-63 days for flowering, which is faster than some of the other selections. When determining whether to harvest, you should judge based on the maturity of the plant and not just what the calendar says.
Give consistent nutrition, adequate airflow, and a root zone that drains well. Dense flowers and a productive canopy means humidity control will be important towards the end of bloom. Seedkeepers lists indoor production at 1.6 ounces per square foot. This figure can be approached based on light intensity, vegetative time, root space, training, phenotype, and plant health.
Outdoor Cultivation
Jack Herer can thrive outdoors due to the free drainage provided by the soil, the consistent climate that allows for the entire flowering cycle to finish, as well as direct sunlight. Seedkeepers describes the yield as very high, estimating 21.2 to 28.2 ounces per plant. With a height of 63 inches, this strain is manageable for a Haze dominant plant.
Make sure to give branches room to spread, as continued vegetative growth may lead to branches being pulled sideways due to the weight of the flowers. In wet climates, it is advised to inspect the plant regularly as dense buds can be prone to rot and disease. Many factors including, soil volume and nutrients, plant health, season length, and climate will affect your outdoor yield.
Who Should Choose Jack Herer?
This strain is best for intermediate growers looking for a well-known name, easy photoperiod control, and a significant yield. It does well with planned canopies and is high yielding.
Jack Herer is recommended for lovers of pine, lemon, pepper, woods, fresh herbs, and balanced effects at 22%-24% THC. The strain's personality matches the classic Sativa-leaning description while it's high yield adds extra value.
