Spliff Seeds Jack F1 is the perfect choice for those seeking a potent Sativa strain with high yields, unique flavours, and powerful therapeutic effects.

A Sativa Dominant Masterpiece

Spliff Seeds Jack F1 is an exceptional strain bred from a Dutch crossbreed of Northern Lights, Skunk #1, and Mexican Haze. This 75% Sativa plant boasts an extremely high THC level and is renowned for its immense resin production. Despite its Indica appearance, Jack F1 delivers a classic Sativa high with a short flowering period, making it an ideal choice for both novice and experienced growers.

Vigorous Growth and Impressive Yields

Jack F1 is a vigorous plant that thrives in soil or coco, making it suitable for various growing environments. Indoors, the plant reaches heights of 150-180 cm, yielding 450-550 g/m² within a short flowering period of 63 days. Outdoors, it can grow up to 2-3 meters tall, producing up to 400 g/plant by October. This strain is known for its massive budding, forming a giant main cola covered in snowy crystals of resin from top to bottom. To manage its height, it’s recommended to keep Jack F1 on a 24/7 light schedule during the vegetative period and avoid overfeeding.

Unique Flavour and Therapeutic Effects

Jack F1 offers a delightful blend of flavours with sweet, spicy, and cinnamon notes, reminiscent of a classic Haze. Its aroma is equally captivating, with hints of cinnamon that enhance the overall sensory experience. The effects are long-lasting and predominantly cerebral, providing a euphoric and uplifting high that transitions into a soothing body buzz. This strain is highly medicinal, offering relief from conditions such as anxiety, arthritis, muscle and joint pain, inflammation, insomnia, and loss of appetite.
