Meet Jack Herer Fast Version: iconic Sativa character with a quicker flowering cycle. This lively, mostly Sativa hybrid pairs bright, energetic effects with a vivid lemon-pine aroma and resin-rich buds. A smart pick for growers who want classic Jack Herer appeal and a faster route to harvest.

Our breeders created this fast-flowering cross from Jack Herer and Fast genetics. The Jack Herer lineage rose to fame in the 1990s, earning a reputation for distinctive quality and a long list of competition wins. Here, that celebrated heritage comes in a 60% Sativa, 40% Indica profile with a streamlined flowering time.

Expect sharp lemon and fresh pine up front, backed by pungent skunk and a spicy Haze-incense edge. A hint of black pepper deepens the aroma, while the smooth smoke carries the same bright, complex character from first impression to finish.

With THC levels around 15–20%, Jack Herer Fast Version delivers a cheerful, clear-headed lift. Creative, energetic, and focused, its Sativa-led effects suit active daytime moments and projects that call for a little extra spark.

Terpinolene leads the aromatic charge with a fresh, herbal mix of citrus, fruit, and pine. Alpha-pinene adds crisp forest notes, while gamma-terpinene brings a zesty lemon accent. The result is a lively terpene profile and a natural fit for customers seeking an upbeat, daytime experience. The variety is also associated with interest in arthritis, insomnia, and pain relief.

These fast-flowering seeds preserve the Jack Herer character while cutting the flowering period to just 6–7 weeks. The plants are described as moderately easy to grow and suitable for beginners. Grassfarmer backs every order with a germination guarantee, so you can shop with confidence.

Give seedlings a quality, well-drained medium with perlite, peat, or coco coir to help manage moisture. Establish steady conditions from the start and provide appropriate nutrients as plants move from seedling to vegetative growth. Outdoors, choose a sunny planting site and time sowing to suit your local season.

Plants reach about 1.2 m and develop a strong central stem with branching side growth. They grow indoors or outdoors, with a temperate climate as their preferred setting. Indoors, a spacious vertical setup and ScrOG training can help create an even canopy. Keep airflow moving, manage humidity as flowering advances, and stay alert to pests.

Flowering takes 6–7 weeks, with indoor yields around 400 g/m² and outdoor yields of approximately 800–1,000 g per plant under favorable conditions. Expect dense, rock-hard buds with a heavy coat of resin and a crystalline trichome finish. That resin production also makes the harvest appealing for extracts and concentrates.
